sorbitol/oryza sativa

The sorbitol-6-phosphate dehydrogenase (S6PDH) is a key enzyme for sorbitol synthesis and plays an important role in the alleviation of salinity stress in plants. Despite the huge significance, the structure and the mode of action of this enzyme are still not known. In the present study, sequence

This experiment assessed the effect of partial physical desiccation on plant regeneration efficiency in scutellum-derived embryogenic calluses of rice (Oryza sativa L.) variety Super basmati. A number of callusing cultures were developed, and efficient callus induction was observed on MS (Murashige

When compared with Photosystem I (PSI) in wild-type (WT) rice plants, PSI in PsbS-knockout (KO) plants that lack the energy-dependent component of nonphotochemical quenching (NPQ) was less sensitive to photoinhibition. Therefore, we investigated the relationship between NPQ and cyclic electron flow

Rice embryogenic suspension cells were successfully cryopreserved by a pregrowth-desiccation procedure. Cells were precultured in liquid AA medium containing 0.175 mol/L sucrose for 3 d and then in liquid AA medium containing 0.4 mol/L sorbitol for 1 d. After air-drying for about 20 h to a water

An in situ regeneration system for rice calli comprised of a callus growth stage and two regeneration stages was developed. After the first stage of regeneration, the medium is changed and the calli are immobilized in polyurethane foam supports, in each of which 3-5 regenerated plantlets develop

Rice cells were precultured for 10 d in medium containing 60 g/L sucrose and subsequently for 1 d in medium supplemented with 0. 4 M sorbitol. After loading with 25%PVS2 at 22°C for 10 min and dehydration in 100%PVS2 at 0°C for 7. 5 min,they were plunged into liquid nitrogen directly. Survival was

Root and embryo derived callus tissues of rice grown on sucrose alone as carbon source lost their ability to organise shoots by 75 and 100 days in culture respectively. Along with 2% sucrose, either 3% sorbitol or 3% mannitol was found to be necessary in the growth medium for the callus to

Rice (Oryza sativa L.) is one of the leading crops and the basis of most diets in Ecuador and other countries. Diseases such as bacterial panicle blight (BPB), also known as seedling rot or grain rot, have the potential to threaten rice production worldwide. Burkholderia glumae, a causal agent of

Mineral balance and salt stress are major factors affecting plant growth and yield. Here, we characterized the effects of rice (Oryza sativa L.) reduced culm number1 (rcn1), encoding a G subfamily ABC transporter (OsABCG5) involved in accumulation of essential and nonessential minerals, the Na/K

Transgenic suspension cells of Oryza sativa L. cv. Dongjin utilized as a host for producing recombinant human cytotoxic T-lymphocyte antigen 4-immunoglobulin (hCTLA4Ig) were preserved in liquid nitrogen (-196 degrees C) after slow prefreezing in a deep freezer (-70 degrees C). The development of an

In September 2009, leaf blights were observed on rice (Oryza sativa L., variety Dongjin 1 and Hopyeong) in paddy fields located in Gwangyang and Naju, Jeonnam Province, Korea. Lesions appeared first as water-soaked stripes or light brown-to-slightly reddish spots on the upper blades of the leaves,
