The effects of gibberellic acid on Allium cepa root tip meristematic cells
Biologia Plantarum, 2019 Gibberellic acid (GA) is a natural plant growth regulator (PGR) which stimulates germination, vegetative growth, flowering, and fruit formation. However, when high concentrations of GA are used, it inhibits plant growth and development and causes ...

Ecotoxicology and Environmental Safety, 2014 The present study was aimed at evaluating phytotoxicity of various concentrations of lead nitrate (0, 100, 200, 400, 600, 800 and 1000mgL(-1)) in Sesbania grandiflora. The seedling growth was significantly affected (46%) at 1000mgL(-1) lead (Pb) treatment.

South African Journal of Botany, 2017 Abstract Excess of fluoride (F) in irrigation water is a serious threat inducing variety of deleterious impacts in plants via over-production of active oxygen species (AOS), modifying antioxidant enzymes and nucleic acid. Present study was aimed to monitor protective functions of glycinebetaine (GB) against F-toxicity in Cajanus cajan L. GB is an

Protecting exons from deleterious R-loops: a potential advantage of having introns
Biology Direct, 2007 Background Accumulating evidence indicates that the nascent RNA can invade and pair with one strand of DNA, forming an R-loop structure that threatens the stability of the genome. In addition, the cost and benefit of introns are still in debate.

QUALITATIVE ASSESSMENT OF CADMIUM STRESS USING GENOME TEMPLATE STABILITY IN Hordeum vulgare
Egyptian Journal of Genetics and Cytology, 2010 Cadmium, a non essential heavy metal, does not play any metabolic role and is considered as toxic element even at very low concentration. It is mainly generated through anthropogenic activities, such as mining deposits, aerial fallout from smelters and from industrial, agricultural, energy and municipal sources (McGrath et al., 2001; McBride, 2003 ...
