Transcriptome profiling of peanut gynophores revealed global reprogramming of gene expression during early pod development in darkness.

ABSTRACT:

Background

After the zygote divides few times, the development of peanut pre-globular embryo and fruit is arrested under white or red light. Embryo development could be resumed in dark condition after gynophore is buried in soil. It is interesting to study the mechanisms of gynophore development and pod formation in peanut.

Results

In this study, transcriptome analysis of peanut gynophore was performed using Illumina HiSeq™ 2000 to understand the mechanisms of geocarpy. More than 13 million short sequences were assembled into 72527 unigenes with average size of 394 bp. A large number of genes that were not identified previously in peanut EST projects were identified in this study, including most genes involved in plant circadian rhythm, intra-cellular transportation, plant s
