Journal ArticleDOI
Hydraulic conductivity of rice roots
TL;DR: The data suggest that the low overall hydraulic conductivity of rice roots is caused by the existence of apoplastic barriers in the outer root parts (exodermis and sclerenchymatous (fibre) tissue) and by a strongly developed endodermi rather than by theexistence of aerenchyma.
Journal ArticleDOI
Water permeability and reflection coefficient of the outer part of young rice roots are differently affected by closure of water channels (aquaporins) or blockage of apoplastic pores
TL;DR: Comparing diffusional (PdOPR, measured with heavy water, HDO) and osmotic water permeability (PfOPR) or hydraulic conductivity (LpOPR), which suggested a predominantly apoplastic water transport, suggested that, unlike water, rice roots efficiently retain oxygen within the aerenchyma and this ability strongly increases as roots/OPR develop.
Journal ArticleDOI
Control of water uptake by rice ( Oryza sativa L.): role of the outer part of the root
TL;DR: In this paper, a pressure-perfusion technique was used to measure hydraulic and osmotic properties of the outer part of roots (OPR) of 30-day-old rice plants.
Journal ArticleDOI
Blockage of apoplastic bypass-flow of water in rice roots by insoluble salt precipitates analogous to a Pfeffer cell
TL;DR: In this article, precipitates of insoluble inorganic salts were used to clog apoplastic pores in cell walls of the outer part of rice roots (OPR) in two rice cultivars (lowland cv IR64 and upland cv Azucena).
Journal ArticleDOI
QTLs affecting morph-physiological traits related to drought tolerance detected in overlapping introgression lines of rice (Oryza sativa L.)

TL;DR: The results indicate that improving drought tolerant (DT) of rice by selecting any single secondary traits is not expected to be effective and the identified QTLs for GY and related morph-physiological traits should be carefully confirmed before to be used for improving DT in rice by MAS.
