5.6.2.7 additional information TCD33 encodes a chloroplast-located DEAD-box RNA helicase protein. Rice thermo-sensitive chlorophyll-deficient mutant, tcd33, displays an albino phenotype before the four-leaf stage, then withers and eventually dies at 20°C, while wild-type plants exhibit normal green coloration at 32°C. The tcd33 seedlings also exhibit less chlorophyll contents and severe defects of chloroplast structure under 20°C condition. The transcript expression level of TCD33 indicates that the genes related to chlorophyll (Chl) biosynthesis, photosynthesis, and chloroplast development in tcd33 mutants are downregulated at 20°C, but are nearly recovered to or slightly higher than wild-type level at 32°C Oryza sativa Japonica Group

5.6.2.7 evolution phylogenetic analysis shows that the evolutionary relationships of TCD33 homologues are consistent with the taxonomy Oryza sativa Japonica Group
5.6.2.7 malfunction tcd33 mutants that lost the two conserved domains DEXDc and HELICc, show an incompleteness of the three-dimensional structure. Reduced chlorophyll contents and albino phenotype in tcd33 mutants. Cold stress alters genetic regulation of the chlorophyll development and the involved gene expressions, overview. Lack of TCD33 function affects the transcripts of associated genes Oryza sativa Japonica Group
5.6.2.7 additional information TD33 contains two conserved domains, DEXDc and HELICc, characteristics of the DEAD-box protein family Oryza sativa Japonica Group
5.6.2.7 physiological function DEAD-box RNA helicase TCD33, a cold-inducible enzyme, is essential for early chloroplast development and is important for cold-responsive gene regulation and cold tolerance in rice. TCD33 is essential in the whole process of chloroplast development Oryza sativa Japonica Group
