Project description:To examine the role of formation of a strong sink during leaf senescence, we compared the expression profile of the flag leaf of three different sterile mutant lines with fertile plants. The fertile and sterile lines showed basically similar expression profiles of flag leaves sampled at the same time. However, the fertile lines showed more rapid and enhanced change in transcriptome as compared to the sterile lines indicating that leaf senescence initiated independent of sink formation and is accelerated by sink formation.

Project description:To examine the role of formation of a strong sink during leaf senescence, we compared the expression profile of the flag leaf of three different sterile mutant lines with fertile plants. The fertile and sterile lines showed basically similar expression profiles of flag leaves sampled at the same time. However, the fertile lines showed more rapid and enhanced change in transcriptome as compared to the sterile lines indicating that leaf senescence initiated independent of sink formation and is accelerated by sink formation. Three independent mutant lines, namely, pair1, pair2, and mel1-1, and fertile plants (homozygous or heterozygous) derived from each segregating population were used for comparison. The flag leaves were sampled at initiation of heading, 1 week after heading (WAH), 2 WAH, and 3 WAH, with three biological replicates.

Project description:Nongken 58S is photoperiod-sensitive genic male sterile (PGMS) rice. Its pollens are fully sterile when it is treated with LD condition from glume primordium differentiation stage to pistil/stamen primordium forming stage, and its pollens are fertile when treated with SD condition during these stages. We used microarrays to detail the global programme of leaf gene expression under LD and SD condition for investigating the transcriptomes in the male sterility transition in PGMS rice to find out the genes related to this transition

Project description:To comprehend the gene expression profile in rice flag leaf under high temperature, Agilent 4×44k rice oligo microarray experiments were carried out using rice flag leaf of reproductive stage at 0 min, 20 min, 60 min, 2 hr, 4 hr, and 8 hr after the treatment of 40 degree centigrade, and the significantly expressed genes mainly involved in transcriptional regulation, transport, protein binding, antioxidant, and stress response were identified. Among them, the predominant transcription factor gene families were Hsf, NAC, AP2/ERF, WRKY, MYB, and C2H2. KMC analysis discovered the time-dependent gene expression pattern under heat. The metabolism pathway analysis demonstrated that, under heat treatment, glycolysis and ubiquitin-proteasome was enhanced, and TCA, gluconeogenesis, the secondary metabolism and light-reaction in the photosystem was dramatically repressed, which revealed the great importance of maintaining primary metabolism and protein homeostasis in response to heat in rice flag leaf.

Project description:Plant diurnal oscillation is a 24-hour period based variation. The correlation between diurnal genes and biological pathways was widely revealed by microarray analysis in different species. Rice (Oryza sativa) is the major food staple for about half of the world's population. The rice flag leaf is essential in providing photosynthates to the grain filling. However, there is still no comprehensive view about the diurnal transcriptome for rice leaves. In this study, we applied rice microarray to monitor the rhythmically expressed genes in rice seedling and flag leaves. We developed a new computational analysis approach and identified 6,266 (10.96%) diurnal probe sets in seedling leaves, 13,773 (24.08%) diurnal probe sets in flag leaves. About 65% of overall transcription factors were identified as flag leaf preferred. In seedling leaves, the peak of phase distribution was from 2:00am to 4:00am, whereas in flag leaves, the peak was from 8:00pm to 2:00am. The diurnal phase distribution analysis of gene ontology (GO) and cis-element enrichment indicated that, some important processes were waken by the light, such as photosynthesis and abiotic stimulus, while some genes related to the nuclear and ribosome involved processes were active mostly during the switch time of light to dark. The starch and sucrose metabolism pathway genes also showed diurnal phase. We conducted comparison analysis between Arabidopsis and rice leaf transcriptome throughout the diurnal cycle. In summary, our analysis approach is feasible for relatively unbiased identification of diurnal transcripts, efficiently detecting some special periodic patterns with non-sinusoidal periodic patterns. Compared to the rice flag leaves, the gene transcription levels of seedling leaves were relatively limited to the diurnal rhythm. Our comprehensive microarray analysis of seedling and flag leaves of rice provided an overview of the rice diurnal transcriptome and indicated some diurnal regulated biological processes and key functional pathways in rice.

Project description:Investigation of comprehensive gene expression level changes in male strobili of sterile mutant, compared to the fertile plant. We designed a new custum array derived from ESTs of Cryptomeria japonica for this study. Male strobili of C. japonica were collected from Toyama 1 half-sib F2 pedigree. Toyama 1 male-sterile mutant was first reported in Saito, M. , H. Taira, and Y. Furuta (Journal of Forest Research 3(3):167-173). Microarray studies using both individual samples and pooled samples were performed. Total RNA was extracted from male strobili at four developmental stages derived from each seven fertile and male-sterile trees as individual samples. Pooled RNA samples were prepared from four to eight different fertile and sterile plants at three developmental stages.
