Abstract

Cellulose synthase (CESA) synthesizes cellulose for plant cell walls and determines plant morphology and biomass amount. The recently sequenced cotton genomes of two diploid species, Gossypium raimondii and G. arboreum have become references for study of agriculturally important cotton fibers composed nearly exclusively of cellulose. To better understand the roles of functionally divergent CESAs, we compared physical properties and CESA expression patterns from various tissues at different developmental stages of the two diploid cottons. Chemical and phenotypic analyses showed that the domesticated G. arboreum fibers with high cellulose content, thick cell wall, and long length were superior to the wild G. raimondii fibers. Among the seventeen orthologous CESA pairs sharing > 98% identity between the two diploid genomes, putatively nonfunctional CESAs lacking structural integrity or conserved catalytic motifs were identified. Transcript expression patterns of functional CESA family genes sharing high sequence similarities in each genome were determined by RNA-seq and a PCR method that distinguished specific CESAs based on single nucleotide polymorphisms. Our results showed that mutational events causing non-functionalization and tissue specific expression patterns of the redundant CESA genes occurred in the domesticated G. arboreum more frequently than the wild G. raimondii. The results provide insight on how cellulose biosynthesis has been altered during diploid cotton evolution and domestication process, and contributed to the diversity of cotton species that differ in fiber quality and cellulose content.
