Maintaining Genome Integrity during Seed Development in Phaseolus vulgaris L.: Evidence from a Transcriptomic Profiling Study.

ABSTRACT: The maintenance of genome integrity is crucial in seeds, due to the constant challenge of several endogenous and exogenous factors. The knowledge concerning DNA damage response and chromatin remodeling during seed development is still scarce, especially in Phaseolus vulgaris L. A transcriptomic profiling of the expression of genes related to DNA damage response/chromatin remodeling mechanisms was performed in P. vulgaris seeds at four distinct developmental stages, spanning from late embryogenesis to seed desiccation. Of the 14,001 expressed genes identified using massive analysis of cDNA ends, 301 belong to the DNA MapMan category. In late embryogenesis, a high expression of genes related to DNA damage sensing and repair suggests there is a tight control of DNA integrity. At
