Mucilage, a gelatinous substance comprising mostly polysaccharides, is exuded by maize nodal and underground root tips. Although mucilage provides several benefits for rhizosphere functions, studies on the variation in amounts its polysaccharide composition between genotypes are still lacking. In this study, eight ( Zea mays L.) from different globally distributed agroecological zones were grown under identical abiotic conditions randomized field experiment. Mucilage exudation amount,...
Stomatal regulation allows plants to promptly respond water stress. However, our understanding of the impact above and belowground hydraulic traits on stomatal remains incomplete. The objective this study was investigate how key plant transpiration maize during soil drying. We hypothesize that response drying is related a loss in conductivity at root-soil interface, which turn depends traits.We 48 contrasting (Zea mays) genotypes drying, utilizing novel phenotyping facility. In context, we...
High atmospheric vapor pressure deficits lead to high transpiration demands which can induce plant water stress because of large dissipation potential within tissues, but also the demand exceeds possible root uptake rate from soil. The latter point might be particularly critical in coarse textured soils display poor soil-root contact and an unsaturated hydraulic conductivity curve steeply decreasing with matric potential. Root hairs increase by increasing root-soil effective radius. Thus, we...
Abstract With ongoing climate change and the increase in extreme weather events, especially droughts, challenge of maintaining food security is becoming ever greater. Locally adapted landraces crops represent a valuable source adaptation to stressful environments. In light future droughts—both by altered soil water supply increasing atmospheric demand (vapor pressure deficit [VPD])—plants need improve their efficiency. To do so, plants can enhance access improving rhizosphere hydraulic...
<p>Limited water supply is one of the largest impediments to food production worldwide in light climate change and increasing demand. Stomatal regulation allows plants promptly react stress regulate use. Although coordination between stomatal closure aboveground hydraulics has extensively been studied, our understanding impact belowground on remains, as yet, incomplete. The overall objective this study was investigate hydraulic conductivity affected by differences expressions...
