T he central roles of potassium channels in regulating membrane potential and controlling action potential repolarization are well documented (1). In plants an additional important function of potassium channels in mediating long-term potassium transport during cell movements, turgor changes, and tropisms has been proposed. Two guard cells surround each stomatal pore in leaves and control the o...

optimal level of regulation and regulatory reform seem to be an undisputed objective . however, in the context of financial regulation there are differences and disagreements over the optimal level of disclosure of information and capital adequacy standards. in this paper, instead of offering a substantive solution , we argue for a competitive process through which the optimal level of disclosu...

Stomatal closure is affected by various stimuli such as light, atmospheric carbon dioxide concentration, humidity and phytohormones. Our research focuses on phytohormones, specifically: abscisic acid (ABA), ethylene (ET) and methyl jasmonate (MeJA) that are responsible for the regulation of several plant processes, especially in guard cell signalling. While several studies show that these three...

Rice production has been significantly hindered by frequent drought events in recent times, directly impacting food security and agricultural sustainability. In the current study, a set of 100 diverse rice accessions from 3K RG panel were evaluated for Epidermal patterning factor 2 (OsEPF2) loci which governs stomatal density on matured leaves preventing excessive development. This plays an imp...

Squalene epoxidase enzymes catalyse the conversion of squalene into 2,3-oxidosqualene, the precursor of cyclic triterpenoids. Here we report that the Arabidopsis drought hypersensitive/squalene epoxidase 1-5 (dry2/sqe1-5) mutant, identified by its extreme hypersensitivity to drought stress, has altered stomatal responses and root defects because of a point mutation in the SQUALENE EPOXIDASE 1 (...
