Brassica napus L. is an important oil crop worldwide and is the main raw material for biofuel. Seed weight and seed size are the main contributors to seed yield. DA1 (DA means big in Chinese) is an ubiquitin receptor and negatively regulates seed size. Down-regulation of AtDA1 in Arabidopsis leads to larger seeds and organs by increasing cell proliferation in integuments. In this study, BnDA1 w...

This study was conducted to evaluate the biochemical effects of grape seed extract against dexamethasone-induced hepatic and renal dysfunction in a female albino rat. Twenty-eight adult female rats were divided randomly into four equal groups: Group 1: animals were injected subcutaneously with saline and consider as normal control one. Group 2: animals were injected subcutaneously with dexameth...

drought is one on the most important factors limiting the productivity of spring chickpea in drylands of iran. sixtym genotypes of chickpea from icarda's germplasm accessions, as well as one drought susceptible check (ilc 3279), were sown in spring of 2010 at two locations, sanandaj and maragheh, in the western highlands of iran for one year. the experiment in each location was laid out in a ra...

Cumin (Cuminum cyminum L.) is one of the most important cultivable medicinal plants in Iran and today, it is the second most popular spice in the world after black pepper. It is essential to know the relationships between yield and its components in cumin breeding programs. Therefore, different multivariate statistical analysis was performed on plant characters in cumin to determine th...

Maternal control of seed size in the common bean provides an opportunity to study genotype-independent seed weight effects on early seedling growth and development. We set out to test the hypothesis that the early heterotrophic growth of bean seedlings is determined by both the relative amount of cotyledon storage reserves and the genotype of the seedling, provided the hybrid genotype could be ...

Seed size is a component of grain yield and an important trait in crop domestication. To understand the mechanisms governing seed size in maize (Zea mays), we examined transcriptional and developmental changes during seed development in populations divergently selected for large and small seed size from Krug, a yellow dent maize cultivar. After 30 cycles of selection, seeds of the large seed po...

To understand the gene expression networks controlling soybean seed set and size, transcriptome analyses were performed in three early seed developmental stages, using two genotypes with contrasting seed size. The two-dimensional data set provides a comprehensive and systems-level view on dynamic gene expression networks underpinning soybean seed set and subsequent development. Using pairwise c...

Both ploidy and hybridity affect cell size and growth vigor in plants and animals, but the relative effects of genome dosage and hybridization on biomass, fitness, and gene expression changes have not been systematically examined. Here we performed the first comparative analysis of seed, cell, and flower sizes, starch and chlorophyll content, biomass, and gene expression changes in diploid, tri...

Changes in peroxidase activity was analyzed in developing mustard (Brassica juncea) seed. The activity in soluble and bound fraction was assayed with three hydrogen donors viz. ferulic acid, caffeic acid and chlorogenic acid. Growth was measured in terms of dry weight and water content. Seed dry weight data was fitted to a cubic polynomial equation. The rate of dry matter accumulation was calcu...
