"Arabidobrassica": Chromosomal recombination and morphogenesis in asymmetric intergeneric hybrid cells.

abstract：:Changes in gene expression related to ethylene synthesis were investigated during ripening of tomato fruit, and in unripe fruit and leaves after wounding. Messenger RNA was extracted at different stages of ripening, or at various times after wounding, and translated in vitro. A number of changes in mRNA were noted in ...
