Project description:The leptotene-zygotene transition is a major step in meiotic progression during which pairing between homologous chromosomes is initiated and double strand breaks occur. OsAM1, a homolog of maize AM1 and Arabidopsis SWI1, encodes a protein with a coiled-coil domain in its central region that is required for the leptotene-zygotene transition during rice meiosis. To gain more insight into the role of OsAM1 in rice meiosis and to identify additional meiosis-specific genes, we characterized the transcriptomes of young panicles of Osam1 mutant and wild-type rice plants using RNA-Seq, bioinformatic and statistical analyses. As a result, a total of 25,750 and 28,455 genes were expressed in young panicles of wild-type and Osam1 mutant plants, respectively, and 4,400 differentially expressed genes (DEGs; log2 Ratio ≥ 1, FDR ≤ 0.05) were identified. Of these DEGs, four known rice meiosis-specific genes were detected, and 22 new putative meiosis-related genes were found by mapping these DEGs to reference biological pathways in the KEGG database. We identified eight additional well-conserved OsAM1-responsive rice meiotic genes by comparing our RNA-Seq data with known meiotic genes in Arabidopsis and fission yeast. We sequenced the transcriptome of young panicles of Osam1 mutant and wild-type rice.

Project description:One-step and two-step pathways are proposed to synthesize cytokinin. One-step pathway is mediated by LONELY GUY (LOG) proteins. However, the enzyme for two-step pathway has not been identified yet. Here, we show that a QTL GY3 boosts grain yield by more than 20% via manipulating two-step pathway. GY3 encodes a LOG protein that acts as a 5’-ribonucleotide phosphohydrolase by excessive consuming the cytokinin precursors, which contrasts with the activity of canonical LOG members as phosphoribohydrolases in a one-step pathway. The residue S41 of GY3 is crucial for the dephosphorylation of iPRMP. A solo-LTR insertion within the promoter of GY3 suppressed its expression and resulted in a higher content of active cytokinins in young panicles. Introgression of GY302428 increased grain yield per plot by 7.4% to 16.3% in all investigated indica backgrounds both under long-day and short-day conditions, which demonstrates the great value of GY302428 in indica rice production.

Project description:Here, we first reported the construction of a phosphoproteomic landscape of 6 tissues, including callus, leaves, roots, shoot meristem (SM), young panicles (YP) and mature panicles (MP), from Nipponbare (Oryza sativa ssp. japonica). By employing a non-gel, quantitative phosphoproteomic approach, a total of 4792 phosphopeptides from 2657 phosphoproteins were identified, which were found to be differentially phosphorylated among tissues.

Project description:The effect of light during the development of freezing tolerance was studied in winter wheat (Triticum aestivum L. var. Mv Emese) and spring wheat variety Nadro. Ten-day-old plants were cold hardened at 5°C for 12 days either under normal (250 mmol m-2 s-1) or low light (20 mmol m-2 s-1) conditions.

Project description:Leaves and panicles from recurrent parent KMR3 and a high yielding KMR3-O.rufipogon introgression line were used Microarray analysis was carried out to reveal up- and down-regulated DEGs in leaves and panicles of control and experimental line for identifying key genes that help improve yield Leaves and fully emerged young panicles from both lines were used for RNA extraction and hybridization on Affymetrix microarrays
