Whole plant transpiration responses of common bean (Phaseolus vulgaris L.) to drying soil: Water channels and transcription factors.

Common bean (Phaseolus vulgaris L.) is the main legume crop for direct human consumption worldwide. Among abiotic factors affecting common bean, drought is the most limiting.

Characterization of genetic diversity and identification of genetic loci associated with carbon allocation in N fixing soybean.

Background: Efficient capture and use of resources is critical for optimal plant growth and productivity. Both shoot and root growth are essential for resource acquisition, namely light and CO by the shoot and water and mineral nutrients by roots. Soybean [Glycine max (L.

Association mapping for water use efficiency in soybean identifies previously reported and novel loci and permits genomic prediction.

Soybean is a major legume crop cultivated globally due to the high quality and quantity of its seed protein and oil. However, drought stress is the most significant factor that decreases soybean yield, and more than 90% of US soybean acreage is dependent on rainfall. Water use efficiency (WUE) is positively correlated with the carbon isotopic ratio C/C (C13 ratio) and selecting soybean varieties for high C13 ratio may enhance WUE and help improve tolerance to drought.

Inhibitory effects of -cinnamoyltyramine on growth of invasive weeds and weedy rice.

-cinnamoyltyramine (NTCT) has been identified from an allelopathic Vietnamese rice accession OM 5930. This study employed bioassays to analyze NTCT's effects on shoot and root growth of multiple test and weed species. NTCT demonstrated potent inhibitory effects on cress, lettuce, canola, palmer amaranth, timothy, barnyardgrass, red sprangletop, and weedy rice, with increasing concentrations leading to substantial reductions in growth in all species.

Redesigning soybean with improved oil and meal traits.

Soybean seed oil and meal composition traits can be combined without interference to provide additional value to the crop. Soybean [Glycine max (L.) Merr.
