I would like to promote a discuss if the recent global climate changes can influences microsporogenesis, microgamatogenesis, megasporogenesis and megagametogenesis. I was wondering, based on the million years of terrestrial plant existence, if the plants can adapt the sporogenesis and gametogenesis for the possible changes in climate. Also, what is you thought about the possible plasticity in crop plants?
@ Joao, plant fertility is highly sensitive to elevated temperatures. Heat stress has pleitropic effects on male sporogenesis. Heat interferes with male meiotic cross-over designation and cell wall formation, providing a mechanistic basis for plant karyotype change and genome evolution under high temperature conditions. The male reproductive system has been repeatedly found to be most susceptible to temperature stress.
Dear Dr. Tarafdar,
Thank you for the reply. I understood what you say but I was wondering if during the hundred of million years of evolution if the plants did not evolve enough molecular machinery to tolerate the elevated temperatures or radiation. Thanks
Some plants at elevated temperature say 27oC experiences more branching in flower formation. So I think plants will evolve to survive on temperature depending on the growth stage.
