Abstract

Abstract: In this study,two alfalfa (Medicago sativa L.) materials 'Baoding’ and 'ZN-1’ were treated with the mixed saline-alkali solution (NaCl∶Na₂SO₄∶NaHCO₃∶Na₂CO₃ in 1∶1∶1∶1 ratio at pH 9.3) at the concentrations of 0 mmol·L^-1,40 mmol·L^-1 and 80 mmol·L^-1,and compared for the tolerance. The morphology,physiology,and expression of the selected genes that are involved in ROS-scavenging,ion transport,and photosynthetic regulation were investigated at the alfalfa seedling stage,to look into the response to mixed saline-alkali stress. The results showed that with the increase of mixed saline-alkali concentration,significant (P＜0.05) damage was observed in the plant height,dry weight,chlorophyll content,photosynthetic rate,and Fv/Fm,in both the alfalfa materials. Compared with 'Baoding’,'ZN-1’ demonstrated significantly higher saline-alkali tolerance,as evidenced by higher plant height,more biomass,more contents of chlorophyll content,proline,and soluble sugar,stronger antioxidant activity,promoted robust photosynthesis,and less accumulation of ROS in leaves and Na⁺in root. In 'ZN-1’,the significantly up-regulated genes were associated with the pathways of ROS scavenging,proline biosynthesis,Na⁺ vacuolar compartmentalization,and chlorophyll maintenance. In summary,proline biosynthesis,Na⁺ vacuolar compartmentalization,chlorophyll maintenance,and antioxidants may play an important role in the 'ZN-1’ tolerance of mixed saline-alkali stress.

Key words: Alfalfa, Mixed saline-alkali stress, Physiological responses, Genes expression

摘要： 本研究以'ZN-1’和'保定’苜蓿(Medicago sativa L.'Baoding’)为试验材料，以浓度梯度为0 mmol·L^-1，40 mmol·L^-1和80 mmol·L^-1，pH值为9.3的混合盐碱溶液(NaCl∶Na₂SO₄∶NaHCO₃∶Na₂CO₃摩尔比为1∶1∶1∶1)进行胁迫处理，比较2个紫花苜蓿幼苗的生长指标、生理指标和基因表达(ROS清除、离子转运和光合调控3类基因)差异,以期为解析紫花苜蓿耐混合盐碱胁迫响应机制提供理论依据。结果表明，随着混合盐碱胁迫浓度的增加，2个紫花苜蓿的株高、干重、叶绿素含量、光合速率以及Fv/Fm等均出现明显的损伤(P＜0.05)。其中，'ZN-1’的耐混合盐碱性显著高于'保定’苜蓿，主要表现为'ZN-1’的株高和生物量更高、叶绿素含量和抗氧化酶的活性更高，净光合速率更强，脯氨酸和可溶性糖含量更高，叶片ROS积累量和地下部Na⁺积累更少，ROS清除、脯氨酸生物合成、Na⁺液泡区隔化以及叶绿素维持相关编码基因的表达水平更高。因此，脯氨酸生物合成、Na⁺液泡区隔化、叶绿素维持以及抗氧化酶可能在'ZN-1’耐混合盐碱胁迫中发挥重要作用。
