Transcriptome changes caused by RBP-P mutations in rice seed

Project description:Two RBP-P mutants, P1MH and P3MH, carrying G401S and A252T point mutations, respectively, were obtained by TILLING studies (http://www.shigen.nig.ac.jp/rice/oryzabase). The A252T mutation site in P3MH lies within the linker sequence between the two RRM domains while the G401S substitutions in P1MH is located in the glycine-rich C-terminal region. Those mutations results in varying degrees of reduced RNA binding and/or protein-protein interactive properties of RBP-P. Transcriptome analysis on the dehulled 10-14 days old developing seeds from wild type, P1MH and P3MH mutants indicates that partial loss of RBP-P function caused the differential expression of storage protein genes and relevant genes involved in several essential biological processes during rice development.

Transcriptome changes caused by RBP-L knockdown in rice grains

Project description:A T-DNA insertion within RBP-L 3’UTR resulted in 10-25% expression level of RBP-L gene compared to wild-type. The reduced expression of RBP-L caused partial mis-localization of glutelin and prolamine RNAs and conferred other general growth defects including dwarfism, late flowering and smaller seeds. Transcriptome analysis showed that RBP-L knockdown greatly affected the expression of prolamine family genes and many genes invovled in essential biological pathways during plant development.

Transcriptome changes caused by Tudor-SN mutations in rice seed

Project description:One OsTudor-SN mutant, EM1084, carrying E503K point mutation and one associated WT-OsTSN complemented transgenic (pHL8042/EM1084 ) were applied in this study. EM1084 was obtained by TILLING studies (http://www.shigen.nig.ac.jp/rice/oryzabase). The E503K mutation site in EM1084 lies within the SN3 domain, while the EM1084 complemented transgenic plant was complemented with the full-length WT OsTSN gene driven by native OsTSN promoter. This mutation results in affecting storage protein mRNA localization and, in turn, with a strong reduction in grain weight and storage protein accumulation. Transcriptome analysis on the dehulled 10-14 days old developing seeds from wild type, EM1084 and pHL8042/EM1084 indicates that partial loss of Tudor-SN function caused the differential expression of storage protein genes and relevant genes involved in several essential biological processes during rice development.

Acetylome analyses in the germinating rice seed

Project description:Seed germination is a complicated physiological process, during which structures of mitochondria and plastids are recovered, and metabolisms are re-activated (Han and Yang, 2015). It has been shown that metabolism reactivation is very important for rice germination (He et al., 2011b;Han et al., 2014a). It is still unknown if protein acetylation involved in and regulate these metabolisms during rice seed germination. To answer this question, we globally profiled the acetylome in rice embryos from the germinating seeds. A number of acetylated enzymes were identified. The results provide more information about the metabolism regulation in germinating seeds.

The grain yield modulator miR156 regulates seed dormancy through the gibberellin pathway in rice

Project description:The widespread agricultural problem of pre-harvest sprouting (PHS) could potentially be overcome by improving seed dormancy. Here, we report that miR156, an important grain yield regulator, also controls seed dormancy in rice. We found that mutations in one MIR156 subfamily enhance seed dormancy and suppress PHS with negligible effects on shoot architecture and grain size, whereas mutations in another MIR156 subfamily modify shoot architecture and increase grain size but have minimal effects on seed dormancy. Mechanistically, mir156 mutations enhance seed dormancy by suppressing the gibberellin (GA) pathway through de-represssion of the miR156 target gene Ideal Plant Architecture 1 (IPA1), which directly regulates multiple genes in the GA pathway. These results provide an effective method to suppress PHS without compromising productivity, and will facilitate breeding elite crop varieties with ideal plant architectures.
