Trigonella Foenum Graecum L

A qualitative as well as quantitative categorization of seed storage proteins profiles of 23 genotypes of Trigonella foenum- graecum L. were performed by using sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) for exploring the level of genetic discrepancy at seed storage protein level. Total soluble proteins were resolved on 10% resolving gel. A dendrogram was constructed on the basis of weight of seed storage proteins, which divide total genotypes into two groups further classified into different sub groups containing different genotypes in them. The bands obtained from gel electrophoresis can serve as a potent tool in discrimination of different genotypes on the basis of their protein content. Proteins with molecular weight 66, 43 and 35 kDa were found in all the genotypes except Fgk-76, PR, Rmt-303, PEB and Rmt-361, The 43 kDa protein band was found missing in Fgk-67, AFg-2, AM-2, AFg-4, Fgk-73, although the protein with 35 kDa weight was present in all the genotypes but not in Rmt-303 same as 63 kDa which is not present in Fgk-70 and 55 kDa protein band was found missing in Fgk-67, Afg-4 and Rmt-361.

Total seed storage protein profiles of 74 mungbean land races, three wild accessions and a popular variety ‘Jyoti’ of Odisha were analysed by Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). 32 genotypes could be clearly identified based on genotype-specific seed protein fingerprints while rest of the test genotypes were categorized into eight protein types. Genotypes included in each protein type had 100% homology and some of these could be duplicates. In this pursuit, a few specific polypeptide markers have been detected for identification of the land races/ genotypes. Dendrogram based on electrophoretic data clustered the genotypes into seven groups at 70% phenon level. Paralakhemundi local, Samarjhola local and Phulbani local-D; and three wild accessions (TCR 20, TCR 213 and TCR 243) were comparatively divergent from other genotypes. Besides, Jyoti, Kalahandi local 2A, Sikri local, kodala local A and TCR 20 were identified to be protein rich with high seed yield. TCR 20 being morphologically similar to mungbean, moderately high protein content and high yielding as well as resistant to drought and bruchids; it may serve as a valuable source genotype in recombination breeding

The objective of our study was to determine the composition of high-molecular weight-glutenin subunits (HMW-GS) in 120 cultivars of common wheat (Triticum aestivum L.). Fourteen alleles and 34 allelic compositions were detected using sodium dodecyl sulphate-polyacrylamide gel electrophoresis. The most frequent HMW-GS alleles at the Glu-A1, Glu-B1 and Glu-D1 loci were null (57.1%), 7+9 (43.3%) and 5+10 (61.9%), respectively. However, low-frequency HMW-GS alleles were also observed, such as 13+16, 20, 21, 7 and 18, encoded by the Glu-B1 locus, and 4+12, encoded by the Glu-D1 locus. The wheat–rye 1BL.1RS translocation was identified in 25 cultivars, using acid polyacrylamide gel electrophoresis. The Glu-score varied greatly, and some lines reached the maximum value of 10.

Bambara groundnut (Vigna subterranea) is a leguminous crop that is considered underutilized and has previously received little research attention. Variability in a number of physiological factors, including germination rate, widely affects its production. Seed storage protein, its fractions and protein profile of six Bambara groundnut local landraces were studied to assess their genetic relatedness. Total seed storage protein and its fractions were estimated by Bradford’s method. SDS-PAGE analysis was used to evaluate storage protein profile. The results showed significant differences (p<0.05) in protein contents among the landraces. The major seed storage proteins were found to be globulins (0.048 to 0.088mg/mL ), albumins (0.023 to 0.038mg/mL ), glutelins (0.007 to 0.013mg/mL ) and prolamins (0.002 to 0.004mg/mL ). Five peptide bands were detected with molecular weights corresponding to 97.4 kDa, 45 kDa, 29 kDa, 20.1 kDa and 18 kDa, respectively. Three peptide bands corresponding to 97.4 kDa, 45 kDa and 18 kDa were detected in all the landraces and two peptide bands between 29 kDa and 20.1 kDa were detected in five landraces. Dendrogram generated by UPGMA grouped the six landraces into one major cluster with two sub-clusters. The observed diversity in storage protein pattern of the landraces indicated their potential as materials for crop improvement.

AbstractThe genetic diversity of common bean accessions were assessed using seed storage protein markers. At regional level, accessions from the two major growing regions showed the highest level of gene diversity (H = 0.322, I = 0.485, and H = 0.312, I = 0.473), which can be exploited for the future improvement of the crop. Based on phaseolin, the major storage protein in common bean, the majority of the accessions (86%) were grouped under Mesoamerican gene pool. Seed proteins were also used to differentiate various Phaseolus species, indicating the usefulness of seed storage proteins in species identification in this genus.

