Os06g0254700 encode a caleosin

Annotated Information

Function

Os06g0254700 is a stress responsive gene. It encodes the caleosin which mainly lay in oil body or lipid body.These physiological and biochemical processes including regulation of genes involvedin stomatal closure, maintaining internal and external balance of water and ions,adjusting the synthesis and catabolism.Caleosins not only promote formation of oil body but also is related to drought stress.

Expression

It is located on chromosome 6.There are two other caleosin genes-Os06g0254300 and Os06g0254600 in chromosome 6.These three genes get together because tandem duplication.Caleosins have a significant feature that EF-hand domain in N-terminal can combine Ca2+,a central hydrophobic region and a security protein kinase phosphorylation sites in C-terminal.Caleosins's N-terminal and C-terminal are located in the cytoplasm,however central hydrophobic region are anchored in the phospholipid monolayer membrane.

Evolution

Six caleosin genes in rice distribute on four different chromosomes.Os06g0254300,Os06g0254600, OsCLO-6 three genes are located to adjacent position of chromosome 6.Homology of Os06g0254300 and Os06g0254600reach to 92%,Os06g0254600 and Os06g0254700 is 49%.Indicating that Os06g0254300 and Os06g0254600 originated in a close repeated events, but Os06g0254700 and Os06g0254600 repeated earlier.Excavations and research in arid pathway for in-depth understand the mechanisms of plant drought, reducing the effects of drought, etc,are great significance Os06g0254700 contains introns,it is described Os06g0254700 is not originated in retrotransposition events. You can also add sub-section(s) at will.
