MicroRNA profiling of peanut embryos under calcium-deficiency and -sufficient conditions. Arachis hypogaea

Peanut embryo development is a complex process involving a series of genes regulatory pathways and is easily affected by a variety of elements in the soil. Calcium deficiency in soil induces early embryo abortion in peanut, which provides an opportunity to unravel the mechanism underlying this important event. MicroRNA (miRNA)-guided target gene regulation is vital for a wide variety of biological processes. To better understand the molecular basis for peanut early embryo abortion under calcium deficiency, we performed small RNA analyses in peanut early embryo
