Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Pós-graduação em Agronomia (Genética e Melhoramento de Plantas) - FCAV; A couve comum (Brassica oleracea L. var. acephala DC) pertence à família Brassicaceae e de provável origem a região mediterrânea, atualmente têm ampla distribuição nos cinco continentes, desenvolvendo-se bem em temperaturas amenas, entretanto resiste bem ao frio e a geadas leves. No Brasil, a produção está localizada predominantemente em pequenas áreas do centro-sul do Brasil. O consumo das brássicas está associado ao seu alto valor nutricional, como fonte de vitaminas, minerais e fibras, bem como na prevenção de certos tipos de câncer, além de suas folhas apresentarem altos teores de fibras, imprescindíveis para boa digestão. Dentre os fatores que podem comprometer a produção encontram-se o inseto-praga Plutella xylostella (L., 1758) (Lepidoptera: Plutellidae), conhecida no Brasil como traça-dascrucíferas que ataca cultivares de couve, repolho, brócolis, cenoura e aipo. Seus danos são graves ao limbo foliar, chegando a comprometer economicamente a cultura, ocorrendo em todas as regiões produtoras de brássicas do país apresentando maiores populações em períodos quentes e secos.

Pós-graduação em Patologia - FMB; Compounds obtained from fruits, vegetables and essential oils have been widely used to treat many diseases. The allyl isothiocyanate (AITC), also known as mustard essential oil, is found in plants of the cruciferous family and is abundant in the mustard seeds. Due to its high bioavailability in urine, AITC has been considered as a promising antineoplastic agent against bladder cancer. Therefore, the aims of this study were to investigate the toxicogenetic and toxicogenomic effects of AITC in the wild-type (RT4) and in a mutant (T24) TP53 bladder transitional carcinoma cell lines. AITC was tested at concentrations of 0.005, 0.0625, 0.0725, 0.0825, 0.0925, 0.125 and 0.25 μM in the cytotoxicity and cell and clonogenic survival assays; in the comet and micronucleus assays, flow cytometry, apoptosis and gene expression (ANLN, BAX, BCL-2, CDK-1, SMAD4, S100P e TP53) evaluations the concentrations of 0.005; 0.0625; 0.0725; 0.0825 e 0.0925 μM were used. The results showed increased primary DNA damage in T24 (0.005, 0.0625, 0.0725, 0.0825 and 0.0925 μM) and RT4 (0.0725, 0.0825 and 0.0925 μM) cells. However, no significant difference was detected in the frequency of micronucleated cells. A significant increase of cells at sub-G1 phase (0.0625...

Descrevemos, no presente trabalho, as características morfológicas dos grãos de polem de 78 espécies apícolas mais conhecidas, os quais, na sua maioria, não haviam sido ainda descritos. Após esses estudos, elaboramos uma chave para a identificação e comparação, pelo polem, das espécies estudadas. As 78 espécies estudadas pertencem a 68 gêneros e distribuem-se por 28 famílias, sendo 3 subordinadas à classe Monocotyledoneae e as 25 restantes à classe Dicotyledoneae. O material polínico para a preparação das lâminas foi, na sua maioria, colhido diretamente das anteras das flores recém-abertas, no laboratório, somente seis espécies provieram de material de herbário. Todo o material polínico foi tratado pelo método de acetólise, e montado em geléia de glicerina colorida com Fucsina básica. As observações microscópicas e as mensurações dos grãos de polem foram feitas com o auxílio de um microscópico Zeiss, tomando-se as medidas em 5 grãos de polem, em vista equatorial, e 5 em vista polar. Empregamos a chave-principal para as classes de polem segundo FAEGRI e IVERSEN (1950) para separar em grupos os grãos de polem estudados de acordo com as suas características morfológicas, dando em resultado 10 grupos distintos. As espécies pertencentes a cada um dos 10 grupos...

The effects of root diffusates of selected plants within the families Chenopodiaceae and Cruciferae and the hatching agent zinc chloride were tested for their effects on hatching and emergence of juveniles from cysts of Heterodera schachtii and a race of H. trifolii parasitic on Chenopodaceae and Cruciferae in The Netherlands. Although all diffusates strongly stimulated hatching of juveniles of H. schachtii, their effects on H. trifolii were less evident.

