盐逆境下转基因耐盐小麦与其受体呼吸途径的动态变化
Dynamics of respiration pathway in transgenic salt-tolerant wheat and its receptor under salt stress.
摘要
Abstract
Using transgenic salt-tolerant wheat 89122 and its receptor Longchun 13 as test material, the dynamic changes of respiration pathway of wheat seedlings at different salt concentration were studied. The appearance of salt respiration was later in 89122 than in Longchun 13. The changes of Valt and pValt of both varieties had different patterns during salt stress process. Valt was suppressed by high salt levels, but could be induced by low salt levels in Longchun 13. The pValt and p′Vcyt of two varieties were cooperatively regulated with each other to adapt to salt stress, and ρ′Vcyt was the main electron transport pathway The possible physiological roles of cyanide-resistant respiration were also discussed. It was suggested that the operation intensity of cyanide-resistant respiration could serve as a physiological index of plant salt-tolerance.关键词