Endomembrane System

Rice synthesizes and accumulates high levels of 2 distinct classes of seed storage proteins and sorts them to separate intracellular compartments, making it an ideal model system for studying the mechanisms of storage protein synthesis, transport, and deposition. In rice, RNA localization dictates the initial site of storage protein synthesis on specific subdomains of the cortical endoplasmic reticulum (ER), and there is a direct relation between the RNA localization site and the final destination of the encoded protein within the endomembrane system. Current data support the existence of 3 parallel RNA localization pathways leading from the nucleus to the actively synthesizing cortical ER. Additional pathways may exist for the synthesis of cytoplasmic and nuclear-encoded proteins targeted to organelles, the latter located in a stratified arrangement in developing endosperm cells. The study of rice mutants, which accumulate unprocessed glutelin precursors, indicates that these multiple pathways prevent nonproductive interactions between different classes of storage proteins that would otherwise disrupt protein sorting. Indeed, it appears that the prevention of disruptive interactions between different classes of storage proteins plays a key role in their biosynthesis in rice. In addition to highlighting the unique features of the plant endomembrane system and describing the relation between RNA and protein localization, this minireview will attempt to address a number of questions raised by recent studies on these processes.Key words: mRNA localization, protein localization, endomembrane system, seed storage proteins, rice.

Trigonella Foenum Graecum L

The 96 genotypes of Trigonella foenum-graecum L. (Fenugreek) were estimated by using Sodium Dodecyl Sulphate Poly Acrylamide Gel Electrophoresis (SDS-PAGE). The accessions were maintained from diverse ecological areas of the world. Total seed storage proteins were electrophoresis on 12.5% polyacrylamide gels. A total of 17 protein bands were detected, of which seven were highly polymorphic and six were moderate polymorphic and four were low polymorphic with molecular weight extending from of ~15 to ~180 kDa. The dendrogram based on similarity matrix using Unweighted Pair Group Method with Arithmetic Mean (UPGMA) divided all the genotypes into four major clusters i.e., I, II, III and IV comprising 51, 24, 10 and 11 accessions, respectively. Although limited genetic diversity was detected amongst known germplasm but the presence/absence of polymorphic bands revealed a significant variances among different Trigonella genotypes. The differences exposed in this project work should be oppressed for the future breeding prospective of Trigonella genotypes by using other advanced molecular techniques. The SDS-PAGE per se seems inadequate tool for such kind of analysis, and may be integrated with other genetic and sequence based approaches for more precise estimation of the genetic variability within closely related accessions. Our results provide baseline for obtaining locally adapted and improved cultivars of fenugreek in Pakistan.

In the present study, phytochemical contents of 25 moth bean (Vigna aconitifolia) seed accessions were evaluated. This includes protease inhibitors, phytic acid, radical scavenging activity, and tannins. The studies revealed significant variation in the contents of theses phytochemicals. Presence of photochemical composition was correlated with seed storage proteins like albumin and globulin. Qualitative identification of total seed storage protein abundance across two related moth bean accessions using two-dimensional gel electrophoresis (2D-GE) was performed. Over 20 individual protein fractions were distributed over the gel as a series of spots in two moth bean accessions. Seed proteome accumulated spots of high intensity over a broad range of pI values of 3–10 in a molecular weight range of 11–170 kDa. In both seed accessions maximum protein spots are seen in the pI range of 6–8.

The objective of this work was to quantify the accumulation of the major seed storage protein subunits, β-conglycinin and glycinin, and how they influence yield and protein and oil contents in high-protein soybean genotypes. The relative accumulation of subunits was calculated by scanning SDS-PAGE gels using densitometry. The protein content of the tested genotypes was higher than control cultivar in the same maturity group. Several genotypes with improved protein content and with unchanged yield or oil content were developed as a result of new breeding initiatives. This research confirmed that high-protein cultivars accumulate higher amounts of glycinin and β-conglycinin. Genotypes KO5427, KO5428, and KO5429, which accumulated lower quantities of all subunits of glycinin and β-conglycinin, were the only exceptions. Attention should be given to genotypes KO5314 and KO5317, which accumulated significantly higher amounts of both subunits of glycinin, and to genotypes KO5425, KO5319, KO539 and KO536, which accumulated significantly higher amounts of β-conglycinin subunits. These findings suggest that some of the tested genotypes could be beneficial in different breeding programs aimed at the production of agronomically viable plants, yielding high-protein seed with specific composition of storage proteins for specific food applications.
