Update publication information. we developed a research strategy whereby two conventional sorghum cultivars with contrasting salt sensitivity, the highly tolerant landrace cultivar Gaoliangzhe (GZ) and hypersensitive improved cultivar Henong16 (HN), were initially cropped with a normal nutrient solution for 14 days and then some seedlings were placed under saline conditions for varying time periods. We performed proteome analysis to reveal the striking changes protein pools. By comparing the proteome profiles of root tissues grown under salt stress, we have obtained valuable information for understanding the salt tolerance mechanisms of sorghum and provided a better utilization for saline land
