Abstract
The germinated first seeds were treated with a solution containing SNP,NAC and LNNA under different light signals (such as darkness,photoperiod and enhanced UV-B) to explore the relationship be- tween the growth and NO production in coleoptiles.The results show that NOS-like activities were measured in the cellular microsome and cytosol of the coleoptiles.The exogenous NO might inhibit NOS activities through a negative feedback,but increased the growth of the coleoptiles,whereas the endogenous NO signif- icantly depending on the NOS-like activity inhibited the coleoptile growth.It was well-known that darkness contributes to coleoptile growth ang development.Compared with the darkness signal,the enhanced UV-B inhibited the NOS-like activity to decrease endogenous NO production and promoted the coleoptile growth, while the photoperiod signal sharply contrasted with the enhanced UV-B signal in its function.At the same time,SNP,NAC and LNNA inhibited the NOS-like activity and endogenous NO production and increased the coleoptile growth by various mechanisms.Therefore,the effects of different light signals on the growth of maize coleoptiles were achieved through the production regulation of endogenous NO signal moleculars in the coleoptile.
