(Submitter supplied) We aimed to reveal transitions of gene expression profile in developing female gametophytes of rice in this study. The developmental process of rice female gametophyte, from megaspore mother cell at pre-meiotic stage to mature embryo sac, was separated into six stages. Developing ovules at each stage were separated from surrounding sporophyte tissues and collected using LMD. RNA samples extracted from them were subjected to microarray analysis. more...

(Submitter supplied) Gene expression throughout the reproductive process in rice (Oryza sativa) beginning with primordia development through pollination/fertilization to zygote formation was analyzed. We analyzed 25 stages/organs of rice reproductive development including early microsporogenesis stages with 57,381 probe sets, and identified around 26,000 expressed probe sets in each stage. Fine dissection of 25 reproductive stages/organs combined with detailed microarray profiling revealed dramatic, coordinated and finely tuned changes in gene expression. more...

(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) To investigate the responses of resistance gene Pi54 at transcriptome level in blast resistant transgenic rice line TP-Pi54 during infection by Magnaporthe oryzae, we studied the co-expression analysis using microarray along with susceptible non-transgenic line Taipei 309 (TP). Suitable controls for both lines were used. The comparative analysis of differentially expressed genes was conducted.

(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) 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...

Our aims were to: 1) identify genes expressed in a tissue-specific and temporal-specific manner; 2) define clusters of genes showing similar patterns of spatial and temporal expression; and 3) identify stage-specific or transition-specific candidate genes for further functional genomic analyses.We analyzed gene expression during S. more...
