Transcriptome Analysis of a New Peanut Seed Coat Mutant for the Physiological Regulatory Mechanism Involved in Seed Coat Cracking and Pigmentation.

Seed-coat cracking and undesirable color of seed coat highly affects external appearance and commercial value of peanuts ( L.). With an objective to find genetic solution to the above problems, a peanut mutant with cracking and brown colored seed coat (testa) was identified from an EMS treated mutant population and designated as "peanut seed coat crack and brown color mutant line ().

Identification of ERF genes in peanuts and functional analysis of AhERF008 and AhERF019 in abiotic stress response.

Ethylene-responsive factor (ERF) play an important role in regulating gene expression in plant development and response to stresses. In peanuts (Arachis hypogaea L.), which produce flowers aerially and pods underground, only a few ERF genes have been identified so far.
