Zinc deficiency is not only the cause of low productivity of crops, but it also results in low zinc content in seeds, which leads to poor dietary zinc intake. To study the effect of zinc foliar application on improving plant yield and seed zinc content for human consumption, chickpea plants were raised in refined sand culture with deficient (0.2 μM) and sufficient (1μM) supply of zinc under gla...

We present data supporting a general role for FERRIC REDICTASE DEFECTIVE3 (FRD3), an efflux transporter of the efficient iron chelator citrate, in maintaining iron homeostasis throughout plant development. In addition to its well-known expression in root, we show that FRD3 is strongly expressed in Arabidopsis thaliana seed and flower. Consistently, frd3 lossof-function mutants are defective in ...

the importance of amaranthus retroflexus pollen in causing respiratory allergy has been well ascertained in many countries including iran with a high positive rate (69%) among iranian allergic patients. the aim of the present study is to identify the allergenic properties of a. retroflexus pollen. sixteen patients with allergy to a. retroflexus pollen were selected for the study. the antigenic ...

Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...

Pollen respiratory allergies have been increasing in prevalence over the last two decades, partly as the result of the impact of climate change. For many allergenic trees, grass and weed species, increased pollen production and prolonged pollination period result in long-term increased abundance of pollen allergens in the atmosphere; earlier shifts of airborne pollen grains and prolonged exposu...

Background: Due to its nutrient content, a variety of spoilage microorganisms can grow in bee pollen, especially when handling practices are not appropriate. So, this survey was designed to assess the physicochemical and microbiological properties of bee pollen collected from Bulgaria. Methods: In June 2014, 13 fresh and 19 dried bee pollen samples were collected from Bulgaria. Water activity ...
