Analysis of the genes controlling three quantitative traits in three diverse plant species reveals the molecular basis of quantitative traits

摘要

Up- and down-enrichment of the genes controlling a quantitative trait that are subjected to RNA alternative splicing. Of the genes controlling ginseng ginsenoside biosynthesis (GSB), cotton fiber length (UHML), maize grain yield (GY), those spliced into two or more transcripts were up-enriched, while those spliced into single transcripts were down-enriched, relative to those of all genes expressed in the tissue. The asterisks “**” indicate the significance of  ≤ 0.01 determined by Chi-square test for which the percentages of the genes out of all genes expressed in the tissue with two or more transcripts and the genes with single transcripts were used to calculate the expected ones (see ref. ).
