Changes in gravitational forces induce modifications of gene expression in A. thaliana seedlings.

abstract：:A study has been made of the changes occurring in Zea mays kernels exposed to thermal shock at the 48th h of soaking at 16°C, i.e., just before the protrusion of the root. Heat shock of 5 h at 46°C temporarily inhibits the resumption of root growth and consequently retards the protrusion of the root. On the ultrastruc...
