Summary of "Arsenic-responsive high-affinity rice sulphate transporter, OsSultr1;1, provides abiotic stress tolerance under limiting sulphur condition."

In this study, the role of a rice high-affinity sulphate transporter, OsSultr1;1, in maintaining sulphur demand under arsenic (As) stress has been investigated. Saccharomyces cerevisiae mutant, YSD1, deficient in sulphur transport and Arabidopsis thaliana plants expressing OsSultr1;1, were used to analyze different parameters. Complementation of YSD1 using OsSultr1;1 showed tolerance towards heavy metals. Transgenic Arabidopsis lines expressing OsSultr1;1 developed a significant tolerance towards different abiotic stresses including heavy metals under sulphur limiting conditions. Transgenic lines showed 75-76% and 60-68% reduction in root length compared to 82% and 76% in wild type plants under arsenite [As(III); 10 μM] and arsenate [As(V); 100 μM] stress respectively. The analysis of superoxide radicals and hydrogen peroxide indicated reduced oxidative burst in transgenic as compared to wild type plants under As stress. Real-time PCR analysis showed differential expression of the genes associated with sulphur metabolism in the transgenic lines. A significant decrease (up to 50%) in malondialdehyde (MDA) levels and increased glutathione (GSH) content in transgenic lines demonstrated better detoxification mechanism compared to wild type plants under As stress. We conclude that over-expression of high-affinity sulphate transporters may provide tolerance towards different abiotic stresses under limiting sulphur environment.

Medical and Biotech [MESH] Definitions

A high-affinity, low capacity system y+ amino acid transporter with strong similarity to CATIONIC AMINO ACID TRANSPORTER 1. The two isoforms of the protein, CAT-2A and CAT-2B, exist due to alternative mRNA splicing. The transporter has specificity for the transport of ARGININE; LYSINE; and ORNITHINE.

A high-affinity, low capacity system y+ amino acid transporter found ubiquitously. It has specificity for the transport of ARGININE; LYSINE; and ORNITHINE. It may also act as an ecotropic leukemia retroviral receptor.

A high-affinity, ATP-binding, co-transporter for CARNITINE that is highly expressed in kidney, skeletal muscle, heart, and placental tissues. It transports one sodium ion with one carnitine molecule. It has a lower affinity for other organic cations and transports them independently of sodium. Mutations in the SLC22A5 gene are associated with systemic carnitine deficiency.

The anamorphic form of the fungus MAGNAPORTHE GRISEA and the most important pathogen of rice worldwide. It causes rice blast which prevents maturation of the rice grains.

A shiny gray element with atomic symbol As, atomic number 33, and atomic weight 75. It occurs throughout the universe, mostly in the form of metallic arsenides. Most forms are toxic. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), arsenic and certain arsenic compounds have been listed as known carcinogens. (From Merck Index, 11th ed)
