Project description:As a species mostly planted in tropical and subtropical regions, rice is sensitive to chilling temperature, especially at reproductive stage. However, the effect of low temperature on seed development has not been well characterized. The transcriptome of two rice cultivars Zhonghua11 and Hanfeng were analyzed to characterize the gene regulatory networks of rice seed during low temperature treatment.

Project description:The genome-wide transcriptome analyses using microarray probes containing genes and repeat sequences have been performed to examine response to the low-temperature in rice. We have particularly focused on the rice anther at the booting stage, since the low-temperature at this stage resulted in pollen abortion. The results demonstrated that the low-temperature stress caused genome-wide changes of transcriptional activities not only in genes, but also in repeat sequences of the rice anther. The degrees of the temperature responsive changes varied among the rice strains.

However, the effect of low temperature on seed development has not been well characterized. The transcriptome of two rice cultivars Zhonghua11 and Hanfeng were analyzed to characterize the gene regulatory networks of rice seed during low temperature treatment. Whole plants of two rice cultivars Zhonghua11 (low temperature sensitive) and Hanfeng (low temperature tolerance) were treated at 14°C for 2 days during seed development stage. The plants without treatment serve as controls. Rice seeds were harvested for RNA extraction.

The results demonstrated that the low-temperature stress caused genome-wide changes of transcriptional activities not only in genes, but also in repeat sequences of the rice anther. The degrees of the temperature responsive changes varied among the rice strains. The five rice strains exposed to the low temperature at 12°C for four days, were used for the microarray analyses. RNA was extracted from the anthers one day (C1), three days (C3) and five days (C5: this is one day after completion of the cool treatment) after the cool treatment and non-treated anthers (C0) with three biological replicates.

Project description:Temperature-sensitive male sterility is one of the core components for hybrid rice breeding based on two-line system. We previously found that knockout of ARGONAUTE 1d (AGO1d) caused temperature-sensitive male sterility in rice by influencing phased small interfering RNA (phasiRNA) biogenesis and function. However, the specific phasiRNAs and their targets underlying the temperature-sensitive male sterility in ago1d mutant remain to be determined. Here, we demonstrate that the ago1d mutant displays normal female fertility but complete male sterility at low temperature. Through a multi-omics analysis of small RNA, degradome, and transcriptome, we found that 21-nt phasiRNAs account for the greatest proportion of the 21-nt small RNA (sRNA) species in rice anthers and are sensitive to low temperature and markedly down-regulated in ago1d mutant. Moreover, we found that 21-nt phasiRNAs are essential for the mRNA cleavage of a set of fertility- and cold tolerance-associated genes, such as EDT1, TDR, OsPCF5 and OsTCP21, directly or indirectly determined by AGO1d-mediated gene silencing. The loss-of-function of 21-nt phasiRNAs can result in up-regulation of their targets and causes varying degrees of defects in male fertility and grain setting. Our results highlight the essential functions of 21-nt phasiRNAs in temperature-sensitive male sterility in rice and suggest their promising application in two-line hybrid rice breeding in the future.

Project description:Higher temperature conditions during the final stages of rice seed development (seed filling and maturation) are known to cause damage to both rice yield and rice kernel quality. Japan, especially western and central parts, has seen record high temperatures in the last decade, and the rice kernel quality has decreased; specifically a reduction the first-grade of rice has been seen. In this study, we specifically looked at the harvested rice in a town of the central Kanto-plains (Japan) during the year 2010, which saw day-time temperatures go above the critical limits ranging from 34 to 38C at the final stages of seed development and maturity to investigate high-temperature effects in the actual field condition. Three sets of dry mature rice seeds (commercial) were obtained Japan Agriculture (JA Zen-Noh) branch in Ami-town of Ibaraki prefecture in September 2010, as grade 1 (labeled as Y1), grade 2 (labeled as Y2), and grade 3 (out-of-grade, labeled as Y3). The research objective was to examine in particular alterations in gene expressions genome-wide in grade 2 (Y2) and grade 3 (Y3) seeds over the grade 1 (Y1) following the high-temperature spike using a high-throughput omic-approach DNA microarray (Agilent 4 x 44K rice oligo DNA chip) in conjunction with MapMan bioinformatics analysis. Rice seed quality analysis revealed, as expected, low quality in Y3 > Y2 over Y1, in taste, amylose, protein and fatty acid degree, but not in water content. Transcriptome profiling data revealed 124 and 373 up-regulated and 106 and 129 down-regulated genes in Y2 and Y3, respectively. Bioinformatics analysis of differentially expressed genes revealed changes in function of genes related to metabolism, including starch metabolism (e.g., alpha amylase), defense/stress response, fatty acid biosynthesis and hormones. This research provides for the first time the seed transcriptome profile for the classified low grades (2 and out-of-grade) of rice under an actual stressed environmental condition of high temperature.

Project description:Low temperature is one of the major abiotic stresses limiting rice growth and productivity, it is urgent to reveal the genetic and molecular mechanisms of plant responses to low temperature stress and to search for useful genetic resources for improving low-temperature tolerance. the 8 accessions from China Core Collection include 4 cold tolerance accessions, 3 sensitivity accessions and 1 intermediate type accession. We used microarrays to detail variation of the gene expression after cold treatment and screen more cold-response genes in rice.
