Soybean is one of the world’s most important sources of vegetable oil and protein meal. The results of plant breeding efforts have greatly improved the crop characteristics but genetic engineering offers new possibilities. Genetic transformation has tremendous potential in developing improved soybean varieties with desired agronomic traits, which are otherwise difficult to achieve through tradi...

Soybean varieties bred for normal (NM), low-linolenic (LL) or low-saturate (LS) fatty acid composition were collected 20 d prior to harvest. Seed starch structure and functional properties were studied. Soybean starch had small granules (0.5–4.5 lm diameter), and CB-type crystallinity. LL and LS soybean starch had significantly lower absolute amylose than NM soybean. Weight-average amylopectin ...

population density and spatial distribution of thrips tabaci lindeman on seven soybean varieties (williams, tellar, sahar, dpx, l17, sari and zane) and one genotype (ks3494) were studied in tehran region, during 2007. the highest population density of the thrips per leaf was recorded on dpx and on ks3494 (0.810.05 and 0.800.05, respectively). the lowest population density was observed on l17 ...

BACKGROUND Low phosphorus (P) availability is a major constraint to soybean growth and production. Developing P-efficient soybean varieties that can efficiently utilize native P and added P in the soils would be a sustainable and economical approach to soybean production. SCOPE This review summarizes the possible mechanisms for P efficiency and genetic strategies to improve P efficiency in so...

The present investigation was undertaken to study and compare the changes in proximate principals and T 1 content in differently processed mature Indian soy genotypes. Proximate principals as moisture, proteins, carbohydrates, fat, ash, fibre and TI content were assessed in two Indian soybean genotypes viz., NRC-37 and JS335 in mature and after applying simple processing technique (soaking, boi...

The objective of this work was to evaluate the genetic variation of trypsin inhibitor in cultivated (Glycine max L.) and wild (Glycine soja Siebold & Zucc.) soybean varieties. Genetic variations of the Kunitz trypsin inhibitor, represented by a 21‐kD protein (KTI), and of the Bowman‐Birk trypsin–chymotrypsin inhibitor (BBI) were evaluated in cultivated (G. max) and wild (G. soja) soybean variet...

Soybean (Glycine max) seed contain some proteins that are allergenic to humans and animals. However, the concentration of these allergens and their expression variability among germplasms is presently unknown. To address this problem, 10 allergens were quantified from 20 nongenetically modified commercial soybean varieties using parallel, label-free mass spectrometry approaches. Relative quanti...

Shortly after the introduction of Roundup Ready (RR) soybean questions arose whether these varieties and/or glyphosate applications to them alter manganese (Mn) relations compared to conventional soybean varieties. It is well documented that certain cations, including Mn, can reduce the performance of glyphosate when the cations are present in water used as a carrier. The complexes formed betwe...

The present investigation was conducted to study the effect of processing (soaking and germination) and cooking methods (ordinary cooking and autoclaving) on the chemical composition, sugars and phytic of two varieties soybean seeds, Giza, 21 and Giza, 35. The processing and cooking methods caused increase in both protein and crude fiber contents. Meanwhile, crude oil and carbohydrates contents...

introduction: crude vegetable oils contain some quantities of phospholipids. the highest concentration of phospholipids is usually found in crude soybean oil. the presence of phospholipids in the crude and refined oils create undesirable effects on the quality and quantity of the oil during refining operations or use by the consumer. however, if phospholipids are extracted properly from the oil...
