Penicillin-induced formation of ribonuclease in rice (Oryza sativa L.) endosperm and its inhibition by abscisic acid.

Numai utilizatorii înregistrați pot traduce articole

Penicillin stimulates the formation of ribonuclease in embryoless rice (Oryza sativa L.) endosperm and enhances gibberelin-induced response. Penicillin-induced RNase production is completely inhibited by abscisic acid.

Fluorogenic ribonuclease protection (FRIP) analysis of single nucleotide polymorphisms (SNPs) in Japanese Rice (Oryza sativa L.) DNA for cultivar discrimination.

Numai utilizatorii înregistrați pot traduce articole

A rapid and easy method to discriminate plant cultivars is indispensable to confirm food labeling. We established a fluorogenic ribonuclease protection (FRIP) assay to discriminate Japanese rice (Oryza sativa L.) cultivars based on single nucleotide polymorphisms (SNPs). The FRIP assay uses a

Inhibition of ribonuclease and protease activities in arsenic exposed rice seedlings: role of proline as enzyme protectant.

When seedlings of two rice (Oryza sativa L.) cvs. Malviya-36 and Pant-12 were raised under 25 and 50 microM As2O3 in the medium an increase in the level of RNA, proteins and proline accompanied with a decline in the level of free amino acid pool was observed under arsenic supplementation compared to

Fine mapping and candidate gene analysis of ptgms2-1, the photoperiod-thermo-sensitive genic male sterile gene in rice (Oryza sativa L.).

Numai utilizatorii înregistrați pot traduce articole

Photoperiod-thermo-sensitive genic male sterile (PTGMS) rice exhibits a number of desirable traits for hybrid rice production. The cloning genes responsible for PTGMS and those elucidating male sterility mechanisms and reversibility to fertility would be of great significance to provide a foundation

RNase T2 genes from rice and the evolution of secretory ribonucleases in plants.

Numai utilizatorii înregistrați pot traduce articole

The plant RNase T2 family is divided into two different subfamilies. S-RNases are involved in rejection of self-pollen during the establishment of self-incompatibility in three plant families. S-like RNases, on the other hand, are not involved in self-incompatibility, and although gene expression

Fine mapping of pss1, a pollen semi-sterile gene in rice (Oryza sativa L.).

Numai utilizatorii înregistrați pot traduce articole

During routine seed increase procedures in rice, semi-sterile plants are common; however, such semi-sterility mutants in rice varieties have been only rarely analyzed genetically. W207-2 is a semi-sterile selection from the japonica rice variety Nipponbare. In this report, we found the female gamete

Isolation and characterization of a putative transducer of endoplasmic reticulum stress in Oryza sativa.

Numai utilizatorii înregistrați pot traduce articole

Following endoplasmic reticulum (ER) stress that prevents correct folding or assembly of ER proteins, at least three responses occur to maintain cell homeostasis: induction of chaperones, attenuation of protein synthesis, and enhancement of lipid synthesis. Transducers that transmit ER stress to the

Multiple RNA binding protein complexes interact with the rice prolamine RNA cis-localization zipcode sequences.

Numai utilizatorii înregistrați pot traduce articole

RNAs for the storage proteins, glutelins and prolamines, contain zipcode sequences, which target them to specific subdomains of the cortical endoplasmic reticulum in developing rice (Oryza sativa) seeds. Fifteen RNA binding proteins (RBPs) specifically bind to the prolamine zipcode sequences and are

RNA sequencing-mediated transcriptome analysis of rice plants in endoplasmic reticulum stress conditions.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The endoplasmic reticulum (ER) stress response is widely known to function in eukaryotes to maintain the homeostasis of the ER when unfolded or misfolded proteins are overloaded in the ER. To understand the molecular mechanisms of the ER stress response in rice (Oryza sativa L.), we

Biochemical factors affecting protein accumulation in the rice grain.

Numai utilizatorii înregistrați pot traduce articole

Rice grains (Oryza sativa L.) from three varieties and three pairs of lines with different protein content were collected at 4-day intervals from 4 to 32 days after flowering. The samples were analyzed for protein, free amino nitrogen, ribonucleic acid, protease activity, and ribonuclease activity.

An arginyl-transfer ribonucleic Acid protein transferase from cereal embryos.

Numai utilizatorii înregistrați pot traduce articole

Embryos from rice (Oryza sativa L. var. Bluebonnet) and wheat (Triticum aestivum L.) contain an aminoacyl-tRNA protein transferase which transfers arginine from arginyl-tRNA to the N terminus of a protein acceptor. The activity was measured in vitro in a reaction mixture containing embryo

Characterization of two rice DNA methyltransferase genes and RNAi-mediated reactivation of a silenced transgene in rice callus.

Numai utilizatorii înregistrați pot traduce articole

Two genomic clones ( OsMET1-1, AF 462029 and OsMET1-2, TPA BK001405), each encoding a cytosine-5 DNA methyltransferase (MTase), were isolated from rice ( Oryza sativa L.) BAC libraries. OsMET1-1 has an open reading frame of 4,566 nucleotides with 12 exons and 11 introns while OsMET1-2 has an open

Genome-wide identification and characterization of tRNA-derived RNA fragments in land plants.

UNASSIGNED The manuscript by Alves et al. entitled "Genome-wide identification and characterization of tRNA-derived RNA fragments in land plants" describes the identification and characterization of tRNAderived sRNA fragments in plants. By combining bioinformatic analysis and genetic and molecular
