13. Bivalent RNA interference to increase isoflavone biosynthesis in soybean (Glycine max)
In this work, a bivalent RNA interference (RNAi) plant-transformation vector was constructed to silence both the flavanone 3-hydroxylase (F3H) gene and the flavone synthase II (GmFNSII) gene in soybean (Glycine max). Two further unit RNAi vectors were constructed for each of these two genes. RNAi-mediated suppression of these genes effectively regulated flav

14. Biological aspects of Leucothyreus alvarengai Frey and Leucothyreus aff. semipruinosus Ohaus (Coleoptera, Melolonthidae, Rutelinae) in crop succession at central Brazil
Biological aspects of Leucothyreus alvarengai Frey and Leucothyreus aff. semipruinosus Ohaus (Coleoptera, Melolonthidae, Rutelinae) in crop succession at central Brazil. Beetles of the family Melolonthidae make up a large group and some species are considered pests of planted crops. Little information is available on the basic biological aspects of the genus

15. Introduction of the rd29A: AtDREB2A CA gene into soybean (Glycine max L. Merril) and its molecular characterization in leaves and roots during dehydration
The loss of soybean yield to Brazilian producers because of a water deficit in the 2011-2012 season was 12.9%. To reduce such losses, molecular biology techniques, including plant transformation, can be used to insert genes of interest into conventional soybean cultivars to produce lines that are more tolerant to drought. The abscisic acid (ABA)-independent

16. Effect of salt on the growth and metabolism of Glycine max
Soybean plants cultivated with 50, 100 and 200 mM of NaCl, revealed that root growth was less affected by salinity than shoots. Salinity led to a reduction in leaf area and an increase in water content of the roots. These factors could contribute to the adaptation of the plant, improving its hydration. Although nitrate and free amino acid levels were reduced

17. Transcriptome analysis of resistant soybean roots infected by Meloidogyne javanica
Soybean is an important crop for Brazilian agribusiness. However, many factors can limit its production, especially root-knot nematode infection. Studies on the mechanisms employed by the resistant soybean genotypes to prevent infection by these nematodes are of great interest for breeders. For these reasons, the aim of this work is to characterize the trans

18. Subtractive libraries for prospecting differentially expressed genes in the soybean under water deficit
Soybean has a wide range of applications in the industry and, due to its crop potential, its improvement is widely desirable. During drought conditions, soybean crops suffer significant losses in productivity. Therefore, understanding the responses of the soybean under this stress is an effective way of targeting crop improvement techniques. In this study, w

19. A simple, economical and reproducible protein extraction protocol for proteomics studies of soybean roots
Sample preparation is a critical step in two-dimensional gel electrophoresis (2-DE) of plant tissues. Here we describe a phenol/SDS procedure that, although greatly simplified, produced well-resolved and reproducible 2-DE profiles of protein extracts from soybean [Glycine max (L.) Merril] roots. Extractions were made in three replicates using both the origin

20. Method optimization for proteomic analysis of soybean leaf: improvements in identification of new and low-abundance proteins
The most critical step in any proteomic study is protein extraction and sample preparation. Better solubilization increases the separation and resolution of gels, allowing identification of a higher number of proteins and more accurate quantitation of differences in gene expression. Despite the existence of published results for the optimization of proteomic

21. Expression pattern of drought stress marker genes in soybean roots under two water deficit systems
The study of tolerance mechanisms for drought stress in soybean is fundamental to the understanding and development of tolerant varieties. Using in silico analysis, four marker genes involved in the classical ABA-dependent and ABA-independent pathways of drought response were identified in the Glycine max genome in the present work. The expression profiles o

Metabolismo fermentativo em raízes e nódulos de soja sob condições de hipoxia e pós-hipoxia / Fermentative metabolism in soybean roots and nodules under hypoxia and post-hypoxia conditions / Metabolismo fermentativo em raízes e nódulos de soja sob condições de hipoxia e pós-hipoxia / Fermentative metabolism in soybean roots and nodules under hypoxia and post-hypoxia conditions
O metabolismo das plantas reage sensivelmente às mudanças de disponibilidade de oxigênio impostas pelo alagamento. Uma das consequências imediatas da depleção do oxigênio é a ativação do metabolismo anaeróbico e uma redução significativa na produção de energia. Este trabalho teve por objetivo avaliar o metabolismo fermentativo em raízes e nó

23. Interação entre diferentes níveis populacionais iniciais de Pratylenchus brachyurus e cultivares de soja no desenvolvimento da planta e na reprodução do nematóide / Interaction between differents initial population levels of Pratylenchus brachyurus and soybean cultivars in plant growth and nematode reproduction
Due to the significant damage that Pratylenchus brachyurus causes to soybean, this study evaluated different initial populations of this nematode and soybean and investigated the effect of this interaction in plant development and nematode reproduction under greenhouse conditions. The experiment was conducted in completely randomized design as a 6x8 factoria

24. Effect of hydrogen on soybean root growth in a subsurface solution.
A vertical split-root technique was used to evaluate the effects of pH levels in a subsurface solution compartment on root development of soybean (Glycine max (L.)Merr.). The surface root compartment (12cm) was filled with limed and fertilized soil. Treatments in the solution compartment were seven pH levels (3.7, 4.0, 4.3, 4.6, 4.9, 5.2, and 5.5) with 2uM C
