Rice(Orvza sativa L.) is one of human’s major food staples,and 1,000-grain weight(TGW) which is determined by grain length,width,thickness and filling rate is a vital component of grain *** identify the genes conditioning this trait and reveal the molecular mechanism of them,we carried out a quantitative trait locus(QTL) mapping with 150 rice recombinant inbred lines(RILs) which were developed from a cross between Nipponbare(japonica,low TGW) and 93-11(indica,high TGW).4.QTLs were detected;two localized on chromosome 5,the other two localized on chromosome 8 and 10,*** we focused on a ma-

A five-gene cluster cvhABCDE was identified from Streptomyces hygroscopicus *** thefirst gene of this cluster,cvhA encoded a putative sensor histidine kinase with a predicted sensor domainconsisting of two trans-membrane segments at the N-terminus and a conserved HATPasecdomain at the *** C-terminus polypeptide of CvhA expressed in Escherichia coli was purified and shown to beautophosphorylated with [γ-32P]ATP in *** phosphoryl group was acid-labile and basic-stable,whichsupported histidine as the phosphorylation *** obvious difference of mycelia development was ob-served between the null mutant of cvhA generated by targeted gene replacement and the wild-type parentalstrain 10-22 grown on solid soya flour medium with 2%-8% glucose or sucrose,but the cvhA mutant couldform much more abundant aerial mycelia and spores than the wild-type strain on solid soya flour mediumsupplemented with 6%-8% mannitol,6%-8% sorbitol,4.-6% mannose,or 4.-6% *** pheno-type was complemented by the cloned wild-type cvhA gene,and no difference was observed for growthcurves of the cvhA mutant and the wild strain in liquid minimal medium with the tested sugars at a concen-tration of 4.,6% and 8%.We thus propose that CvhA is likely a sensor histidine kinase and negativelyregulates the morphological differentiation in a sugar-dependent manner in *** 10-22.

Cotton fibers elongate rapidly after initiation of elongation, eventually leading to the deposit of a large amount ofcellulose. To reveal features of cotton fiber cells at the fast elongation and the secondary cell wall synthesis stages, wecompared the respective transcriptomes and metabolite profiles. Comparative analysis of transcriptomes by cDNA arrayidentified 633 genes that were differentially regulated during fiber development. Principal component analysis (PCA)using expressed genes as variables divided fiber samples into four groups, which are diagnostic of developmental *** grouping results are also found if we use non-polar or polar metabolites as variables for PCA of developingfibers. Auxin signaling, wall-loosening and lipid metabolism are highly active during fiber elongation, whereas cellulosebiosynthesis is predominant and many other metabolic pathways are downregulated at the secondary cell wall synthesisstage. Transcript and metabolite profiles and enzyme activities are consistent in demonstrating a specialization process ofcotton fiber development toward cellulose synthesis. These data demonstrate that cotton fiber cell at a certain stage has itsown unique feature, and developmental stages of cotton fiber cells can be distinguished by their transcript and metaboliteprofiles. During the secondary cell wall synthesis stage, metabolic pathways are streamed into cellulose synthesis.
