Bulked RILs with high and low grain number per panicle derived from 2 cultivars at panicle primordia stage

ABSTRACT: Whole genome transcriptome profiling of bulked RILs with high and low grain number per panicle derived from 2 cultivars at panicle primordia stage The aim of this study was to identify candidate genes responsible for grain number per panicle by combining QTLs analysis with expression analysis. Microarray analysis of RNA extracted from the panicle primordia showed 20 differentially expressed genes, respectively. The differentially expressed genes were shorted to 4 on the basis of their occurance in the QTL region (responcible for grain number regulation) detected in RIL population derived from Pusa 1266 and Pusa Basmati 1. RNA from the stage '0' panicle primordia of 10 RILs with high grain number and 10 with low grain number were bulked and analysed in two different biological replications (A and B) making total four samples

Whole genome transcriptome profiling of Pusa 1266 and Pusa Basmati 1 in panicle primordia stage

Project description:The aim of this study was to identify candidate genes responsible for grain number per panicle between a pair of rice varieties (Pusa 1266 and Pusa Basmati 1) by combining QTL analysis with expression analysis. Microarray analysis of RNA extracted from the panicle primordia showed 2741 differentially expressed genes. The differentially expressed genes were shortened to 18 on the basis of their occurance in the QTL region (responsible for grain number regulation) detected in RIL population derived from Pusa 1266 and Pusa Basmati 1. RNA from the stage '0' panicle primordia of Pusa 1266 and Pusa Basmati 1 were analysed in two different biological replications (A and B) making total four samples

DEG of panicle primordia in ZH11 and OsGATA6-AM lines at the In2 and In3 stages

Project description:To investigate how OsGATA6 regulates heading date, grain number per panicle, and grain phenotypes, we collected panicle primordia of ZH11 and OsGATA6-AM lines at the In2 and In3 stages. We analyzed gene expression using a rice expression profiling chip. Compared with ZH11, OsGATA6-AM lines had 818 up-regulated genes and 284 down-regulated genes

Expression data from OsEBS-transgenic rice B10201 and B10301 and control Guichao2

Project description:In rice (Oryza sativa L.), the number of panicles, spikelets per panicle and grain weight are important components of grain yield. These characteristics are controlled by quantitative trait loci (QTLs) and are derived from variation inherent in crops.The identification of different yield related QTLs facilitates an understanding of the mechanisms involved in cereal crop yield, and may have utility in improving grain yield in cereal crops. an understanding of the mechanisms involved in cereal crop yield, and may have utility in improving grain yield in cereal crops. In the present study, We cloned and characterized a large-panicle QTL, and confirmed that the newly identified gene OsEBS (enhancing biomass and spikelet number) increased plant height, leaf size and spikelet number per panicle, leading to an average of 37.62% increase in total grain yield per plant. trait loci (QTLs) and are derived from variation inherent in crops.

Project description:The aim of the study was to identify candidate genes responsible for drought tolerance trait between a pair of wheat varieties ( WL711 and C306) and correspondng progeny bulks (10 drought susceptible RILs and 10 drought tolerant RILs) by combining QTLs analysis with expression analysis. Microarray analysis of RNA extracted from the flag leaves showed large number of differentially expressed genes. The number of differentially expressed genes was reduced to 37 on the basis of their occurance in a major QTL region (responcible for drought tolerance) detected in RIL population derived from WL711 and C306. RNA from the reproductive stage flag leaf of wheat in irrigated and drought condition of drought susceptible parent WL711, drought tolerant parent C306 and drought susceptible and drought tolerant RIL bulks were analysed in three different biological replications (A , B and C) making total twenty four samples

Down-regulated expression of OsDCL3b affects small RNA biogenesis and panicle development in rice

Project description:Two types of small (18-24 nt) non-coding RNAs (ncRNAs), microRNAs (miRNAs) and small interfering RNAs (siRNAs) have been found to exist widely in higher plants. OsDCL3b has just been reported to process the 24-nt phased small RNAs in rice, which are preferentially expressed in panicle. In this study, we find that down-regulated expression of OsDCL3b leads to lower pollen sterility and seed setting rate, which results in decreased grain yield per plant in rice. Next, small RNA and mRNA sequencing were performed to study the decrease of pollen fertility and seed setting rate. 942 differentially expressed genes were identified, and some of them have already been known to be involved in rice panicle development. Our results indicate that there is a close correlation between small RNA and rice yield.
