Technical Abstract: To investigate regulatory processes and mechanisms underlying the development of peanut seeds, 8 x 15k microarrays were used to monitor changes in the transcriptome of a runner peanut genotype. Developing peanut pods from six development stages corresponding R2 through R8 stages were profiled. Several clusters of gene profiles were identified with different time-scales. We will discuss our findings on genes involved in a variety of cellular functions like lipids and starch synthesis, signal transduction, energy metabolism, seed maturation including desiccation tolerance, and proposed models demonstrating how novel pathways may impinge on the molecular mechanism of pod development in peanut.
