A biotin-labeled in situ hybridization technique was used in order to physically map RFLP markers to the chromosomes of rice (Oryza sativa L.). Fourteen RFLP markers, associated with the ends of the linkage groups on rice chromosomes 7, 8, 11, 12, were physically mapped onto specific regions of the
Small noncoding RNAs are essential for gene expression at transcriptional and posttranscriptional levels. Northern blot is the most used method for small RNA detection in tissues. Here we present an improved protocol for the Northern blot-based small RNA detection from plant tissues by using
We describe a simple, rapid method for protein complex purification in planta. Using a biotin peptide as an affinity tag with TATA-box binding protein (TBP), 86 unique proteins present in the purified complex were identified by tandem mass spectrometry. We identified proteins known to be associated
This study was designed to use biotin labelling in situ hybridization to physically map the 5S rDNA genes to a chromosome arm location in rice. Chromosome preparations were made using an improved protoplast technique, which resulted in more mitotic cells with less overlying cytoplasmic and cellular
Rice bran is an underutilized agricultural by-product with economic importance. The unique phytochemicals and fatty acid compositions of bran have been targeted for nutraceutical development. The endogenous lipases and hydrolases are responsible for the rapid deterioration of rice bran. Hence, we
Rice (Oryza sativa var. Nipponbare) was transformed with an artificial avidin gene. The features of this construct are as follows: (1) a signal peptide sequence derived from barley alpha amylase was added at the N-terminal region, (2) codon usage of the gene was optimized for rice, and (3) the gene
BACKGROUND
Small non-coding RNAs are essential regulators of gene expression at the transcriptional and posttranscriptional levels. High-throughput sequencing has revealed thousands of predicted small RNAs; however, only a few of these have been well characterized. Northern blotting is the most
Nitric oxide (NO) is a key redox-active, small molecule involved in various aspects of plant growth and development. Here, we report the identification of an NO accumulation mutant, nitric oxide excess1 (noe1), in rice (Oryza sativa), the isolation of the corresponding gene, and the analysis of its
MicroRNAs (miRNAs) play important regulatory roles in animals and plants by targeting mRNAs for cleavage or translational repression. They have diverse expression patterns and might regulate various developmental and physiological processes. Profiling miRNA expression is very helpful for studying
