چکیده انگلیسی
Information is limited on sulfur (S)-sources inside plant cells for synthesis of the proteins for acclimation to S-starvation. We found that a green alga, Chlamydomonas reinhardtii, when transferred to S-starved conditions, degrades 85% of a chloroplast membrane lipid, sulfoquinovosyl diacylglycerol (SQDG), to redistribute its S to a large part of protein fraction as early as by 6 h. Furthermore, the degradation of SQDG preceded that of proteins such as ribulose bisphosphate carboxylase/oxygenase, the candidates of internal S-sources. SQDG was thus demonstrated to yield a major internal S-source for protein synthesis during the early phase of acclimation process to S-starvation.
