Effects of Calcium and Jasmonic Acid on CBF Expression in Spinach
农业科学与技术(英文版)(2011)
摘要
[Objective] This experiment aimed to evaluate the effects of calcium and Jasmonic acid(JA) on the expression of CBF in spinach. [Methods] The seedlings of spinach were treated with low temperature (4 ℃), JA or A23187, then used for detecting the expression of CBF by northern blotting. [Results] The results showed that the CBF expression was regulated by low temperature and JA positively. [Conclusions] Low temperature may increase the JA content of the cell firstly, then JA induced the increase of cytosolic calcium concentration ([Ca2+]cyt), and the JA induced Ca2+ transmitted the low temperature signal through CaM or CaM related proteins, regulating the CBF expression.
