Identification of 20 microRNAs from Oryza sativa.
MicroRNAs (miRNAs) are present in both plant and animal kingdoms and represents a growing family of non-coding RNAs. These tiny RNAs act as small guides and direct negative regulations usually in the process of development through sequence complementarity to target mRNAs. Although a large number of miRNAs have been identified from various animals, so far plant miRNA studies have focused mainly ...
متن کاملIdentification of stress-responsive genes in an indica rice (Oryza sativa L.) using ESTs generated from drought-stressed seedlings.
The impacts of drought on plant growth and development limit cereal crop production worldwide. Rice (Oryza sativa) productivity and production is severely affected due to recurrent droughts in almost all agroecological zones. With the advent of molecular and genomic technologies, emphasis is now placed on understanding the mechanisms of genetic control of the drought-stress response. In order t...
متن کاملComputational Analysis of Abiotic Stress Inducible Genes and Proteins from Rice (oryza Sativa L.)
In this communication, various in silico based prediction tools were employed to localize various stress-inducible genes [dehydrin (viz., RAB16A), polyamine-biosynthesis enzyme (viz., SAMDC), transcription factors (OSBZ8, NAC1, DREBP2, CRT/DRE-BP, WRKY24/51/71), ion channels and membrane transporters (HKT1, NHX1, SOS3) and protein kinases (SAPK5/7)] on rice chromosomes and establish their exon-...
متن کاملIdentification and Expression Analysis of microRNAs at the Grain Filling Stage in Rice(Oryza sativa L.)via Deep Sequencing
MicroRNAs (miRNAs) have been shown to play crucial roles in the regulation of plant development. In this study, high-throughput RNA-sequencing technology was used to identify novel miRNAs, and to reveal miRNAs expression patterns at different developmental stages during rice (Oryza sativa L.) grain filling. A total of 434 known miRNAs (380, 402, 390 and 392 at 5, 7, 12 and 17 days after fertili...
متن کاملCloning and characterization of a water deficit stress responsive transcription factor gene from Oryza sativa L.
Understanding the biochemical and molecular basis of drought mechanism in rice is important as drought is one of the major causes affecting rice crop adversely. A 1017 bp gene sequence encoding AP2/ERF family TF was isolated from Oryza sativa sp. Indica cv N22 encoding a protein of 338 amino acid residues, with a molecular weight of 36.58 kDa, and no intron in the ORF. The gene was named as AP2...
