Calcium (Ca²⁺) regulates several signalling pathways involved in growth, development and stress tolerance. Cellular Ca²⁺ homeostasis is achieved by the combined action of channels, pumps antiporters, but direct evidence for a role Ca²⁺ATPase tolerance lacking. Here we report characterization ATPase gene (OsACA6) from Oryza sativa, elucidate its functions OsACA6 transcript levels are enhanced response to salt, drought, abscisic acid heat. In vivo localization identified plasma membranes as an...
The ability of plants to maintain photosynthesis in a dynamically changing environment is central importance for their growth. As the photosynthetic machinery sensitive and early target adverse environmental conditions as those typically found field, efficiency not always optimal. Cyanobacteria, algae, mosses, liverworts gymnosperms produce flavodiiron proteins (Flvs), class electron sinks represented angiosperms; these act mitigate photoinhibition photosystem I under high or fluctuating...
The DEAD-box RNA helicase family comprise enzymes that participate in every aspect of metabolism, associated with a diverse range cellular functions including response to abiotic stress. In the present study, we report on identification new ATP-binding protein (OsABP) from rice which is upregulated e multiple stress treatments NaCl, dehydration, ABA, blue and red light. It possesses an ORF 2772 nt, encoding 923 aa, contains DEAD C-terminal domains, along nine conserved motifs specific...
A direct somatic embryogenesis protocol was developed for four cultivars of Nicotiana species, by using leaf disc as an explant. Direct BAP and IAA has not been investigated so far. This method does require formation callus tissues which leads to somaclonal variations. The frequency strongly influenced the plant growth hormones. embryos developing directly from explant tissue were noticed after 6 d culture. Somatic a high (87–96%) observed in cultures all genotypes (Nicotiana tabacum, N....
An efficient method for in vitro micro propagation and genetic transformation of plants are crucial both basic applied research. Maize is one the most important cereal crops around world. Regeneration from immature embryo hampered due to its unavailability round year. On contrary mature especially tropical maize recalcitrant toward tissue culture. Here we report a highly regeneration (90%) system by using 2 different approaches i.e., embryogenic organogenic callus cultures. Seeds were...
Ocimum leaves are highly enriched in antioxidant components. Thus, its leaf extract, if applied plants, is believed to efficiently scavenge ROS, thereby preventing oxidative damage under drought stress. the present study was performed kharif 2013 and rabi 2014 season evaluate effect of aqueous extract sanctum against stress 2 rice genotype glass house conditions. Here we show that various morpho- physiological (chlorophyll fluorescence, rolling score, tip burn, number senesced total dry...
With the notable exception of angiosperms, all phototrophs contain different sets flavodiiron proteins that help to relieve excess excitation energy on photosynthetic electron transport chain during adverse environmental conditions, presumably by reducing oxygen directly water. Among them, Flv2-Flv4 dimer is only found in β-cyanobacteria and induced high light, supporting a role stress protection. The possibility similar protective function plants was assayed expressing Synechocystis...
Abstract Malformation of mango inflorescences (MMI) disease causes severe economic losses worldwide. Present research investigates the underlying MMI. Results revealed significantly higher levels cyanide, a by-product ethylene biosynthesis, in malformed (MI) cultivars. There was significant rise ACS transcripts, enzyme activity and cyanide MI as compared to healthy (HI). Significant differences methionine, phosphate, S-adenosyl-L-methionine, S-adenosyl-L-homocysteine, ascorbate glutathione,...
Chloroplasts, the sites of photosynthesis in higher plants, have evolved several means to tolerate short episodes drought stress through biosynthesis diverse metabolites essential for plant function, but these become ineffective when duration is prolonged. Cyanobacteria are closest bacterial homologs plastids with two photosystems perform and evolve oxygen as a byproduct. The presence Flv genes encoding flavodiiron proteins has been shown enhance tolerance cyanobacteria. In an attempt...
Mango malformation is the most important and threatening disease of recent times, primarily because persistent lacuna in complete understanding its nature. Diverse Fusarium spp, including F. mangiferae, were found to be associated with disease. Here, mangiferae from mango cv Dashehri was morphologically characterized. Typically, oval-shaped microconidia without septum crescent-shaped macroconidia 3-septate more often observed, whereas not a single chlamydospore detected. The length width...

Abstract The ability of plants to maintain photosynthesis in a dynamically changing environment is central importance for their growth. As photosynthetic machinery typically cannot adapt rapidly fluctuations the intensity radiation, level efficiency not always optimal. Cyanobacteria, algae, non-vascular (mosses and liverworts) gymnosperms all produce flavodiirons (Flvs), class proteins represented angiosperms; these act mitigate photoinhibition photosystem I. Here, genes specifying two...
