Often used as a proxy for the transition to reproduction, flowering time (FT) is an integrative trait of two successive biological processes, bolting time (BT) and the interval between bolting and flowering time (INT). In this study, we aimed to identify candidate genes associated with these composite traits in using a field experiment. Genome-wide association (GWA) mapping was performed on BT, INT and FT based on a sample of 179 worldwide natural accessions genotyped for 216,509 SNPs. Read More

Space experiments permit to understand better some phases of the gravitropic reaction which occurs when the orientation of the root changes in the gravitational field. In gravisensing cells (statocytes in the root cap), the nucleus is attached to the cell periphery, close to the plasma membrane, by actin filaments. The location of the amyloplasts (statoliths) depends also greatly on these elements of the cytoskeleton. Read More
