A new screening technique for tolerance to high concentrations of boron, namely a filter paper technique, and a soil experiment were compared to investigate the response of wheat genotypes known to differ in tolerance to high concentrations of boron .Under high boron concentrations in filter papers, the more tolerant genotypes had significantly longer roots than those of the more sensitive genotypes . There was no significant correlation between the root lengths at the control treatment and the other three boron treatments (50, 100, 150 mg B L -1 ) . Thus, the differences in root lengths at the high boron treatments could not be attributed to inherent differences in root growth but to the genetic variation in response to high boron concentrations among varieties .Root lengths at the three boron treatments in filter papers were highly significantly correlated with the three characters determined for plants grown in soil containing high levels of boron, namely the concentrations of boron in the shoots, plant dry weight and plant symptoms, indicating that root length could be used as a selection criterion in a genetic study or breeding program for boron tolerance .
Alfalfa seeds were treated with chlorine to determine the effect on microbial populations during soaking, sprouting, and refrigerated storage in three packaging environments. Chlorine was effective in reducing microbial populations on the seeds, but numbers increased during sprouting. Chlorine treatments had the most impact on yeast and molds during storage. Yeast and molds were significantly higher in sprouts that were stored in vacuum packages and in sprouts from non-chlorine treated seeds stored in MAP. Yeast and mold counts on all sprouts stored in perforated packaging did not significantly increase during storage. A combination of chlorine treatment of the seeds and preforated packaging of sprouts may increase the shelf-life.
In the version of this article initially published, some of the text on p 882 was inaccurate. The correct text should read as follows: "thereby counteracting the beneficial effects of blocking IAPP on islet inflammation" (middle column) and "This mechanism has been suggested to mediate ROSdependent inflammasome activation induced by high concentrations of glucose in mouse pancreatic beta cells 12 , although this finding is now being debated" (right column, first full paragraph, second sentence). The errors have been corrected in the HTML and PDF versions of the article. In the version of this article initially published, the actin loading control in Figure 6b (left) was incorrect. The correct figure is provided here. The error has been corrected in the HTML and PDF versions of the article. e r r ata a n d c o r r i g e n d a
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
