Identification of candidate tolerance genes to low-temperature during maize germination by GWAS and RNA-seqapproaches.

ABSTRACT:

Background

Maize (Zea mays L.) is one of the main agricultural crops with the largest yield and acreage in the world. However, maize germplasm is very sensitive to low temperatures, mainly during germination, and low temperatures significantly affect plant growth and crop yield. Therefore, the identification of genes capable of increasing tolerance to low temperature has become necessary.

Results

In this study, fourteen phenotypic traits related to seed germination were used to assess the genetic diversity of maize through genome-wide association study (GWAS). A total of 30 single-nucleotide polymorphisms (SNPs) linked to low-temperature tolerance were detected (-log10(P) > 4), fourteen candidate genes were found to be directly related to the SNPs, further additional 68 gene
