(Submitter supplied) The root system is a crucial determinant of plant growth potential because of its important functions, e.g., acquisition of water and nutrients, structural support, and interaction with symbiotic organisms. Elucidating the molecular mechanisms of root development and functions is therefore necessary for improving plant productivity, particularly for crop plants including rice. As an initial step towards developing a comprehensive understanding of the root system, we performed a large-scale transcriptome analysis of the rice root via a combined laser microdissection and microarray analysis approach.

(Submitter supplied) In angiosperms, stigma provides initial nutrients and guidance cues for pollen grain germination and tube growth. However, little is known about genes that regulate these processes in rice. Here we generate rice stigma-specific gene expression profiles through comparing genome-wide expression patterns of hand dissected unpollinated stigma at anthesis with seven tissues including seedling shoot, seedling root, mature anther, ovary at anthesis, seeds of five days after pollination, 10-day-old embryo, 10-day-old endosperm as well as suspension cultured cells by using 57K Affymetrix rice whole genome array. more...

(Submitter supplied) To improve our understanding of soil moisture stress, we performed RNA-Seq analysis using roots from four-week-old rice seedlings grown in soil that had been subjected o drought conditions for 2 to 3 d. From the upregulated genes, we found a T-DNA insertional mutant of rice phytochrome B (OsPhyB) that negatively regulates plant’s degree of tolerance to water deficiencies through its control of ascorbate peroxidase and catalase mediating ROS processing machinery besides the control of total leaf area and stomatal density as previously reported.

(Submitter supplied) Root hairs are an extensive structure of root epidermal cells and are critical for nutrient acquisition, soil anchorage, and environ- mental interactions in sessile plants. The phytohormone ethylene (ET) promotes root hair growth and also mediates the effects of different signals that stimulate hair cell development. However, the molecular basis of ET-induced root hair growth remains poorly understood. more...

(Submitter supplied) Purpose: The root hair is a model for understanding evolution of individual cell differentiation programs in plants. We compare the expression of the genes that participate in root hair development between Arabidopsis and other vascular plants to assess the conservation/diversification of the root hair development programs in vascular plants. Methods: We used RNA-Seq, in triplicates, to measure the genome-wide transcription activity of the root-hair cells isolated by Fluorescence-activated cell sorting (FACS) in Arabidopsis (COBL9::GFP transgeneic line, AtRH) and rice (EXPA30::GFP transgenic line, OsRH). more...

(Submitter supplied) Despite the major physiological dissimilarities between roots and their tips, differences in their gene expression profiles remain largely unexplored. In this research, the transcriptome of rice (Oryza sativa L. subsp. Japonica) mature root tissue and root tips was monitored using mRNA-Seq at 2 time points. Almost 50 million 76 bp reads were mapped onto the rice genome sequence, differential expression patterns between tissues and time points were investigated and at least 1,006 novel transcriptionally active regions (nTARs) were detected to be expressed in rice root tissue. more...

(Submitter supplied) WUSCHEL-related homeobox domain trancription factor WOX11 is a key regulator of crown root growth and development in rice (Oryza sativa. L). However, the gene regulatory network downstream of WOX11 remains largely unknown. To dissect WOX11 transcriptional regulatory framework, we determined the transcriptome of wox11 mutants and corresponding wild type (Hwayoung) by using RNA-seq technology.

(Submitter supplied) How plants determine the final size of growing cells is an important, yet unanswered question. Root hairs provide an excellent model system to study this question since their final cell size is remarkably constant under given environmental conditions. In this study we demonstrate that a trihelix transcription factor GT-2-LIKE1 (GTL1) and its homolog DF1 repress root hair growth in Arabidopsis. Our transcriptional data, combined with genome-wide chromatin binding data, show that GTL1 and DF1 directly bind the RSL4 promoter and regulate its expression to repress root hair growth. more...
