Some popular rice varieties grown in high elevation of India
and Nepal are HPU1, Kanchan, Himali, Himdhan, Himalaya1,
K332, Kalimpong1, Khonorullo and Meghalaya1.
An early maturity indica rice variety Zhefu 49, whose grain
quality and starch structure are sensitive to environmental
temperature, was subjected to different temperature (32ºC
for high temperature and 22ºC for optimum temperature) at
grain fi lling stage in plant growth chambers, and the different
expressions of their isoform genes (SBE1, SBEIII, SBEIV)
encoding starch branching enzyme in the endosperms were
studied by the real time fl uorescence quantitative PCR (FQ-PCR)
method. Effects of high temperature on the SBE-expression in
developing rice endosperms were isoform-dependent. High
temperature signifi cantly down regulated the expressions of
SBEI and SBEIII, while up regulated the expression of SBEIV.
Compared with SBEIV and SBEIII, the expressions of SBEI in
Zhefu 49 rice endosperms was more sensitive to temperature
