Contrastant banana accessions for resistance to the burrowing nematode, based on molecular markers RAPD.

This work aimed to proceed molecular characterization of seven banana accessions (Borneo, Grand Naine, 1304-06, 4249-05, 0337-02, 0323-03 and 4279-06) resistance to the nematode Radopholus similis. These accessions were selected taking in account the reproduction factor (RF) among 26 banana genotypes from a working collection belonging to Embrapa Mandioca e Fruticultura Tropical. The genomic DNA of the seven accessions was extracted, and 36 decamere primers had been used to obtain RAPD markers. The resulting markers were converted into a matrix of binary data. From that matrix the genetic distance between the accessions were estimated, for further clustering and graphic dispersion analyses. From a total of 521 RAPD markers generated, 420 (81%) were polymorphic, including 140 (27%) potentially promising for application on works related to genetic mapping of the resistance to R. similis. OPE-15, OPH-17, and OPG-09 were the primers that contributed to the highest number of bands promising for genetic mapping of resistance (12, 8, and 8, respectively). The genetic distances between accessions ranged from 0.106 to 0.455, with the longest one observed between cv. Borneo and the genotype 4279-06, considered as highly susceptible and resistant, respectively, to the nematode according to the RF. The graphic dispersion distinguished three groups of accessions, and most of resistant genotypes clustered together in the same group. The most contrastant genotypes for resistance (Borneo and 4249-05) were separated by a genetic distance of 0.374, and possessed a total of 114 polymorphic bands promising for genetic mapping of resistance. In addition, the results of pathogenicity tests were congruent with those obtained by RAPD analyses

Changing Attitudes About Being a Bystander to Violence: Translating an In-Person Sexual Violence Prevention Program to a New Campus

Bystander approaches to reducing sexual violence train community members in prosocial roles to interrupt situations with risk of sexual violence and be supportive community allies after an assault. This study employs a true experimental design to evaluate the effectiveness of Bringing in the Bystander™ through 1-year post-implementation with first-year students from two universities (one rural, primarily residential; one urban, heavily commuter). We found significant change in bystander attitudes for male and female student program participants compared with the control group on both campuses, although the pattern of change depended on the combination of gender and campus

Resistance sources to root-knot nematodes Meloidogyne javanica, M. incognita and M. enterolobii in sweet potato

This study aimed to assess the resistance levels of 44 sweet potato genotypes to M.javanica, M. incognita race 1 and M. enterolobii. These researches were carried out in 2014, under greenhouse conditions in Brasília-DF, Brazil
