Following in vitro infection with Agrobacterium rhizogenes wild strain (mannopine, 8196) and two A. tumefaciens transconjugant strains (C58C1 pArA4abc and C58C1 pArA4b) transformed (hairy) roots were induced in pumpkin (C. pepo L.) cotyledons. The presence of pRi T-DNA in pumpkin long-term hairy root cultures was determined by Southern hybridization. The influence of plant growth regulators on ...

In recent years exciting progress has been made in understanding how endogenous plant hormones control plant development. One of the fundamental questions in this area of research is the mechanism by which the presente of a plant hormone molecule (the signal) leads to a change in plant development (the transduction pathway). This Update will discuss progress in the genetic analysis of signal tr...

The cytokinin family of plant hormones is involved in diverse aspects of plant growth and development in vivo and in culture. Two groups have recently shown that a two-component histidine kinase functions as a cytokinin receptor specifically required for vascular development.

Background: Plant growth regulators (PGRs) have important roles in many processes such as germination, seedling growth, nutrition uptake, morphogenesis, ripening, etc. Objective: This study aimed to evaluate the effect of gibberellic acid, indole butyric acid, and methanol as plant growth regulators on morpho-physiological and phytochemical features in Thymus vulgaris L. Methods: The farm...

The present investigation was carried out with title “Effect of Plant Growth Regulators on growth, Yield and Fruit quality Brinjal (Solanum melongena L.)” at the Department Horticulture, Naini Agricultural Institute, Sam Higginbottom University Agriculture Technology Sciences, Prayagraj, Uttar Pradesh during Kharif-2021-22 a view to determine effect plant growth regulators application brinjal h...

Interplay between hormones is crucial for the coordination of plant development. Recent work has provided important new insights into the close relationship between brassinosteroid and auxin signalling pathways in plants.

The phytohormones auxin and cytokinin interact to regulate many plant growth and developmental processes. Elements involved in the biosynthesis, inactivation, transport, perception, and signaling of these hormones have been elucidated, revealing the variety of mechanisms by which signal output from these pathways can be regulated. Recent studies shed light on how these hormones interact with ea...

The present study was carried out to investigate micropropagation possibility and determine the optimal medium composition and plant growth regulators (PGRs) combinations under in vitro conditions. The cotyledon and epicotyl explants obtained from 1 month old in vitro grown seedlings were used in MS medium containing BA (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) and TDZ (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) e...
