proline/oryza sativa

The regulation of proline accumulation in seedlings of rice (Oryza sativa L. cv. Badami) was investigated. The increasing concentration of NaCl from 0.5 to 2.5% progressively increased the proline content in rice. Proline accumulation caused by NaCl was related to protein proteolysis, an increase in

The present study investigates the roles of exogenous proline (Pro, 5 mM) and glycine betaine (GB, 5 mM) in improving salt stress tolerance in salt sensitive (BRRI dhan49) and salt tolerant (BRRI dhan54) rice (Oryza sativa L.) varieties. Salt stresses (150 and 300 mM NaCl for 48 h) significantly

Proline is one of the precursors of the biosynthesis of 2-acetyl-1-pyrroline (2-AP) which is the key and characteristic volatile component of fragrant rice aroma. In order to study the effects of exogenous proline on 2-AP biosynthesis and other grain quality attributes in fragrant rice, two indica

Application of N-2-(chloro-4-pyridyl)-N-phenyl urea (CPPU) to salt susceptible cultivar of indica rice (cv. PTT1) effected on free proline and soluble sugar accumulation and regulated the physio-morphological responses when subjected to salt stress condition was firstly demonstrated in this study.

Gene duplication has been recognized as a major route to supply raw sequences for genome novelty in evolution, but the mechanism underlying the retention of duplicate genes is not fully understood yet. Divergence in spatial expression patterns was investigated here and in response to stimuli of the

Proline-rich proteins (PRPs) play multiple physiological and biochemical roles in plant growth and stress response. In this study, we reported that the knockout of OsPRP1 induced cold sensitivity in rice. Mutant plants were generated by CRISPR/Cas9 technology to investigate the role of

Conditions were optimised for efficient callus induction from seeds of four local indica rice cultivars, GR-3, GR-102, Jaya and Te-Tep. Addition of 2,4-D to MS medium at 2.5 mg/l resulted in 100% callus induction. N6 medium was superior to MS medium for callus growth, formation of embryogenic callus

Proline accumulation is involved in plant osmotic stress tolerance. Given that DNA methylation is related to almost all metabolic processes through regulation of gene expression, we suspected that this epigenetic modification and proline biosynthesis are probably related. To test this, we

The Asian rice gall midge (ARGM), Orseolia oryzae is an important insect pest causing an annual yield loss of about US$ 80 million in India. Till now 11 R genes and seven biotypes of the pest have been characterized and reported. The indica rice variety Aganni, a landrace from the state of Kerala,

NaCl and PEG stresses have negative impacts on seed germination and early seedling establishment in Oryza sativa. The present study was designed to ascertain the influence of different priming techniques (Hydro priming-HyP, Halo priming-HP, UV-B priming-UP) in enhancing oxidative and

Suspension cultures which maintained embryogenic potency for more than 18 months were established from excised immature embryos of rice (Oryza sativa L. cv. Konansou). The cultures were subcultured every three days in N6 medium supplemented with proline (10 mM), casein hydrolysate (300 mg/l),

The response of plant cells to salt stress was studied on embryo derived calli of rice (Oryza sativa L.) in order to identify cellular phenotypes associated with the stress. The feasability of selecting salt tolerant callus and its subsequent regeneration to plants was also studied. Callus was grown

An efficient in vitro plant regeneration system was established for elite, recalcitrant Malaysian indica rice, Oryza sativa L. CV. MR 219 using mature seeds as explant on Murashige and Skoog and Chu N6 media containing 2,4-dichlorophenoxy acetic acid and kinetin either alone or in different

1-Aminocyclopropane-1-carboxylate (ACC) deaminase is a plant growth promoting (PGP) trait found in beneficial bacteria including streptomycetes and responsible for stress modulation. The ACC deaminase gene, acdS, of S. venezuelae ATCC 10712 was cloned into an expression plasmid, pIJ86, to generate
