Temporal analysis of mRNA from panicle tissue from field grown rice under high nighttime temperatures

ABSTRACT: A IR64 variety of rice was grown in a field plot at the International Rice Research Institute (IRRI) in the Philippines. The data gained from the experiment provides information of the daily transcriptional changes occur in panicle tissue during an important developmental period under control and warm night temperatures.

ABERRANT PANICLE ORGANIZATION2 controls multiple steps in panicle formation through common direct-target genes

Project description:At the transition from vegetative to reproductive growth in rice, a developmental program change occurs, resulting in panicle (rice inflorescence) formation. The initial event of the transition is the change of the shoot apical meristem (SAM) to an inflorescence meristem (IM), accompanied by a rapid increase in the meristem size. Suppression of leaf growth also occurs, resulting in the formation of bracts. The IM generates branch meristems (BMs), indeterminate meristems that reiteratively generate next-order meristems. All meristems eventually acquire a determinate spikelet meristem identity and terminate after producing a floret. ABERRANT PANICLE ORGANIZATION2 (APO2) is the rice ortholog of Arabidopsis (Arabidopsis thaliana) LEAFY (LFY), a plant-specific transcription factor. APO2 is a positive regulator of panicle branch formation. Here, we show that APO2 is also required to increase the meristem size of the IM and suppress bract outgrowth. We identified genes directly and indirectly regulated by APO2 and identified APO2-binding sites by ChIP-seq analysis. These analyses showed that APO2 directly controls known regulators of panicle development, including SQUAMOSA PROMOTER BINDING PROTEIN LIKE14 and NECK LEAF1. Furthermore, we revealed that a set of genes act as downstream regulators of APO2 in controlling meristem cell proliferation at the reproductive transition, bract suppression, and panicle branch formation. Our findings indicate that APO2 acts as a master regulator of rice panicle development by regulating multiple steps in the reproductive transition through directly controlling a set of genes.

Genome-wide temporal-spatial gene expression profiling of drought responsiveness in rice

Project description:Rice is highly sensitive to drought, and the effect of drought may vary with the different genotypes and development stages. Genome-wide gene expression profiling was used as the initial point to dissect molecular genetic mechanism of this complex trait and provide valuable information for the improvement of drought tolerance in rice. Affymetrix rice genome array containing 48,564 japonica and 1,260 indica sequences was used to analyze the gene expression pattern of rice exposed to drought stress. The transcriptome from leaf, root, and young panicle at three developmental stages was comparatively analyzed combined with bioinformatics exploring drought stress related cis-elements. In this study, the gene expression patterns across six tissues including leaves and roots at tillering stage and panicle elongation stage, leaves and young panicle at booting stage ( TL: leaves at tillering stage; TR: roots at tillering stage; PL: leaves at panicle elongation stage; PR: roots at panicle elongation stage; BP: young panicle at booting stage; BL: leaves at booting stage) were characterized by using the Affymetrix rice microarray platform based on a drought tolerant rice line derived from IR64.

Dynamic profile of gene expression in rice panicle of post-meiosis under high temperature

Project description:To comprehend the gene expression profile in rice panicle under high temperature, Agilent 4×44k rice oligo microarray experiments were carried out using rice panicle of post-meiosis at 0 min, 10min, 20 min, 60 min, and 2 hr after the treatment of 40 degree centigrade, and the differentially expressed genes at the time course were involved in binding, catalysis, stress response, and cellular process. The significantly expressed genes were mainly up-regulated. Among HR genes, the predominant transcription factor gene families were Hsf, NAC, AP2/ERF, WRKY, MYB, and C2H2. The MapMan analysis demonstrated that, under heat treatment, the HR genes were enriched in the pathways related to biotic stress, abiotic stress including heat and cold, and cell cycle and development, ubiquitin-proteasome , lipid and secondary metabolisms, which revealed the great importance of cross-talk and protein homeostasis in response to heat in rice panicle of post-meiosis.

Transcriptome dynamics of rice spikelets under heat stress treatment

Project description:Rice reproductive development is highly sensitive to high temperature stress. In rice flowering occurs over a period of at least 5 days. Heat stress alters the global gene expression dynamics in panicle especially during pollen development, anthesis and grain filling. Some of the rice genotypes like Nagina 22 show better spikelet fertility and grain filling compared to high yielding and popular rice cultivars like IR 64. We carried out microarray analysis of 8 days heat stressed panicles of Nagina22, heat and drought tolerant aus rice cultivar and IR64, a heat susceptible indica genotype along with unstressed samples of Nagina22 and IR64 so as to understand the transcriptome dynamics in these two genotypes under heat stress and to identify the genes important for governing heat stress tolerance in rice.

Changes in rice NILs panicle expression profile in response to drought stress at reproductive stage

Project description:The current knowledge of drought stress transcriptomes in rice are mostly relying on comparative studies of diverse genetic background under drought. A more reliable approach is to use near-isogenic lines (NILs) with a common genetic background (Donar parent: Aday Sel, Recurrent parent: IR64), but contrasting levels of resistance to drought stress under initial exposure to water deficit. Here, we examined two pairs of NILs in IR64 background with contrasting drought tolerance. We obtained gene expression profile in panicles of rice NILs under different levels of drought stress help to identify genes and mechanisms involved in drought stress.
