A standard description of growth stages for crops/plants is necessary not only for determining and improving cultural practices, but also to facilitate enhanced communication among producers, researchers, and educators. It also could help in unifying experimental results. Many different descriptions of growth stages are currently available for many crops, but there are no codes for sesame (Sesa...

Despite substantial evidence on the essential roles of cell wall invertase (CWIN) in seed filling, it remains largely unknown how CWIN exerts its regulation early in seed development, a critical stage that sets yield potential. To fill this knowledge gap, we systematically examined the spatial and temporal expression patterns of a major CWIN gene, GhCWIN1, in cotton (Gossypium hirsutum) seeds f...

Pex3p and Pex19p are key players in the post-translational import of peroxisomal membrane proteins. New data suggest that these peroxins act in tandem, Pex19p as a cytosolic chaperone and import receptor for peroxisomal membrane proteins, and Pex3p as docking factor at the peroxisomal membrane.

1. Seed dispersal is a critical life stage of plants, yet accurate measurement of dispersal distances has been difficult in natural systems. Genetic techniques for matching dispersed seeds to maternal trees provide valuable data on dispersal events. Questions remain regarding how best to estimate the population seed dispersal distance distributions from such data and how these estimates compare...

Meiosis, the key step of sexual reproduction, persists in facultative apomictic plants functional to some extent. However, it still remains unclear how and why proportions of reproductive pathways vary under different environmental stress conditions. We hypothesized that oxidative stress mediates alterations of developmental pathways. In apomictic plants we expected that megasporogenesis, the s...

Ten yearling steers weighing 270-360 kg died acutely after eating early seed pod stage Lupinus argenteus (silvery lupine) containing high levels of piperidine alkaloids, including ammodendrine and N-methylammodendrine. Reduced availability of Quality feed from range moderately depleted of Quality grasses appeared a major factor in causing the cattle to graze lupine. Proximate analysis of whole ...

in order to investigate factors affecting on seed germinating of london rocket (sisymbrium irio), lab experiments were set up in 2011 at the payamenoor university, mashhad, khorasan razavi province. effect of different concentrations of gibberellic acid (ga3) and cytokinin, wet and dry prechilling duration, hydrogen peroxide duration, ethanol, salt and osmotic stress and burial depth on seed ge...
