In amaranth grains (Amaranthus hypochondriacus L. and Amaranthus cruentus L.), there were two albumin (Alb) fractions, Alb-1 and Alb-2; Alb-1 was extracted with water or 0.5 M NaCl, and Alb-2 was extracted with water after extracting Alb-1 and globulin. The amount of Alb-2 comprised about 30% of the

Although thionins and 2S albumins are generally considered as storage proteins, both classes of seed proteins are known to inhibit the growth of pathogenic fungi. We have now found that the wheat (Triticum aestivum L.) or barley (Hordeum vulgare L.) thionin concentration required for 50% inhibition

Incorporation of (32)P into nucleic acids in barley plants infected with bromegrass mosaic virus (BMV) was analyzed by chromatography on methylated albumin kieselguhr (MAK) columns. Treatment with actinomycin D reduced the synthesis of ribosomal ribonucleic acid (RNA) to low levels and allowed the

We analyzed the effect of Fusarium graminearum infection on field-grown naked barley (Hordeum vulgare nudum). The ears were inoculated with F. graminearum spores during anthesis. In the course of ripening, grains in five phenological growth stages of naked barley from milk ripe to plant death were

The genetic associations and differences of four protein fractions were investigated in Tibetan wild barley. Albumin, globulin and hordein contents were under genetic control probably via multiple genes/quantitative trait loci. A correlation analysis showed that globulin was significantly associated

Optically active forms of abscisic acid (ABA) and their oxygenated metabolites were tested for their biological activity by examining the effects of the compounds on the reversal of gibberellic acid-induced [alpha]-amylase activity in barley (Hordeum vulgare cv Himalaya) aleurone layers and the

High malting quality of barley (Hordeum vulgare L.) relies on many traits, such as beta-amylase and limit dextrinase activities and beta-glucan and protein fraction contents. In this study, interval mapping was utilized to detect quantitative trait loci (QTLs) affecting these malting quality

Barley grain protein content (GPC) is an important quality factor that determines grain end-use value. The synthesis and accumulation of grain protein is highly dependent on the availability of nitrogen fertilizer, and it is important to understand the underlying control mechanisms of this. In the

Extraction conditions, separation conditions, and capillary rinsing protocols were optimized for the separation of barley hordeins by free zone capillary electrophoresis. Stable hordein extracts were obtained with a single 5 min extraction after the albumins and globulins were removed. Hordeins had

The maturation of the 2S albumin, napin, in Brassica napus L. involves removal of an amino-terminal and an internal propeptide. Pulse-chase experiments with B. napus embryos showed that intermediates are detectable during the pronapin processing. Intact pronapin was expressed by baculovirus in

Among the C1A cysteine proteases, the plant cathepsin F-like group has been poorly studied. This paper describes the molecular and functional characterization of the HvPap-1 cathepsin F-like protein from barley. This peptidase is N-glycosylated and has to be processed to become active by its own

Grain phytochemical profiles were compared in Tibetan wild barley XZ5 (drought-tolerant), XZ16 (salinity/aluminum-tolerant) and cv CM72 (salinity-tolerant) in response to drought and salinity alone and combination (D+S) during anthesis. Total antioxidant capacity assessed by determining

Peptides released from oat, buckwheat, and highland barley proteins were examined for their in vitro inhibitory effects on dipeptidyl peptidase IV (DPP4), an enzyme that deactivates incretin hormones involved in insulin secretion. All of the hydrolysates exhibited DPP4 inhibitory activities, with

Citrate uptake into barley (Hordeum vulgare L.) mesophyll vacuoles was found to be saturable with a K m of about 200 μM. Uptake appears to occur via the citrate(3-) form, as indicated by concentration-dependent uptake studies at different pHs. Free citrate and not the Mg-citrate complex was taken up

A protein of 80 kD from developing pea (Pisum sativum) cotyledons has previously been shown to exhibit characteristics of a vacuolar targeting receptor by means of its affinity for the amino-terminal vacuolar targeting sequence of proaleurain from barley (Hordeum vulgare). In this report we show
