in present study two species of pleurotus with different morphological characteristics were collected from guilan forest and then cultured on mea medium. spawn was prepared on wheat grains and finally all strains were cultivated on rice straw. identification of species was performed by pcr, microscopic and macroscopic characters. results revealed that our local strains are known as pleurotus os...

Wheat, oats, barley, rye, rice, and millet are all considered small grains. These small grains are carbohydrate and vitamin rich and have become food staples for humans and animals worldwide. Small grains have been cultivated by man for thousands of years and through selective breeding, they have become one of the most productive crops grown by man. Small grains have been adapted to grow in nea...

Trace elements (TEs) are vital for the operation of metabolic pathways that promote growth and structural integrity. Paddy soils are often prone to TE limitation due to intensive cultivation and irrigation practices. Apart from this, rice paddies are potentially contaminated with transition metals such as Cd, which are often referred to as toxic TEs. Deficiency of TEs in the soil not only delay...

There are technical difficulties in obtaining intact sections of cereal grains in which mature cells and their subcellular structures are well preserved. Here we describe a simple method for sectioning hard mature rice grains. It makes possible accurate localization of storage proteins in high-quality histological sections of rice endosperm.

Weissella oryzae was originally isolated from fermented rice grains. Here we report the draft genome sequence of the type strain of W. oryzae. This first report on the genomic sequence of this species may help identify the mechanisms underlying bacterial adaptation to the ecological niche of fermented rice grains.

Numerous studies have shown growing information indicating the contribution of food to the dietary exposure of arsenic (As) through consumption of different food items in many different regions over the world. However, few review papers with regard to As in Sri Lankan foods are available in databases. Thus, a critical review and assessment of a number of local studies on total As concentrations...

Fertilizers usually enhance potassium (K) content and other naturally occurring radioactive materials in agricultural fields that eventually enter the human food chain through plants. In this study, pot-grown rice plants planted in soil that is relatively high in natural radioactive content was used to estimate the individual influence of fertilizer applications on the uptake of 226Ra, 232Th, a...

The aim of this work was to investigate the suitable rice varieties for developing pharmaceutical buccal films. Two rice varieties with extreme difference in amylose content were used. Rice powders were chemically modified to yield the carboxymethyl rice prior to film preparation. Scanning electron microscope (SEM) and X-ray diffractometer (XRD) were used to investigate the solid structure of r...

Rice grains are rich in starch but low in protein with very low level of both lysine and threonine. Thus, it is important to further improve protein quality and quantity, especially to increase lysine and threonine content in rice grains. We artificially synthesized two new genes by fusing endogenous rice genes with lysine (K)/threonine (T) motif (TKTKK) coding sequences. They were designated a...

Saliva-based tests are not new. The Chinese used saliva for an ancient polygraph called the rice test, in which an interrogator placed grains of dry rice into the mouth of a suspect and asked the suspect to spit out the rice. If the grains of rice stuck to the mouth of the suspect, stressinduced xerostomia was assumed—and therefore the suspect was guilty. Fortunately, over the past 3000 years, ...
