Chemical root to shoot signaling under drought.
Chemical signals are important for plant adaptation to water stress. As soils become dry, root-sourced signals are transported via the xylem to leaves and result in reduced water loss and decreased leaf growth. The presence of chemical signals in xylem sap is accepted, but the identity of these signals is controversial. Abscisic acid (ABA), pH, cytokinins, a precursor of ethylene, malate and ot...
متن کاملA Simple and Efficient Direct Shoot Organogenesis Method Using Leafy Petiole Explants in Gerbera jamesonii ‘Royal Soft Pink’
The gerbera market would benefit from an efficient and simple protocol for high rate regeneration for propagation and genetic engineering. With these objectives, this investigation was done on shoot regeneration via direct organogenesis from leafy petiole explants of Gerbera jamesonii ‘Royal Soft Pink’. Murashige and Skoog (1962) (MS) medium was supplemented with 0.1 mg L-1 indole-3-acetic acid...
متن کاملCarbon Allocation to Root and Shoot Systems of Woody Plants
Carbon allocation to roots is of widespread and increasing interest due to a growing appreciation of the importance of root processes to whole-plant physiology and plant productivity. Carbon (C) allocation commonly refers to the distribution of C among plant organs (e.g., leaves, stems, roots); however, the term also applies to functional categories within organs such as defense, injury, repair...
متن کاملSimple and Efficient Method for the Preparation of 5-Bromoisatins
Isatin, N-methyl isatin and N-benzylisatin were smoothly monobrominated in the 5-position by treatment with pyridinium bromochromate (PBC) in acetic acid medium. In the similar conditions indigo underwent bromination and oxidation to give 5-bromoisatin in high yield.
متن کاملDehydration-stress-regulated transgene expression in stably transformed rice plants
To confer abscisic acid (ABA) and/or stress-inducible gene expression, an ABA-response complex (ABRC1) from the barley (Hordeum vulgare L.) HVA22 gene was fused to four different lengths of the 5' region from the rice (Oryza sativa L.) Act1 gene. Transient assay of beta-glucuronidase (GUS) activity in barley aleurone cells shows that, coupled with ABRC1, the shortest minimal promoter (Act1-100P...
