Pigmented Soybean (Glycine max) Seed Coats Accumulate Proanthocyanidins during Development.
The dominant I gene inhibits accumulation of anthocyanin pigments in the epidermal layer of soybean (Glycine max) seed coats. Seed-coat color is also influenced by the R locus and by the pubescence color alleles (T, tawny; t, gray). Protein and RNA from cultivars with black (i,R,T) and brown (i,r,T) seed coats are difficult to extract. To determine the nature of the interfering plant products, ...
متن کاملThe Transition from Primary siRNAs to Amplified Secondary siRNAs That Regulate Chalcone Synthase During Development of Glycine max Seed Coats
The I locus is a 27-kb inverted repeat cluster of chalcone synthase genes CHS1-3-4 that mediates siRNA down-regulation of CHS7 and CHS8 target mRNAs during seed development leading to yellow seed coats lacking anthocyanin pigments. Here, we report small RNA sequencing of ten stages of seed development from a few days post fertilization through maturity, revealing the amplification from primary ...
متن کاملProtein Synthesis during Natural and Precocious Soybean Seed (Glycine max [L.] Merr.) Maturation.
Protein synthesis was studied during precocious and natural soybean seed (Glycine max [L.] Merr.) maturation. Developing seeds harvested 35 days after flowering were precociously matured through controlled dehydration. Total soluble proteins and proteins labeled with [(35)S]methionine were extracted from control, developing seeds and from precociously and naturally matured seeds and were analyz...
متن کاملSoybean [Glycine max (L.) Merr].
In this chapter we describe an Agrobacterium tumefaciens transformation method of soybean that utilizes mature half seeds and regeneration from the cotyledonary node region. This method results in fertile transformed soybean plants and transgenic seed in approximately 9 months. Using mature half seeds as starting material has proven to be a reliable method that does not require additional wound...
متن کاملAssessment of seed storage protein composition of six Iranian adopted soybean cultivars [Glycine max (L.) Merrill.]
Seed protein quality is an important topic in the production of soybean. The quality of soybean proteins is limited by anti-nutrient proteins and low levels of essential sulfur amino acids. In this study, protein content and solubility of six cultivars were evaluated and seed storage proteins were analyzed using SDS-PAGE and scanning densitometry. The results showed that seed storage protein ba...
