Analysis of rice roots and leaves 30 and 120 minutes after treatment with the cytokinin trans-zeatin (tZ). Cytokinins (CKs) are a class of plant hormones that regulate the growth and development of plants. Results provide insight into the molecular mechanisms regulated by CK in rice.

(Submitter supplied) Cytokinins (CKs) are a class of plant hormones that regulate many aspects of growth and development, including cell division, apical dominance, leaf senescence, nutrient signaling, and shoot differentiation. In the past decade, substantial progress has been made in understanding CK biosynthesis, metabolism and signal transduction. Much of this knowledge is based on research in Arabidopsis, a dicotyledonous model plant. more...

(Submitter supplied) Glycinebetaine-induced water-stress tolerance in codA-expressing transgenic indica rice is associated with up-regulation of several stress responsive genes. Rice (Oryza sativa L.), a non-accumulator of glycinebetaine (GB), is highly susceptible to abiotic stress. Transgenic rice with chloroplast-targeted choline oxidase encoded by the codA gene from Arthrobacter globiformis has been evaluated for inheritance of transgene up to R5 generation and water-stress tolerance. more...

(Submitter supplied) Oryza sativa cv. Nipponbare was engineered to over-express a barley alanine aminotransferase (alaAT) gene using the promoter (OsANT1) from a rice aldehyde dehydrogenase gene that expresses in roots. We are using biotechnology to improve the nitrogen use efficiency of rice by over-expressing alaAT in a tissue specific (root) manner. The AlaAT enzyme is a reversible aminotransferase that is linked to both C and N metabolism since it uses pyruvate plus glutamate to produce alanine and 2-oxoglutarate, and visa versa.

(Submitter supplied) We generated more than 23,000 independent Arabidopsis transgenic lines that expressed rice fl-cDNAs (Rice FOX Arabidopsis lines). The short generation time and rapid and efficient transformation frequency of Arabidopsis enabled the functions of the rice genes to be analyzed rapidly. We screened rice FOX Arabidopsis lines for alterations in morphology, photosynthesis, element accumulation, pigment accumulation, hormone profiles, secondary metabolites, pathogen resistance, salt-tolerance, UV signaling, high light tolerance, and heat stress tolerance. more...

(Submitter supplied) We found that Arabidopsis plants constitutively expressing OsRR6 exhibit reduced cytokinin sensitivity, adventitious root formation and enhanced anthocyanin accumulation. In addition they are hypersensitive to red, far-red and blue light in hypocotyl growth assay and also flower little early as compared to wild type.Therefore, to identify the downstream pathways affected in the OsRR6 overexpression plants, we performed transcriptome profiling of overexpression line vs wild type using Affymetrix microarray platform.

(Submitter supplied) 30 collars were taken from wild type plants or antiOsLIC transgenic plants respectively. One collar from one plant only. The leaves are just sprout 2-3 cm (about 1-2 days) from the stem. For measuring the genes expression level, Wild type plants were taken as control. The developing collar from both line2 of OsLIC antisense transgenic plants and wild type were harvested at the heading stage. The position of the collar was about 1cm above the last developed collar. more...

(Submitter supplied) Drought, salinity and sub-optimal temperatures are stresses that cause adverse effects on the growth of plants and the productivity of crops. In this study, we have analyzed the expression profiles of rice genes under control and abiotic stress conditions using microarray technology to identify the genes differentially expressed during various abiotic stresses.

(Submitter supplied) Plants initially undergo a period of vegetative development, in which it produces leaves from shoot apical meristem (SAM) and roots from the root apical meristem. Later in development, the SAM undergoes a change in fate and enters reproductive development called as floral transition, producing flowers and seeds. Our understanding of the molecular and genetic mechanisms that underlie reproductive development in plants has increased tremendously in the past decade, essentially through the work on Arabidopsis. more...

Seedlings were incubated in 0.1% dimethyl sulfoxide (control) or 50 micromolar solutions of indole-3-acetic acid (IAA treatment) and benzyl aminopurine (BAP treatment) for 1h and 3h. Equal amounts of 1h and 3h samoles were pooled for each treatment before RNA isolation. more...

(Submitter supplied) We investigated changes in gene expression in rice plants exposed to RDV to gain some insight into the fundamental physiological and biochemical changes that are induced by viral infection, in the hope of finding clues that might help to control the viral disease. An analysis, using microarrays, of gene expression in rice plants infected with Rice dwarf virus revealed significant decreases in levels of expression of genes that are involved in the formation of cell walls, reflecting the stunted growth of diseased plants. more...

(Submitter supplied) Strigolactones have been defined as a new group of phytohormones that regulate shoot branching. Tthe phenotypes of strigolacton-related rice (Oryza sativa) dwarf (d) mutants demonstrated that SLs inhibit mesocotyl elongation by controlling cell division. Moreover, the trans-zeatin, one of active cytokinins, content of mesocotyls was increased in the SL-deficient d10-1 and SL-insensitive d14-1 mutants. 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.
