Natural populations of wild potato species are the backups for the diversity held in genebanks for research and breeding. Some potato species are known to grow in close proximity to cultivated fields, thus are potentially impacted by human activity, including exposure to pesticides. The present study tested the effects of a common pesticide on reproductive traits of potatoes known to grow in or near pesticide-treated fields in central Peru. Furadan? 4F, an insecticide— nematicide (common name = carbofuran) was applied at two different rates to populations representing 15 wild potato species in a greenhouse environment in Peru. Flowering duration of these populations was usually significantly reduced in comparison to a water control, and in a few cases, percent viable pollen also was. These findings suggest that agrichemicals may be having unintentional effects on wild potato populations in ways that could compromise their genetic diversity.

Objective:To investigate the possible association between rs7754840 and rs7756992 polymorphisms of CDKAL1 gene and susceptibility to gestational diabetes mellitus(GDM)in a Filipino pregnant ***:A total of 101 patients with GDM and 99 women without GDM were *** CDKAL1 gene single nucleotide polymorphisms(SNPs),namely rs7754840 and rs7756992,were genotyped by using TaqMan allelic discrimination ***-Whitney U test,median and interquartile range were used to describe physical and biochemical *** differences in the genotype and allele distribution of the target genetic variants among the two groups of participants were assessed by using Chi-square *** to Hardy-Weinberg equilibrium was tested prior to conducting further *** logistic regression model was used to investigate the effects of the genotype models on GDM ***:There was no observed correlation between the genotypes of the rs7754840 SNP and oral glucose tolerance test ***,there was no significant association between genetic models of the rs7754840 SNP and GDM risk(additive OR 1.43,95%CI 0.82-2.50,P=0.21;dominant OR 1.21,95%CI 0.57-2.59,P=0.62;recessive OR 1.63,95%CI 0.86-3.09,P=0.13).Conclusions:The results of this study suggest no association between CDKAL1 gene variant rs7754840 and GDM development in Filipino pregnant *** studies with a larger population should be performed to validate our findings.
