Plants are exposed to increasingly severe drought events and roots play vital roles in maintaining plant survival, growth, reproduction. A large body of literature has investigated the adaptive responses root traits various plants water stress these studies have been reviewed certain groups species at a scale. Nevertheless, not synthesized multiple levels. This paper screened over 2000 literatures for typical including growth angle, depth, length, diameter, dry weight, root-to-shoot ratio, hair length density integrates their genetic morphological scales. The genes, quantitative trait loci (QTLs) hormones that involved regulation response were summarized. We then statistically analyzed discussed underlying mechanisms. Moreover, we highlighted 1-D 2-D (RLD) distribution soil profile. will provide framework an integrated understanding deficit scales such insights may basis selection breeding tolerant crop lines.

Phosphorus (P) and water are crucial for plant growth, but their availability is challenged by climate change, leading to reduced crop production global food security. In many agricultural soils, productivity confronted both P limitations. The diminished soil moisture decreases available due diffusion, inadequate diminishes tissue status through modifications in stomatal conductance a decrease root hydraulic conductance. display contrasting distributions the soil, with being concentrated topsoil subsoil. Plants adapt water- P-limited environments efficiently exploring localized resource hotspots of adaptation system. Thus, developing cultivars improved architecture accessing utilizing from arid P-deficient soils. To meet this goal, breeding towards multiple advantageous traits can lead better environments. This review discusses interplay highlights specific that enhance exploration exploitation optimal resource-rich strata while reducing metabolic costs. We propose ideotype models, including 'topsoil foraging', ʻsubsoil 'topsoil/subsoil foraging' maize (monocot) common bean (dicot).

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(12), С. 9879 - 9879

Phosphorus (P) is the second most important macronutrient for crop growth and a limiting factor in food production. Choosing right P fertilizer formulation production systems because not mobile soils, placing phosphate fertilizers major management decision. In addition, root microorganisms play an role helping phosphorus fertilization by regulating soil properties fertility through different pathways. Our study evaluated impact of two phosphorous formulations (polyphosphates orthophosphates) on physiological traits wheat related to yield (photosynthetic parameters, biomass, morphology) its associated microbiota. A greenhouse experiment was conducted using agricultural deficient (1.49%). Phenotyping technologies were used at tillering, stem elongation, heading, flowering, grain-filling stages. The evaluation revealed highly significant differences between treated untreated plants but fertilizers. High-throughput sequencing applied analyse rhizosphere rhizoplane microbiota tillering alpha- beta-diversity analyses bacterial fungal fertilized non-fertilized wheat, rhizosphere, rhizoplane, provides new information composition during stages (Z39 Z69) under polyphosphate orthophosphate fertilization. Hence, deeper understanding this interaction could provide better insights into managing microbial communities promote beneficial plant-microbiome interactions uptake.

Plant Physiological Analysis to Overcome Limitations to Plant Phenotyping

Plants, Год журнала: 2023, Номер 12(23), С. 4015 - 4015

Опубликована: Ноя. 29, 2023

Plant physiological status is the interaction between plant genome and prevailing growth conditions. Accurate characterization of physiology is, therefore, fundamental to effective phenotyping studies; particularly those focused on identifying traits associated with improved yield, lower input requirements, climate resilience. Here, we outline approaches used assess how these techniques direct empirical observations processes such as photosynthetic CO2 assimilation, stomatal conductance, photosystem II electron transport, or effectiveness protective energy dissipation mechanisms are unsuited high-throughput applications. Novel optical sensors, remote/proximal sensing (multi- hyperspectral reflectance, infrared thermography, sun-induced fluorescence), LiDAR, automated analyses below-ground development offer possibility infer growth. However, there limitations ‘indirect’ gauging physiology. These methodologies that appropriate for rapid high temporal screening a number crop varieties over wide spatial scale do still require ‘calibration’ ‘validation’ measurement status. The use deep-learning artificial intelligence may enable synthesis large multivariate datasets more accurately quantify characters rapidly in numbers replicate plants.

Abstract The unprecedented challenges to crop production driven by climate change drivers warrant the development of resilient varieties sustain yield. In present and future, climate, drought, salinity temperature stress will be major yield‐limiting factors. Roots are primary responders flooding assume a key position in developing plant resilience. Root architecture has emerged as promising focal point breeding efforts aimed at resource‐efficient crops. However, selection frequently prioritises shoot performance exclusively because evaluating root traits is more intricate process.
