The soils of tropical tasar plantation fields in general are sloppy and are primarily deficient of nutrition due to top soil erosion and constant leaf productivity exploitation to rear tasar silk insect, Antheraea mylitta Drury. The rainfed field of Terminalia tomentosa (W&A) plantation has been evaluated for soil fortification with green mulching through legumes, Sun hemp (Crotalaria juncea), ...

Leaf-color is an effective marker to identify the hybridization of rice. Leaf-color related genes function in chloroplast development and the photosynthetic pigment biosynthesis of higher plants. The ygl7 (yellow-green leaf 7) is a mutant with spontaneous yellow-green leaf phenotype across the whole lifespan but with no change to its yield traits. We cloned gene Ygl7 (Os03g59640) which encodes ...

in order to have a sustainable agriculture it is necessary to use environmental friendly inputs to improve ecological aspects of environment. basil (ocimum basilicum l.) is a medicinal and vegetable crop which is cultivated in different parts of the world. an experiment was conducted at research station, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a complete rand...

Stay-green sorghum plants exhibit greener leaves and stems during the grain-filling period under water-limited conditions compared with their senescent counterparts, resulting in increased grain yield, grain mass, and lodging resistance. Stay-green has been mapped to a number of key chromosomal regions, including Stg1, Stg2, Stg3, and Stg4, but the functions of these individual quantitative tra...

Leaf color in some individuals of Cistus creticus turns transiently to red during winter, while neighboring individuals occupying the same site remain green. We have examined whether anthocyanin accumulation can be associated with variations in photosynthetic and/or photoprotective characteristics between the two phenotypes, rendering the red phenotype more vulnerable to photoinhibition and, ac...

In photosynthesis, the pigments chlorophyll a/b absorb light energy to convert to chemical energy in chloroplasts. Though most enzymes of chlorophyll biosynthesis from glutamyl-tRNA to chlorophyll a/b have been identified, the exact composition and regulation of the multimeric enzyme Mg-protoporphyrin IX monomethyl ester cyclase (MPEC) is largely unknown. In this study, we isolated a rice pale-...

Increasing the duration of leaf photosynthesis during grain filling using slow-senescing functional stay-green phenotypes is a possible route for increasing grain yields in wheat (Triticum aestivum L.). However, delayed senescence may negatively affect nutrient remobilisation and hence reduce grain protein concentrations and grain quality. A novel NAC1-type transcription factor (hereafter TaNAC...

Sixty nine pearlmillet germplasm entries of diverse origin were evaluated for seven quantitative characters and three qualitative characters for their per se performance, variability and genetic divergence. Wider variability was observed for fodder yield and its associating characters along with crude protein content. The GCV estimates were observed to be high for number of leaves per plant, nu...

nowadays, protection of environment and safe agricultural production are an important aims of the sustainable agriculture. also, in attention to abundance of saline soil and water resources in the country, the present research was designed to evaluate pgpr inoculation effect on some morphological and physiological traits of two green bean plant cultivars under salinity stress conditions. a gree...

The pentatricopeptide repeat (PPR) gene family represents one of the largest gene families in higher plants. Accumulating data suggest that PPR proteins play a central and broad role in modulating the expression of organellar genes in plants. Here we report a rice (Oryza sativa) mutant named young seedling albino (ysa) derived from the rice thermo/photoperiod-sensitive genic male-sterile line P...