Heterodera schachtii and H. cruciferae are sympatric in California and frequently occur in the same field upon the same host. We have investigated the use of polymerase chain reaction (PCR) amplification of nematode DNA sequences to differentiate H. schachtii and H. cruciferae and to assess genetic variability within each species. Single, random oligodeoxyribonucleotide primers were used to generate PCR-amplified fragments, termed RAPD (random amplified polymorphic DNA) markers, from genomic DNA of each species. Each of 19 different random primers yielded from 2 to 12 fragments whose size ranged from 200 to 1,500 bp. Reproducible differences in fragment patterns allowed differentiation of the two species with each primer. Similarities and differences among six different geographic populations of H. schachtii were detected. The potential application of RAPD analysis to relationships among nematode populations was assessed through cluster analysis of these six different populations, with 78 scorable markers from 10 different random primers. DNA from single cysts was successfully amplified, and genetic variability was revealed within geographic populations. The use of RAPD markers to assess genetic variability is a simple, reproducible technique that does not require radioisotopes. This powerful new technique can be used as a diagnostic tool and should have broad application in nematology.

Ten cultivated plants of the family Cruciferae were evaluated for susceptibility to Meloidogyne arenaria race 1, M. incognita races 1 and 3, and M. javanica in a series of four separate greenhouse tests. After 62-64 days, or 1,032-1,072 degree days (10 C base), several of the crops evaluated showed moderate to severe levels of galling (> 3.0 on 0-5 scale) and moderate numbers of egg masses (>2.0 on 0-5 scale) in response to each of the nematode species and races. Among the plants tested, collard (Brassica oleracea var. acephala) cv. Georgia Southern was the least susceptible (fewest galls and egg masses) to each of the four nematode isolates. Similar low levels of infection were obtained with broccoli (B. oleracea var. botrytis) cv. De Cicco in response to M. incognita race 1 and M. arenaria. Numbers of second-stage juveniles hatched from eggs per root system were variable in the test with M. arenaria, but lowest on collard for each of the other nematodes. Some commonly grown crucifers are hosts to several different species and races of Meloidogyne, which should be considered if these crops are included in cropping systems.

Phylogenetic analysis of new ribosomal DNA (rDNA) data for Heterodera mediterranea, H. hordecalis, H. carotae, and H. fici from Italy and H. ciceri from Syria, along with published data for other species, showed high bootstrap support for the following relationships: (((((H. carotae H. cruciferae) H. goettingiana) (((H. trifolii H. ciceri) H. mediterranea) ((H. avenae H. latipons) H. fici))) (Cactodera betulae H. hordecalis)) (Globodera rostochiensis G. pallida)). The rDNA sequence data were for the two internal transcribed spacers (ITS1 and ITS2) plus the 5.8S gene between them. These inferred relationships support the classic 'Goettingiana Group' of H. carotae, H. cruciferae, and H. goettingiana. A clade comprised of Cactodera betulae and H. hordecalis is only distantly related to the other species in the analysis.

• Background and Aims Vella pseudocytisus subsp. paui (Cruciferae) is a narrow endemic plant to the Teruel province (eastern Spain), which is listed in the National Catalogue of Endangered Species. Two distinct ploidy levels (diploid, 2n = 34, and tetraploid, 2n = 68) have been reported for this taxon that belongs to the core subtribe Vellinae, a western Mediterranean group of shrubby taxa with a chromosome base number of x = 17. Allozyme and AFLP analyses were conducted (a) to test for the ploidy and putative palaeo-allopolyploid origin of this taxon, (b) to explore levels of genetic diversity and spatial structure of its populations, and (c) to address in-situ and ex-situ strategies for its conservation.

Field studies on the influence of surrounding collards with non host plants revealed that the flea beetle, Phyllotreta cruciferae (Geoze), occurred significantly (P < 0.05) more on nonbordered control collards (x = 121.2) than on collards bordered by catnip (x = 77.0), southern wood (x = 58.7), tansy (x = 49.5), and wormwood (x = 40.5). However, P. Cruciferae counts on collards bordered by hyssop (x = 100.4) and santolina (x = 83.1) were not significantly (P > 0.05) different from the control. Foliage damage in all treatments, including the nonhost companion plantings, was extensive and reduced the marketability of the vegetable. Thus, although companion planting significantly reduced P. Cruciferae populations in some situations, it did not protect the plants from economic damage.

