beta conglycinin/arabidopsis

beta-conglycinin, a major component of seed-storage proteins in soybean, comprises three subunits: alpha, alpha', and beta. Expression of these genes is spatially regulated in a stringent manner and occurs during seed development. To understand the mechanisms that control expression of the alpha

Differentiation into specific embryo cell types correlates with the processes that lead to the accumulation of seed storage proteins in plants. The alpha subunit of beta-conglycinin, a major component of seed storage proteins in soybean, accumulates at a higher level in cotyledons than in the

The composition of seed storage proteins is regulated by sulfur and nitrogen supplies. Under conditions of a low sulfur-to-nitrogen ratio, accumulation of the beta-subunit of beta-conglycinin, a sulfur-poor seed storage protein of soybean (Glycine max [L.] Merr.), is elevated, whereas that of

Among the three subunits of [beta]-conglycinin, the 7S seed storage protein of soybean (Glycine max [L.] Merr.), expression of the [beta] subunit gene is unique. Accumulation of the [beta] subunit is enhanced in sulfate-deficient soybean plants, and its mRNA levels increase when abscisic acid (ABA)

The protein disulfide isomerase is known to play important roles in the folding of nascent polypeptides and in the formation of disulfide bonds in the endoplasmic reticulum (ER). In this study, we cloned a gene of a novel protein disulfide isomerase family from soybean leaf (Glycine max L. Merrill.

Transgenic expression of genes encoding the alpha' and beta subunits of beta-conglycinin, one of the major seed storage proteins of soybean (Glycine max [L.] Merr.), was analyzed in Arabidopsis thaliana (L.) Heynh. under conditions of sulfate deficiency. Temporal patterns of expression of both the

Two Arabidopsis thaliana genes have been shown to function in vacuolar sorting of seed storage proteins: a vacuolar sorting receptor, VSR1/ATELP1, and a retromer component, MAIGO1 (MAG1)/VPS29. Here, we show an efficient and simple method for isolating vacuolar sorting mutants of Arabidopsis. The

Different combinations of three rate-limiting enzymes in phytosterol biosynthesis, the Arabidopsis thaliana hydroxyl methylglutaryl CoA1 (HMGR1) catalytic subunit linked to either constitutive or seed-specific β-conglycinin promoter, and the Glycine max sterol methyltransferase1 (SMT1) and sterol

Expression of the gene encoding the beta subunit of beta-conglycinin, a major soybean seed storage protein, is upregulated by sulfur deficiency and downregulated by methionine (Met). The tissue-specificity of these regulatory mechanisms was studied using a sulfate-responsive region (beta(SR)) from

Effects of plant hormones on a sulfur-deficiency responsive element (betaSR) from the promoter region of the beta subunit gene of beta-conglycinin, a major seed storage protein of soybean, were investigated using transgenic Arabidopsis thaliana. Among the hormones tested, the cytokinins,

Plant seeds accumulate large amounts of protein and carbohydrate as storage reserves during maturation. Thus, understanding the genetic control of embryo and seed development may provide bioengineering tools for yield improvement. In this study, we report the identification of Retarded Embryo

Two relatively rare fatty acids, gamma-linolenic acid (GLA) and stearidonic acid (STA), have attracted much interest due to their nutraceutical and pharmaceutical potential. STA, in particular, has been considered a valuable alternative source for omega-3 fatty acids due to its enhanced conversion
