Tolerance to low oxygen availability is likely to be due to the interaction of several factors. Sugar availability is one of the elements required to support anaerobic metabolism. In cereal grains the availability of soluble sugars is limited, while starch is stored in large amounts. Degradation of starch under anoxia is therefore needed to avoid sugar starvation leading to rapid cell death. Th...

The continental bio-cycling of silicon (Si) plays a key role in global Si cycle and as such partly controls global carbon (C) budget through nutrition of marine and terrestrial biota, accumulation of phytolith-occluded organic carbon (PhytOC) and weathering of silicate minerals. Despite the key role of elemental composition of phytoliths on their solubility in soils, the impact of plant cultiva...

in order to evaluate the relationship between morphological characters in rice lines two populations at f3 generation were grown in research field of agricultural sciences and natural resource university, sari, iran, during 2012. statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...

Stable isotopic compositions and elemental contents of the H, C, N, and O in 163 rice samples were analyzed. The samples were taken from three different farming countries; Japan (n = 103), United States of America (n = 30), and Australia (n = 21), in addition of Asian rice samples from Thailand (n = 2), Vietnam (n = 1), and China (n = 6) as comparison. They were mostly short grain samples known...

background: aflatoxins are toxic fungal metabolites enable to contaminate a wide range of natural substrates. this contamination can be host-specific for different plant species. in this study, the ability of a toxigenic aspergillus parasiticus to produce various aflatoxins on major iranian cereals was evaluated with special focus on plant susceptibility to toxin production at cultivar level. m...

rice is a main food for iranian people and has an important role in providing food security. regarding the population growth, increase of rice production and reduction of losses have special importance in prevention of rice import. rice losses in the harvest stage are the highest through the whole production period of this crop and hence the reduction of these losses is necessary. provision of ...

Diabetes is a lifestyle disease, and its prevention and treatment are extremely important. Since Hoku243 presents fewer short-branched glucans and more long chains in the amylopectin starch, its starch is resistant to gelatinization and the boiled rice grains are non-sticky and brittle. The prevention of abrupt increases in postprandial blood glucose level (BGL) after consumption of Hoku243 (pr...
