Differential Gene Expression in Sugarcane Leaves Regulated by Ethephon during Early Growth Stage
A study was conducted to investigate differential gene expression in sugarcane (Saccharum officinarum L. cv. ROC16) leaves subjected to 200 mg L-1 ethephon. cDNA-AFLP amplification showed a high level of polymorphism,and gene expression was significantly different compared with the control. Some sequences of different expression fragments were highly homologous to disease-resistant and photosynthesis-associated genes.
Different trials of gum exudation of Elaeagnus angustifolia with different types of wound was done.It was illustrated that more gum could be gotten using the artificial approach making a wound on the mature trunk or on the tree tumor of aged one.Furthermore,the quantity of gum would increase with the increasing of the wound number.
