Genes expressed in sugarcane maturing internodal tissue



Genes expressed in sugarcane maturing internodal tissue



Plant cell reports 20(11): 1075-1081



To explore gene expression during sugarcane culm maturation, we performed a partial sequence analysis of random clones from maturing culm total and subtracted cDNA libraries. Database comparisons revealed that of the 337 cDNA sequences analysed, 167 showed sequence homology to gene products in the protein databases, while 111 matched uncharacterised plant expressed sequence tags (ESTs) only. The remaining cDNAs showed no database match and could represent novel genes. The majority of ESTs corresponded to a variety of genes associated with general cellular metabolism. ESTs homologous to various stress response genes were also well represented. Analysis of ESTs from the subtracted library identified genes that may be preferentially expressed during culm maturation. This research has provided a framework for functional gene analysis in sugarcane sucrose-accumulating tissues.
