Genome-wide association study dissects the genetic bases of salt tolerance in maize seedlings.

Abstract: Excess salinity is a natural stress that causes crop yield losses worldwide. The genetic bases of maize salt tolerance remain largely unknown. Here we investigated the survival rates of 445 maize natural accessions after salt treatments. A skewed distribution of the salt-tolerant phenotypes was observed in this population. Genome-wide association studies (GWAS) revealed 57 loci significantly associated with salt tolerance. Forty-nine candidate genes were detected from these loci. About 10% of these genes were co-localized with loci from QTL mapping. Forty four percent of the candidate genes were involved in stress responses, ABA signaling, stomata division, DNA binding/transcription regulation and auxin signaling, suggesting that they are key genetic mechanisms of maize salt tolerance. Transgenic studies showed that two genes, the salt-tolerance-associated-gene 4 (SAG4, GRMZM2G077295) and SAG6 (GRMZM2G106056), which encode a protein transport protein and the double-strand break repair protein MRE11, respectively, had positive roles in plant salt tolerance, and their salt-tolerant haplotypes were revealed. The genes we identified in this study provide a list of candidate targets for further study of maize salt tolerance, and of genetic markers and materials that may be used for breeding salt-tolerance in maize.

Identification of juvenile hormone-active alkylphenols in the lobster Homarus americanus and in marine sediments.

Abstract: We have identified, by gas chromatography/ mass spectrometry, four alkylphenols that are present in the hemolymph and tissues of the American lobster Homarus americanus and in marine sediments. These alkylphenols are used industrially in antioxidant formulations for plastic and rubber polymer manufacturing, and are similar in struc-

Differentiation of self, need fulfillment, and psychological well-being in married men

Abstract: The contributions of differentiation of self and need fulfillment within the marital relationship to the experience of psychological well-being were examined in a sample of 95 married men. Differentiation of self, interactional-emotional need fulfillment, and sexual need fulfillment were each associated with higher scores on psychological well-being. Perceived interactional-emotional need fulfillment was identified as the most important predictor of well-being, followed by differentiation of self, and then perceived sexual need fulfillment. Regression analysis indicated that collectively these variables accounted for a significant proportion (27%) of the variance in well-being within the sample. Men who perceived their marital partners to be meeting their interactional, emotional, and sexual needs and who are able to maintain interdependent relationships with their partners were more likely to experience positive mental health. The results point to the importance of attending to issues of self-differentia...

Non-parametric methods in psychological research

Abstract: In recent years statistical techniques have been developed which do not rely on parameters of a known distribution in making statistical inferences. These have been called non-parametric or distribution-free methods. The main presentations of this subject matter with which psychologists are familiar are probably those by Edwards ( 8 ) , Moses ( 22 ) , Mosteller and Bush ( 2 3 ) , and Siege1 (27). However, there are numerous other treatises in this area (e.g., 14, 21, 31). These techniques have been developed mainly to avoid the need for making numerous assumptions as is the case with parametric techniques, thus providing certain advantages. However, in light of recent research it appears that at least with one parametric technique some of the assumed advantages of non-parametric analyses cited have been premature inasmuch as the assumptions of this parametric technique are not as restrictive as once supposed. The purpose of this paper is to consider effects of failure to meet assumptions of the analysis of variance technique on subsequent tests of significance and to suggest that in this area non-parametric techniques be given very limited use in psychological research.
