Laboratory Introduction
-
Function of hydrogen peroxide-regulated small RNAs in rice. Rice, a major grain crops in the world, is grown in the field, and is always exposed to various environmental stresses. The stress environment induces plant to produce reactive oxygen species (ROS), including H2O2 . The appropriate concentration of H2O2 acts as a signal messenger, while the excessive ROS causes the oxidative stress and cell death. Hence, this research is to study the functions of H2 O2-related small RNAs and their target genes in rice. Small RNA sequencing and degradome sequencing were already used to screen H2O2-related small RNAs and their target genes. Further through the information of microarray from rice treated with H2O2, several miRNA/target modules were selected. The quantitative RT-PCR and agroinfiltration were used to confirm the relationship between small RNAs and their targets. This study may elucidate the functions of H2O2-related miRNAs and their target genes in rice, and can be further applied to increase the tolerance of rice under environmental stresses.

Isolation and characterization of small RNAs and genes regulated by systemic wounding in sweet potato. Plants have developed defense systems responding to external attacks in order to survive from herbivores. After wounding, the leaves physically wounded are called local leaves, and the leaves, which are not wounded but in the same plant, are named systemic leaves. The mechanism regulated by the systemic leaves in sweet potato after wounding is under studied. The expression of peptide hormone gene preproHypSys is induced in sweet potato after wounding and its processing product Hydroxyproline-rich glycopeptides (HypSys) is able to stimulate the systemic effect over all the plant. Transgenic sweet potato overexpressing preproHypSys has been constructed, and is able to provoke very strong systemic signal after wounding. Therefore, this transgenic sweet potato is an excellent material to investigate systemic wounding effect. The results of this study may uncover the regulation network of systemic wounding, and may facilitate plants to survival from herbivore attack.
