摘要: As the dominant species of the green tide-forming algae in the Yellow Sea of China during the past four years, Ulva prolifera was proposed as having evolved a perfect response mechanism to deal with different light and temperature stress. The LHCSR (also known as LI818 in green algae and LHCX in diatoms) protein is a stress-related member of the LHC family found only in algae. The homologues in the green alga Chlamydomonas were up-regulated in response to a variety of stresses and required for energy quenching. In this study, we cloned a putative lhcSR full-length cDNA sequence from U. prolifera and analysed the expression in response to various temperature and illumination gradients. The results showed that expression of lhcSR was up-regulated by light and transiently accumulated in 1 h. Expression of lhcSR could also be induced by low-temperature stress and could sustain the up-regulation for up to 6 days. These data suggest that the lhcSR gene in U. prolifera is involved in the adaption to the light and low-temperature stress in both the short and long term.
