Effects of drought on gene expression in Maize reproductive and leaf meristem tissue revealed by RNA-seq

ABSTRACT: Purpose: To study the effects of drought at the transcriptomic level on two different actively dividing maize tissue: the ovaries, and the leaf meristem Methods: The Illumina reads were mapped to the maize B73 reference genome using Tophat followed by transcriptome reconstruction using Cufflinks. The FPKM valuse were extracted from cufflinks output and an R package called Limma was used to identify differentially expressed genes under drought under both tissues Results and Conclusions: Different processes which were differentially expressed under drought in both tissues were identified and analyzed in detail. A working hypothesis was formulated to account for the observed susceptibility of the reproductive tissue when compared to the robust response of the vegetative tissue. This analysis also servers as a basis for future study on drought-induced embryo abortion.
