Factors affecting root depth of Pines Root … WebIdentification of root phenes improving P capture by physiological research enabled breeding to select for specific phene states rather than coarse yield-based metrics. This selection process targeted root phenes such as basal root whorl number (BRWN), basal root growth angle (BRGA) and long, dense root hairs.

WebArchitecture phenes can reduce root costs by reducing competition for phosphorus within and among plants, and by regulating biomass allocation to root classes of varying metabolic cost. Morphological phenes such as root hairs can increase phosphorus acquisition at min- imal metabolic expense. Phenes are the fundamental units of the phenotype that are both unique and elementary to a given level of biological organization. A phene state is the outcome of complex synergistic developmental systems, influenced by genes and gene products, as well as the environment. Root architectural and anatomical phenes determine the temporal and spatial distribution of root foraging in specific soil domains, and therefore affect resource capture. Mobile resources, such …

WebJul 7, 2024 · Root anatomical phenotypes influence soil resource acquisition by regulating the metabolic cost of soil exploration, exploitation of the rhizosphere, the penetration of hard soil domains, the axial and radial transport of water, and interactions with soil biota including mycorrhizal fungi, pathogens, insects, and the rhizosphere microbiome. 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.
