[Method] According to the EST se- quence of cysteine proteinase inhibitor in constructed SSH snhtraetive library of seedless litchi abortion, nucleotide sequence of the cysteine proteinase inhibitor gene was obtained by using RACE technology and analyzed by using bioinformatics software. [ Result ] A cysteine protease inhibitor gene was obtained with the sequence of 635 bp containing a 321 bp open reading frame. It was predicted that the erlcoded protein contained 106 amino acids with conserved domain of cysteine proteinase inhibitor and had relatively high homology with the cysteine proteinase inhibitor gene of several species, [ Conclusion] This study laid the foundation for further ex- ploring the physiological functions of this cysteine proteinase inhibitor gene in plants.展开更多
