Polyploidized Rice Improves Plant Height and Yield through Regulating Expression of Yield Related Genes.

Project description:Polyploidization is one of the effective ways to improve plant height and yield of rice (Oryza sativa L.). However, the molecular mechanism of regulation is not yet fully understood. Here, we investigated the agronomic traits of diploid (Balilla-2x) and tetraploid (Balilla-4x) of japonica rice variety Balilla. Compared with Balilla-2x, Balilla-4x exhibited significantly increased plant height, spike length and yield per plant. RNA-seq analysis of the leaves of Balilla-2x and Balilla-4x was performed and the results showed that the expression levels of yield related genes (e.g., STH1, OsYUC9, and OsDEP1) were significantly upregulated in Balilla-4x rice plants, these genes are related to plant height and panicle development. These results indicated that polyploidization changed the expression of genes related to agronomic traits such as plant height and spike length, thereby increasing rice yield. This study provides a further basis for understanding the yield of rice after polyploidization, and can serve as a new theoretical reference for breeding high-yielding rice varieties achieved.

The identification and characterization of a plant height and grain length related gene hfr131 in rice

Project description:Plant height and grain size are important agronomic traits affecting rice yield. Various plant hormones participate in the regulation of plant height and grain size in rice. However, how these hormones cooperate to regulate plant height and grain size is poorly understood. In this study, we identified a brassinosteroid-related gene, hfr131, from an introgression line constructed using Oryza longistaminata, that caused brassinosteroid insensitivity and reduced plant height and grain length in rice. Further study showed that hfr131 is a new allele of OsBRI1 with a single-nucleotide polymorphism (G to A) in the coding region, leading to a T988I conversion at a conserved site of the kinase domain. An auxin response factor, OsARF17, could bind to the promoter region of HFR131 and positively regulated HFR131 expression, thereby regulating the plant height and grain length, and influencing brassinosteroid sensitivity. Haplotype analysis showed that the consociation of OsAFR17Hap1/HFR131Hap6 conferred an increase in grain length. Overall, this study identified hfr131 as a new allele of OsBRI1 that regulates plant height and grain length in rice, revealed that brassinosteroid and auxin might coordinate through OsARF17–HFR131 interaction, and provided a potential breeding target for improvement of rice yield.

Enhanced sucrose loading improves rice yield by increasing grain size

Project description:Transgenic rice plants expressing the Arabidopsis phloem-specific sucrose transporter AtSUC2, which loads Suc into the phloem, showed an increase in grain yield of up to 16% relative to wild-type plants in field trials. The goal was to reveal how expressed AtSUC2 in rice leads to increased grain yield analyzing global gene expression.

OsMPH1 regulates plant height and improves grain yield in rice.

Project description:Plant height is a major trait affecting yield potential in rice. Using a large-scale hybrid transcription factor approach, we identified the novel MYB-like transcription factor OsMPH1 (MYB-like gene of Plant Height 1), which is involved in the regulation of plant height in rice. Overexpression of OsMPH1 leads to increases of plant height and grain yield in rice, while knockdown of OsMPH1 leads to the opposite phenotypes. Microscopy of longitudinal stem sections indicated that a change in internode cell length resulted in the change in plant height. RNA sequencing (RNA-seq) analysis of transgenic rice lines showed that multiple genes related to cell elongation and cell wall synthesis, which are associated with plant height and yield phenotypes, exhibited an altered expression profile. These results imply that OsMPH1 might be involved in specific recognition and signal transduction processes related to plant height and yield formation, providing further insights into the mechanisms underlying the regulation of plant height and providing a candidate gene for the efficient improvement of rice yield.

Spatiotemporal resolved leaf angle establishment improves rice grain yield via controlling population density [mRNA]

Project description:Leaf angle is mainly determined by the lamina joint (LJ), and contributes to ideal crop architecture for high yield. Here, we dissected five successive stages with distinct cytological features of LJs spanning organogenesis to leaf angle formation, and obtained the underlying stage-specific mRNAs and small RNAs, which well explained the cytological dynamics during LJ organogenesis and leaf angle plasticity. Combining the gene coexpression correlation with high-throughput promoter analysis, we identified a set of transcription factors determining the stage- and/or cytological structure-specific profiles. The functional studies of these TFs demonstrated that cytological dynamics determined leaf angle, and the knockout rice of these TFs with erect leaves significantly enhanced yield by maintaining the proper tiller number under dense planting. This work revealed the high-resolution mechanisms how the cytological dynamics of LJ determined the leaf erectness, and served as a valuable resource to remodel rice architecture for high yield via controlling population density.

Ef-cd locus shortens rice maturity duration without yield penalty

Project description:The contradiction between ‘high-yielding’ and ‘early-maturing’ hampers further improvement on annual rice yield. Here we reported the positional cloning of a major maturity duration-regulatory gene, Early flowering-completely dominant (Ef-cd), and demonstrated that natural variation in Ef-cd could be used to overcome the above contradictory. The Ef-cd locus gives rise to a long noncoding RNA (lncRNA) antisense transcript overlapping the OsSOC1 gene. Ef-cd lncRNA expression positively correlates with the expression of OsSOC1 and H3K36me3 deposition. Field test comparisons of early-maturing Ef-cd near-isogenic lines (NILs) with their wild types as well as the derivative early-maturing hybrids with their wild-type hybrids conducted under different latitudes determined that early-maturing Ef-cd allele shortens maturity duration (ranging from 7 to 20 days) without a concomitant yield penalty. Ef-cd facilitates nitrogen utilization and also improves the photosynthesis rate. Analysis of 1,439 elite hybrid rice varieties revealed that the 16 homozygotes and 299 heterozygotes possessing Ef-cd matured significantly earlier. Therefore, Ef-cd could be a vital contributor of elite early-maturing hybrid varieties in balancing grain yield with maturity duration.
