A cDNA encoding a novel cysteine proteinase inhibitor (CPI) was isolated from a gland mutant Xiangmian-18 of upland cotton during the pigments gland forming stage. The cDNA comprises 378 bp and encodes 125 amino acid residues with molecular mass of 13.8 kDa. It contains the conserved motif of cysteine protease inhibitors and belongs to the cystatin superfamily (Gln- Val-Val-Ala-Gly). The deduced amino acid sequences of the domains are highly similar to the normal upland cotton (96.8%). SDS-PAGE and western hybridization analysis showed that the expressed recombinant protein was recombinant CPI. The inhibitory activity of recombinant CPI was 46 u/μg which was measured by inhibiting the protease activity of papain. RT-PCR results indicated that the expression level of developing gland stage was higher than that of undeveloped gland stage.

The pigment gland is an important character of the Gossypium plant. With the aim of identifying genes involved in pigment gland morphogenesis in cotton, gene expression during pigment gland morphogenesis in Chuan 2802, which is glanded both in seed and plant, and a glandless line N5 was profiled using Affymetrix Cotton microarray. The results showed that there were 564 differentially expressed genes greater than twofold during gland morphogenesis. About 60.2% of these genes shares similarity with known genes on GenBank and about 39.8% with no functional description in the database. These described genes may play roles in defense response, response to oxidative stress, peroxidase activity, and the other metabolic pathways. The KEGG Orthology-Based Annotation System indicated that these above twofold expressed genes involved seven biochemical pathways on KEGG. These findings suggest that a complicated regulation is associated with pigment gland morphogenesis and the associated defense response including gossypol biosynthesis in cotton.
