Abstract: the synthesis of onion (allium cepa) hybrids relies upon the use of two genetic-cytoplasmic male-sterility systems, cms-s and cms-t, in association to the normal male-fertile (n) cytoplasm. however, the molecular phenotyping of male-sterility-inducing and normal cytoplasms of many onion accessions adapted for cultivation under tropical conditions is not available. some of these accessions were reported as presenting tolerance to diseases and adaptation to tropical and subtropical regions. therefore, these accessions are potential sources of parental lines for the brazilian onion hybrid breeding programs. in the present work, polymerase chain reaction (pcr) assays were conducted using mitochondria-derived markers in order to characterize the cytoplasm type present in different morpho-agronomic onion types cultivated in brazil. the s cytoplasm appeared to be the most frequent one among the 66 evaluated accessions with a frequency of 56%. the t male-sterility-inducing cytoplasm was observed in 25.8% of the accessions. of the samples, 18.2% displayed exclusively the cytoplasm n. this information could be useful to guide the onion breeding programs in the selection of parental lines aiming to develop hybrid cultivars adapted to tropical and subtropical areas of the world.

Abstract: onion is a crop of significant socioeconomic importance to brazil. onion germplasm with adaptation to tropical and sub-tropical conditions has played an important role in the development of this crop in the country. in this context, we studied the genetic diversity in a germplasm collection potentially useful for the development of cultivars for tropical and subtropical regions. the genetic variability of 21 accessions/cultivars that have been used as germplasm and/or were developed by onion breeding programs in brazil was evaluated via rapd markers. the following accessions were included in the study :'red creole', 'roxa ipa-3', 'valenciana 14', 'beta cristal', 'diamante', 'composto ipa-6', 'aurora', 'bojuda rio grande', 'alfa tropical', 'pêra ipa-4', 'primavera', 'belém ipa-9', 'crioula alto vale', 'conquista', 'pira-ouro', 'vale-ouro ipa-11', 'franciscana ipa-10', 'serrana', 'cnph 6400', 'petroline', and 'baia periforme'. from the 520 primers used in the initial screening only 38 displayed stable polymorphisms. they produced 624 amplicons, of which 522 (83.7%) were monomorphic and 102 (16.3%) were polymorphic. an average similarity coefficient of 0.72 was calculated among accessions based upon this subgroup of polymorphic amplicons. this allowed the discrimination of this germplasm collection into six groups with only one of them comprising more than one accession. the main group was formed by 16 accessions ('diamante', 'composto ipa-6', 'aurora', 'bojuda rio grande', 'conquista', 'pira-ouro', 'serrana', 'vale-ouro ipa-11', 'baia periforme', 'primavera', 'franciscana ipa-10', 'belém ipa-9', 'crioula alto vale', 'petroline', 'pêra ipa-4' and 'alfa tropical'), for which the genetic origin (with few exceptions) can be traced back to the variety 'baia periforme'. the populations 'red creole', 'roxa ipa-3', 'beta cristal', 'cnph 6400', and 'valenciana 14' comprised a set of five isolated groups, showing genetic divergence among them and in relation to main 'baia perif

Abstract: the differentiation and development of somatic embryos were observed in 15 genotypes of sweet potato using shoot tip explants with one or two leaf primordia. somatic embryogenesis was induced using ms media and vitamins, 3% sucrose, 0,2% phytagel, supplemented with 2,4-d (0,0; 0,5; 1,0 and 2,0 mg/l). the cultures were maintained in the dark at 27oc. the addition of 2,4-d was necessary for embryogenic callus induction in the genotypes '92', '94', '184', '188', '319', '370', '374', '442', '449', '549', '594', '645', 'pi3138463', 'white star' and 'jewel'. clones '169', '202', '605', '633' and '643' did not respond to embryogenic callus induction. embryogenic callus showed a yellow and opaque color, compact and granular texture. nonembryogenic callus was translucent in color and friable. calluses were originated at the periphery of explants. in the established conditions better formation of embryogenic calluses was obtained with 2,0 mg/l of 2,4-d. the transfer of embryogenic callus to 2,4-d free medium allowed embryo development to heart, torpedo and cotiledonary stages.

Abstract: Introduction: Cerebrovascular accident (CVA) is the second most frequent cause of death in the world. Nevertheless, most victims do survive and need treatment, and hand function is one that has to be dealt with in the rehabilitation process. Kinesio®?Taping (KT) is a bandaging method that can be applied along the muscle fibers to provide stimulation. Studies have shown its efficacy in providing afferent stimuli to weakened muscles, thus eliciting contraction with greater recruiting of motor units and inducing neuroplasticity. Benefits to the paresthesia hand have not been reported. Objective: Investigate the effects of KT on hand function in hemiparetic patients. Material and Methods: An evaluator-blinded, randomized clinical trial involving stroke victims was carried out in a physical therapy outpatient clinic. One group underwent KT intervention and the other was a control group. The Modified Ashworth Scale (MAS) and the Box and Block Test (BBT) were used as assessment tools. A data entry form was used in the Epi-info 7 software and descriptive statistics was thus calculated. The software BioStat 5.0 was employed when doing statistical tests. Associations were regarded as statistically significant when p < 0.05. Results: Eight individuals were randomly assigned to two groups. All those who had received treatment with KT had spasticity improved by one point, but there was no significant improvement in BBT. Conclusion: KT was effective when it came to improving spasticity and it may be an option in rehab, but it had no effect on gross manual dexterity. Nevertheless, it can be of help as part of a functional training program.
