WebOur results reveal that substantial variation for root phenotypes exists among and within Phaseolus taxa, notably for phenes such as basal root number, basal root whorl number, root hair length, root hair density, metaxylem vessel number, and total cross-sectional area. The development of crop genotypes with enhanced phosphorus acquisition efficiency (PAE) represents an important opportunity to improve food security in developing nations, where crop yields are severely limited by low phosphorus availability (Lynch, 2007). Simple screening for yield in low-phosphorus soils has not … See more Plant growth in the vast majority of terrestrial ecosystems is limited by low phosphorus availability. Over 70% of all terrestrial biomass occurs in low-phosphorus … See more Phosphate is highly immobile in soil, because it reacts with many chemical and biological soil constituents. Plant strategies to acquire phosphorus are therefore … See more The value of a phene for phosphorus acquisition may depend on the expression of other phenes in the plant phenotype. Such interactions may be synergistic, … See more
