INTRODUCTION Jasmonoids have been found to play important roles in plant growth regulation.1 Recent development of industrial production of ()-methyl jasmonate (MJA, 1) from Nippon Zeon Co., Ltd. made it possible to use MJA as a practical plant growth regulator.2 we have been studying new jasmonoid analogs to develop more active compounds.3 we took notice of the hypothesis that the metabolic in...
Black cumin (Nigella sativa) is an annual flowering plant in the family Ranunculaceae that beside medicinal value was used as food and cosmetics products. Salicylic acid is a growth regulator with phenolic nature has main role in regulation of many physiological processes and resistance to environmental stress. In order to study effect of salt stress and salicylic acid on some growth parameters...
P-37: Effect of Gibberellic Acid on Sperm DNA Double Strand Integrity, Nuclear Maturity and Motility
Background: Plant growth regulators gave entry into animals and human cells through diet. Gibberellic acid (GA3) is an extensively prevalent plant growth regulator due to its use in agriculture. Therefore current study was designed to investigate the effect of GA3 compound on sperm DNA integrity, nuclear maturity and motility. Materials and Methods: To follow-up current study 12 mature male s r...
The plant hormone ethylene is an important signal in plant growth responses to environmental cues. In vegetative growth, ethylene is generally considered as a regulator of cell expansion, but a role in the control of meristem growth has also been suggested based on pharmacological experiments and ethylene-overproducing mutants. In this study, we used transgenic ethylene-insensitive and ethylene...
The gaseous plant hormone ethylene regulates a multitude of growth and developmental processes. How the numerous growth control pathways are coordinated by the ethylene transcriptional response remains elusive. We characterized the dynamic ethylene transcriptional response by identifying targets of the master regulator of the ethylene signaling pathway, ETHYLENE INSENSITIVE3 (EIN3), using chrom...
Plant organ size and thus plant size is determined by both cell proliferation and cell expansion. The bHLH transcription factor SPATULA (SPT) was originally identified as a regulator of carpel patterning. It has subsequently been found to control growth of the organs of the shoot. It does this at least in part by controlling the size of meristematic regions of organs in parallel to gibberellic ...
Water deficit is one of the most important environmental stresses limiting plant growth and crop yield. While the identification of many key factors involved in the plant water deficit response has greatly increased our knowledge about the regulation system, the mechanisms underlying dehydration tolerance in plants are still not well understood. In our current study, we investigated the roles o...
Forage sorghum presents tall plants, what makes mechanicalseed harvesting a difficult task. Plant hormones can reduce plant height andfacilitate the harvesting. Thus, objective of this study was to evaluatethe effect growth regulator trinexapac-ethyl on and seedyield in forage sorghum. This research carried out at Embrapa Maizeand Sorghum, two seasons (2017 2018), randomized completeblock desig...
Plant growth and development are regulated by numerous internal and external factors. Among these, gibberellin (GA) (an endogenous plant growth regulator) and phytochrome (a photoreceptor) often influence the same processes. For example, in plants grown in the light Arabidopsis thaliana hypocotyl elongation is reduced by GA deficiency and increased by phytochrome deficiency. Here we describe ex...
