| characterization of soybean genetically modified for drought tolerance in field conditions. | drought is one of the most stressful environmental factor causing yield and economic losses in many soybean-producing regions. in the last decades, transcription factors (tfs) are being used to develop genetically modified plants more tolerant to abiotic stresses. dehydration responsive element binding (dreb) and aba-responsive element-binding (areb) tfs were introduced in soybean showing improved drought tolerance, under controlled conditions. however, these results may not be representative of ... | 2017 | 28443101 |
| functional analysis of the gmesr1 gene associated with soybean regeneration. | plant regeneration can occur via in vitro tissue culture through somatic embryogenesis or de novo shoot organogenesis. transformation of soybean (glycine max) is difficult, hence optimization of the transformation system for soybean regeneration is required. this study investigated enhancer of shoot regeneration 1 (gmesr1), a soybean transcription factor that targets regeneration-associated genes. sequence analysis showed that gmesr1 contained a conserved 57 amino acid apetala 2 (ap2)/ethylene r ... | 2017 | 28403182 |
| hierarchically aligning 10 legume genomes establishes a family-level genomics platform. | mainly due to their economic importance, genomes of 10 legumes, including soybean (glycine max), wild peanut (arachis duranensis and arachis ipaensis), and barrel medic (medicago truncatula), have been sequenced. however, a family-level comparative genomics analysis has been unavailable. with grape (vitis vinifera) and selected legume genomes as outgroups, we managed to perform a hierarchical and event-related alignment of these genomes and deconvoluted layers of homologous regions produced by a ... | 2017 | 28325848 |
| expression of cyanobacterial fbp/sbpase in soybean prevents yield depression under future climate conditions. | predictions suggest that current crop production needs to double by 2050 to meet global food and energy demands. based on theory and experimental studies, overexpression of the photosynthetic enzyme sedoheptulose-1,7-bisphosphatase (sbpase) is expected to enhance c3 crop photosynthesis and yields. here we test how expression of the cyanobacterial, bifunctional fructose-1,6/sedoheptulose-1,7-bisphosphatase (fbp/sbpase) affects carbon assimilation and seed yield (sy) in a major crop (soybean, glyc ... | 2017 | 28204603 |
| ca2+ and aminoguanidine on γ-aminobutyric acid accumulation in germinating soybean under hypoxia-nacl stress. | gamma-aminobutyric acid (gaba), a nonproteinous amino acid with some benefits on human health, is synthesized by gaba-shunt and the polyamine degradation pathway in plants. the regulation of ca2+ and aminoguanidine on gaba accumulation in germinating soybean (glycine max l.) under hypoxia-nacl stress was investigated in this study. exogenous ca2+ increased gaba content significantly by enhancing glutamate decarboxylase gene expression and its activity. addition of ethylene glycol tetra-acetic ac ... | 2015 | 28911384 |
| bioassay versus chemical assay: measuring the impact of induced and constitutive resistance on herbivores in the field. | studies of induced plant resistance usually either examine physiological/chemical mechanisms or explore the ecological and evolutionary role of induced resistance. to connect these two methods of study, data are needed that address the relationships between plant chemistry and effects of induced resistance on herbivores under field conditions. in this paper we combine the results of a greenhouse experiment and a field experiment to try to make such a connection. levels of induced and constitutiv ... | 2002 | 28547688 |
| characterization of the laser-induced blue, green and red fluorescence signatures of leaves of wheat and soybean grown under different irradiance. | the blue, green and red fluorescence emission of green wheat (triticum aestivum l. var. rector) and soybean leaves (glycine max l. var. maple arrow) as induced by uv light (nitrogen laser: 337 nm) was determined in a phytochamber and in plants grown in the field. the fluorescence emission spectra show a blue maximum near 450 nm, a green shoulder near 530 nm and the two red chlorophyll fluorescence maxima near 690 and 735 nm. the ratio of blue to red fluorescence, f450/f690, exhibited a clear cor ... | 1993 | 28741762 |
