Background: Effects of cadmium (Cd) metal on growth, photosynthetic pigments, level of osmolytes and elements, and antioxidant potential of Brassica juncea seedlings were evaluated. Materials and Methods: Seeds were exposed to different concentrations of metal, i.e., 0, 0.2, 0.4, and 0.6 mM Cd. To investigate the metal influence on biochemical and physiological factors, observations were made o...

Chlorophylis cl and c2 have been separted from total pigment extracts of the alg Pavlovagyras Butcher using a reversed-phae high-performance liquid chromatography system. Pigments were separated on a 5 micrometer Cl, column (25 centimeters x 4.6 millimeters) using a gadient ofmethanol-acetonitrile-water. Other photosynthetic pigments were also well resolved by the system used. The separation sy...

Effect of cobalt (Co) stress on morphological parameters and pigments of Arachis hypogaea L. were studied. Growth parameters such as, root and shoot length, number of nodules, total leaf area and root and shoot dry weights; photosynthetic pigments viz., chlorophyll ‘a’, chlorophyll ‘b’, total chlorophyll and carotenoid contents were analysed. Growth parameters and pigments have beneficial value...

Water and nitrogen are two of the most important factors for plant growth and development. However, little is known about effects of N on water translocation between connected bamboo ramets. We performed experiment connected Indocalamus decorus ramets in adjacent pots with different soil water contents and three N levels. We determined antioxidase activities, concentration of osmotic adjustment...

Fucoxanthin, diadinoxanthin and diatoxanthin are carotenoids found in brown algae and most other heterokonts. These pigments are involved in photosynthetic and photoprotective reactions, and they have many potential health benefits. They can be extracted from diatom Phaeodactylum tricornutum by sonication, extraction with chloroform : methanol and preparative thin layer chromatography. We asses...

Acquisition of new photosynthetic pigments has been a crucial process for the evolution of photosynthesis and photosynthetic organisms. In this process, pigment-binding proteins must evolve to fit new pigments. Prochlorococcus is a unique photosynthetic organism that uses divinyl chlorophyll (DVChl) instead of monovinyl chlorophyll. However, cyanobacterial mutants that accumulate DVChl immediat...

Maximizing light capture by light-harvesting pigment optimization represents an attractive but challenging strategy to improve photosynthetic efficiency. Here, we report that loss of a previously uncharacterized gene, HIGH PHOTOSYNTHETIC EFFICIENCY1 (HPE1), optimizes light-harvesting pigments, leading to improved photosynthetic efficiency and biomass production. Arabidopsis (Arabidopsis thalian...

This study aimed to evaluate the variation in the levels of proline, oxidative metabolism and photosynthetic pigments in plants of Pitcairnia encholirioides grown in vitro under different conditions and after acclimatization. The analyses were performed after 150 days of in vitro cultivation in MS media supplemented with 10 µM GA3 or 0.2 µM NAA, sucrose at 15 or 30 g L-1, in test tubes which al...
