Rice xylanase inhibitor RIXI is a XIP-type inhibitor that belongs to the glycoside hydrolase family 18 (GH18), which includes plant class III chitinases (EC 3.2.1.14) known as PR-8 proteins. The aim of this study was to elucidate whether RIXI had any effect on rice endoxylanase and its role(s) in plant defence. RIXI encoding sequence was cloned from rice(More)
In this paper we focus our attention on RIXI, a member of the XIP type xylanase inhibitor proteins in rice. RIXI-overexpression transgenic lines were generated by expressing the RIXI gene under the control of auliflower mosaic virus 35S promoter. In comparison with the wild-type (WT) plants, the transgenic plants had significantly increased levels of RIXI(More)
