| pubmed-article:21437581 | pubmed:abstractText | Plant invertases catalyze the conversion of sucrose to glucose and fructose, which are distinct signals of widely varied stress-tolerance processes, including the biosynthesis and detection of hormones under water deficit. In the invertase gene family, the candidate gene ivr2 encoding plant acid-soluble invertase plays a vital role in drought tolerance. In this study, a putative genomic sequence of ivr2 including three exons and two introns was acquired and genetically analyzed using bioinformatics and statistics, based on a partial ivr2 gene sequence of the GenBank library. The ivr2 genomic sequence data from 106 maize inbred lines were obtained using five nested primer pairs. Further analysis showed that the detected polymorphic sites were mainly located in exon-1, intron-1 and exon-2 regions; High linkage disequilibrium level and low nucleotide diversity were identified at this ivr2 locus. Association mapping combined the genotypic and phenotypic data, and a total of 48 associations showed high contributions to the variations in grain yield and its components under well-watered and water-stressed conditions over 2 years of experiments. This suggested that functional polymorphisms in ivr2 were possibly associated with maize drought tolerance. This provides reference information for efficient marker-assisted selection of superior alleles in drought tolerance breeding programs. | lld:pubmed |
