(Submitter supplied) As an important adaptation to drought stress, several agronomic species, such as soybean and maize, can maintain the primary root substantial elongation rates at low water potentials, whereas shoot growth stops completely. In soybean, kinematic characterization of the spatial patterns of cell expansion within the root elongation zone showed that at low water potentials, elongation rates were preferentially maintained toward the root apex but were progressively inhibited at more basal locations, resulting in a shortened growth zone. more...

(Submitter supplied) Soybean aphids are phloem-feeding pests that can cause significant yield losses in soybean plants. Soybean aphids thrive on susceptible soybean lines but not on resistant lines. Aphids do not normally kill their host and colonize plants for long periods of time, up to several months in soybean. However, our knowledge of plant responses to long-term aphid colonization is very limited. We used microarrays to characterize the soybean plant's transcriptional response against aphids in two related cultivars, a susceptible line and a resistant line with the Rag1 aphid-resistance gene. more...

(Submitter supplied) Chinese soybean (Glycine max (L.) Merr.) cultivars Rsmv1 and Ssmv1 were used for soybean mosaic virus (SMV) resistance genes screening. The Rsmv1 cultivar was highly-resistant to SMV but the Ssmv1 cultivar was highly-susceptible. We used microarrays to detail the global programme of gene expression underlying SMV inoculation and identified distinct expression genes between Rsmv1 and Ssmv1.

(Submitter supplied) Low temperature stress in a number of African countries, such as Botswana, at night can effect the growth and development of bambara groundnut, leading to losses in potential crop yield. Therefore, we made an attempt to identify and analyze the genes and gene modules associated with low temperature stress response in bambara groundnut using the cross-species microarray technique, as bambara groundnut has no microarray chip, coupled with network-based analysis.

(Submitter supplied) Environmental stresses such as drought, salinity and both high and low temperature are frequently faced by crops all over the world and can be considered major limiting factors for plant geographical distribution and productivity. Breeding has allowed creation of crops more adapted to some of the adverse environmental conditions and to overcome the geographical limitation without major consequences to productivity. more...

(Submitter supplied) The temporal expression profile of Glycine max seeds was carried out to identify genes that are differentially expressed (DE) during seed development. Using the Affymetrix chip, we have for the first time provided a holistic view of the transcriptional landscape during seed development in four different developmental stages in Glycine max. cv. Pusa 16. The analysis of the differential expression patterns and functional category enrichment of DE genes highlighted specific and common significant coordination and enrichment of various biological processes during seed development which have led to the identification of few candidate genes related to inositol metabolism and especially in phytate biosynthesis. more...

(Submitter supplied) Soybean is a rich source of protein and oil and a primary feedstock for biodiesel production. Previous research on soybean indicated that protein, oil and yield are controlled quantitatively in soybean seeds. However, genetic mechanisms controlling seed composition and yield in soybean remain unknown. We used Affymetrix Soybean GeneChips® to identify genes that are differentially expressed between developing seeds of the Minsoy and Archer soybean varieties, which differ in seed weight, yield, protein content and oil content. more...

(Submitter supplied) Developing Evans seeds at 25, 30, 40, 45 and 50 days after flowering (DAF) were harvested and analyzed to gain insights as to the biochemical program that determines soybean seed development. We used microarrays to detail the global programme of gene expression underlying seed development and identified distinct classes of genes with changed expression during this process.

(Submitter supplied) The interaction between soybean and its destructive insect (cotton worm) is complicated. In this paper, the timecourse of induced responses to cotton worm were characterized in two soybean lines, suggesting complex results with different timepoints of peak induced resistance in resistant (WX) and susceptible (NN) soybean lines. To get a better understanding of induced resistant mechanisms of soybean against herbivory, two sets of transcriptome profiles of WX and NN at their peak induced resistant timepoints were compared by microarrays

(Submitter supplied) BiP overexpression confers resistance to drought, through an as yet unknown mechanism that is related to ER functioning, has been described that the delay in leaf senescence by BiP overexpression might relate to the absence of the response to drought. We used microarrays to detail the global programme of gene expression underlying in soybean leaves overexpressing BiP and with different water potentials to elucidate the mechanisms by which BiP protects plant cells against cell death induced by dehydration.

(Submitter supplied) The autoregulation of mycorrhization (AOM) describes a plant regulatory mechanism that limits the number of infection events by arbuscular mycorrhizal fungi. The key signal mediator is a receptor kinase (GmNARK) that acts in the shoots. Early signals of the mycorrhizal symbiosis induce a root-derived signal that activates GmNARK in the shoot finally leading to a systemic repression of subsequent infections in the root. more...

(Submitter supplied) The paraveinal mesophyll (PVM) of soybean leaves is a layer of laterally expanded cells sandwiched between the palisade and spongy mesophyll chlorenchyma. The vacuoles of PVM cells contain an abundance of a putative vegetative storage protein, VSP (α, β). VSP is is constitutively produced, but is up-regulated during sink limitation experiments involving flower, fruit, or vegetative bud removal. Soybean vegetative lipoxygenases (Vlx), consisting of 5 isozymes (Vlx, A-D), have been identified as potential storage proteins because they accumulate to high levels with experimental sink limitation and have been co-localized with VSP to the vacuoles of PVM cells. more...
