摘要

Inhibition of crop productivity by salt stress is mainly due to its impact on crop growth. Cell wall is an important component of plant biomass. Salt stress inhibits growth through affecting cell wall loosening. Expansins are cell wall proteins that promote wall loosening. Thus, cell wall-related genes and expansins play roles in regulating salt stress tolerance. The present review summarizes the major research advances in elucidating the importance of cell wall-related genes and expansins in salt stress tolerance.

鹽分逆境影響作物生長進而降低產量。細胞壁是生質量 (biomass) 之主要成分。鹽分逆境經由影響細胞壁鬆軟而抑制生長。擴展蛋白 (expansins) 是鬆軟細胞壁之蛋白。因此，細胞壁相關基因與擴展蛋白對作物調控鹽分逆境耐性扮演重要功用。本文說明細胞壁相關基因與擴展蛋白在水稻耐鹽重要性之主要研究進展。
