Plant Growth Regulators II: Cytokinins, their Analogues and Antagonists
Hormones in plants differ from most of those in animals by having pleiotropic effects; that is, they are involved in the control of a wide range of developmental processes. At the same time the effect of a hormone on any developmental process depends on the species. For example, ethylene inhibits growth in dicotyledons and most monocotyledons but is promotory in deepwater rice and other hydroph...
متن کاملEffects of Seawater Salinity and Temperature on Growth and Pigment Contents in Hypnea cervicornis J. Agardh (Gigartinales, Rhodophyta)
This study simulated outdoor environmental living conditions and observed the growth rates and changes of several photosynthetic pigments (Chl a, Car, PE, and PC) in Hypnea cervicornis J. Agardh (Gigartinales, Rhodophyta) by setting up different ranges of salinity (25, 30, 35, 40, 45, and 50) and temperature (15, 20, 25, and 30°C). At conditions of culture, the results are as follows. (1) Chang...
متن کاملAntibacterial and antioxidant activities of the red algae Hypnea charoides from coasts of Chabahar
Background and objectives: Marine macro algae are one of the most economically important resources of the oceans which contain important biologically active secondary metabolites. So they can be widely used in various applications. Due to the limited research work on the bioactive metabolites from Iranian algae, the red seaweed, Hypnea charoides, collected from interti...
متن کاملCytokinins are central regulators of cambial activity.
The roots and stems of dicotyledonous plants thicken by the cell proliferation in the cambium. Cambial proliferation changes in response to environmental factors; however, the molecular mechanisms that regulate cambial activity are largely unknown. The quadruple Arabidopsis thaliana mutant atipt1;3;5;7, in which 4 genes encoding cytokinin biosynthetic isopentenyltransferases are disrupted by T-...
