Abstract
Ovule produces female gametes, egg cell and central cell in flowering plant angiosperms. In the other side, anther produces male gamete, pollen. Two sperm cells in pollen migrate to fertilize egg cell and endosperm in the process termed double fertilization. Fertilized egg cell and central cell differentiates to embryo and endosperm to form seed , respectively.
These reproductive developmental processes, in which many kind of differentiated cell join, are sensitive to environmental stresses. However, we do not know why these processes are so sensitive to environmental stresses.
To identify hormonal signaling pathways involved in these phenomena, we searched for mutants show sensitivity to high temperature stress at plant reproductive development in A.thaliala.
Consequently we identified three lines that are sensitive to high temperature at flowering stage.In this meeting, we will discuss about how these mutants get weak/strong to stress and report further search for stress sensitive/tolerant mutants.
