The light harvesting like protein 3 (LIL 3) from higher plants, has been linked to functions in chlorophyll and tocopherol biosynthesis, photo-protection and chlorophyll transfer. However, the binding of chlorophyll to LIL3 is unclear. We present a reconstitution protocol for chlorophyll binding to LIL3 in DDM micelles. It is shown in the absence of lipids and carotenoids that reconstitution of...
The partition of phylloquinone (vitamin K J, of chlorophylls a and b and of the two main carotenoids, /?-carotene and lutein, in subthylakoid particles (digitonin treatment) and chlorophyll protein complexes (sodium dodecylsulfate polyamide-gel electrophoresis) isolated from tobacco chloroplasts (Nicotiana tabacum L.) is described. 1. The “light particle” fractions (S 90000, S 150000) of digito...
Iron chlorosis is an important disorder of plane trees (Plantanus orintalis L.) in green space of Isfahan city. Before using reclamation methods for correcting Fe chlorosis, it is necessary to find a suitable index for evaluating plant Fe status. Therefore, activity of glutathione peroxidase (GP) enzyme and concentration of carotenoids and chlorophyll a and b pigments, as physiological indices ...
Plants are faced with various environmental stresses during their growing period. Each of these stresses have different effects on growth, metabolism and yield according to the sensitivity level and stage of the plant growth. One way of reducing the negative effects of the stresses is to use humic substances. The present study was carried out to evaluate the effects of humic acid and drought st...
Introduction Leaf senescence involves degradation of proteins, The activities of chlorophyllase, contents of pigments chlorophylls, nucleic acids, membranes, and subsequent including chlorophyll a and b, chlorophyllide a and b, transport of some of the degradation products to other and phaeophorbide a during leaf senescence under parts of the plant (Buchanan-Wollaston, 1997; Noodén, low oxygen ...
Using bacteria for producing plant nutrients, applying proper methods of soil fertility, and nutrition of plants, other than preserving environment and human health, eliminates unnecessary and wasteful use of chemical fertilizers. Thus, in order to achieve this aim, a greenhouse experiment was carried out, based on completely randomized design with three replications, in Damavand city, during 2...
In order to investigating the effects of composts containing the natural zeolite- and the Mg-modified zeolites- (CNZ and CMZ, respectively) on some morphological and physiological traits, greenhouse experiments as a completely randomized design with eight treatments and three replications were performed. The results showed that the using compost especially containing Mg-modified zeolites increa...
In order to investigate the effects of drought stress and silica spraying on some physiological characteristics of canola, an experiment was conducted in the research farm of Behbahan University in 2016-2017. In the present study, the effect of concentrations of 0 (S0) and 30 (S1) mM potassium silicate under normal irrigation conditions (irrigation after %25 of available water discharges) and d...
Mycorrhizal fungi symbiosis with plants root through effective uptake of water and nutrients can be reduced the negative effects of salinity. To evaluate the effect of mycorrhizal fungi on some morpho-physiological traits and yield of Summer savory a greenhouse factorial experiment was conducted based on randomized complete block design with three replications at the Laboratory of Medicinal Pla...
