Interactions between nitric oxide and aquaporin in seed germination of wheat
摘要
Abstract
In order to explore the interactions between nitric oxide (NO) and aquaporin (AQP) in seed germina-tion ,two wheat varieties including Shaanhe No .6 (SH6 ,drought-resistant) and Zhengying No .1 (ZY1 ,drought-suscep-tible) were adopted to study the effects of H2O ,HgCl2 (500μM) ,PEG (PEG-8000 ,-0 .35 MPa) ,SNP (0 .5 mM) , SNP+PEG and SNP+HgCl2 solution soaking on seed germination .The results showed that SNP (NO donor) promoted seed germination of the drought-resistant variety ,while inhibited that of the drought-susceptible variety .AQP played a more important role in the drought-susceptible variety than in the drought-tolerance variety .NO could relieve the inhibi-tion of seed germination caused by drought or aquaporin inhibitor (HgCl2 ) .The inhibition degree of stress to germination of the seeds being imbibed was smaller than that of the seeds being germinated directly .NO could regulate the activity of AQP ,and both NO and AQP exerted their role mainly in the initial 12 h of germination .关键词
