Hemibiotrophic Modulates the Expression of SWEET Genes in Potato ( L.).

Sugar Efflux transporters (SWEET) are involved in diverse biological processes of plants. Pathogens have exploited them for nutritional gain and subsequently promote disease progression. Recent studies have implied the involvement of potato genes in the most devastating late blight disease caused by .

Root system architecture for abiotic stress tolerance in potato: Lessons from plants.

The root is an important plant organ, which uptakes nutrients and water from the soil, and provides anchorage for the plant. Abiotic stresses like heat, drought, nutrients, salinity, and cold are the major problems of potato cultivation. Substantial research advances have been achieved in cereals and model plants on root system architecture (RSA), and so root ideotype (e.

Germplasm, Breeding, and Genomics in Potato Improvement of Biotic and Abiotic Stresses Tolerance.

Potato is one of the most important food crops in the world. Late blight, viruses, soil and tuber-borne diseases, insect-pests mainly aphids, whiteflies, and potato tuber moths are the major biotic stresses affecting potato production. Potato is an irrigated and highly fertilizer-responsive crop, and therefore, heat, drought, and nutrient stresses are the key abiotic stresses.

Seedling stage low temperature response in tolerant and susceptible rice genotypes suggests role of relative water content and members of OsSNAC gene family.

Low temperature (LT) severely affects rice growth and grain yield. Recently, we reported contrasting genotypes including ARR 09 and Takyer for seedling stage long duration low temperature response. Here we show that susceptible rice genotypes show an increase in lipid peroxide levels and decrease in relative water content (RWC) to a higher extent in comparison to tolerant genotypes in response to 3 h LT.

Allele mining across DREB1A and DREB1B in diverse rice genotypes suggest a highly conserved pathway inducible by low temperature.

Low temperature stress is one of the major limiting factors affecting rice productivity in higher altitudes. DREB1A and DREB1B, are two transcription factors that have been reported to play key regulatory role in low temperature tolerance. In order to understand whether natural genetic variation in these two loci leads to cold tolerance or susceptibility, OsDREB1A and OsDREB1B were targeted across several rice genotypes showing differential response to low temperature.
