Transcriptome Analysis of Calcium- and Hormone-Related Gene Expressions during Different Stages of Peanut Pod Development.

ABSTRACT: Peanut is one of the calciphilous plants. Calcium serves as a ubiquitous central hub in a large number of signaling pathways. In the field, free calcium ion (Ca²⁺)-deficient soil can result in unfilled pods. Four pod stages were analyzed to determine the relationship between Ca²⁺ excretion and pod development. Peanut shells showed Ca²⁺ excretion at all four stages; however, both the embryo of Stage 4 (S4) and the red skin of Stage 3 (S3) showed Ca²⁺ absorbance. These results showed that embryo and red skin of peanut need Ca²⁺ during development. In order to survey the relationship among calcium, hormone and seed development from gene perspective, we further analyzed the seed transcriptome at Stage 2 (S2), S3, and S4. About 70 million h