Numerical trends of flea beetle, Phyllotreta cruciferae (Geoze), populations on collards intercropped with nonhost polyculture vegetables were studied in Chesterfield County, Va., during 1981, 1982, and 1983. No significant differences in the number of beetles between intercropped and monocropped collards existed when collards were intercropped in rows 91 cm apart. Differences in the width of row spacing did not significantly influence beetle colonization on collards for plants intercropped with row spacings of 46, 61, and 76 cm. However, beetle populations were significantly smaller, and collard foliage was damaged significantly less in intercropped collards than in monocropped collards. Also, collard leaf yield was significantly less in intercropped regimes than in monoculture regimes. These data show that although intercropping reducedP. cruciferae populations on collards, the reduced collard leaf yield minimizes the usefulness of intercropping as a cultural method for controlling flea beetles on collards.

Fraction I proteins contained in 14 species representing five genera of Cruciferae were analyzed by isoelectric focusing. Two types of large subunit polypeptides whose isoelectric points are coded by extranuclear DNA and four different small subunit polypeptides coded by nuclear DNA were identified. One small subunit polypeptide was found only in Sinapsis arvensis; the remaining three were distributed among the 13 other species. No correlation was discernible between fraction I protein composition and relatedness between the 14 species as determined by the cytogenetic analysis of Mizushima6 Fraction I protein composition of three alloploid Brassica species whose diploid progenitors had been determined showed that multiple small subunit polypeptides arise by allopolyploidy wherein the amount of each polypeptide in the alloploid is approximately one-half that contained in the parent. The results also showed B. nigra to have been the female partner with B. oleraceae in the genesis of B. carinata and the male partner with B. campestris in the genesis of B. juncea. Absence of a difference in large subunit polypeptides between B. oleraceae and B. campeslris disallowed determination of which species was the female in the genesis of B. napus.

Abstract: Free radicals are formed throughout cellular metabolism. As fairly unstable and highly reactive substances, they are able to cause oxidation and sometimesirreversible damage to the cells, compromising their function. Although produced at high levels, most of them can be inactivated by antioxidants. The Cruciferae family has many species that are important for the regular human diet, as they provide important antioxidant components such as vitamins, minerals, fibers, flavonoids, carotenoids amongst others phytochemicals. As such, it is important to evaluate their antioxidant potential as they are routinely present as part of the Brazilian folk meals. In the present work, the antioxidant capability of the extracts prepared from white cabbage (Brassica oleracea var. capitata L.j, kale (Brassica oleracea L. var. acephala D.C.J, cauliflower (Brassica oleracea L. var. botrytis L. subv. cauliflora), broccoli (Brassica oleracea L. var. botrytis L. subv. cymosa), water-cress (Nasturtium officinalis L.) and radish (Raphanus sativus radiculal L.J, obtained from conventional, hydroponics, and organic agricultural procedures whereas possible, was investigated in vitro by the chemical methods of phosphomolybdenum complex and DPPH.

This work evaluates the use of cabbage leaves, Brassica oleracea var acephala (Cruciferae family) to stabilize bone mass in 13 menopausal women. The mature leaves were used after removal of the midrib and petiole and taken as a juice and given to the patient once a day for 24 months. Densitometric exams were performed every six months. The measurement points were the Trocanter and Ward's triangle. According to the results found, the use of cabbage leaf juice results in bone mass stabilization at the points studied, with perspectives for its use as an important option in disease prevention.

This paper deals with the studies of pollen grain characters from 78 honey plants, belonging to 68 genera of 28 families, three of them belonging to the class of Monocotyledons and 25 to the class of Dicotyledons. Pollen grains of 72 species were collected directly from fresh material (flowers opening in laboratory). Pollen of the six species were collected from herbarium material. All pollen grains were treated by acetolysis method and mounted in glycerine jelly stainde with basic Fuchsine. Zeiss microscope was used in examen and for mensuration. Ten grains were measured (five in equatorial view and five in polar view and five in polar view). This number was considerated satisfactory according to preliminar statistical: analysis of variance. For each species was determinde the average and standard error and coefficient of variability of mensuration of equatorial and polar diameter. FAEGRI & IVERSEN'S master key of-pollen grains was used.
