Do root hairs of barley and maize roots reinforce soil under shear stress?

Rhizosphere priming of barley with and without root hairs

The influence of plant roots and the associated rhizosphere activities on decomposition of soil organic matter (SOM), the rhizosphere priming effect, has emerged as a crucial mechanism regulating global carbon (C) and nitrogen (N) cycles. However, the role of root morphology in controlling the rhizosphere priming effect remains largely unknown. To investigate the link between root hairs, a crit...

Internal water balance of barley under soil moisture stress.

Leaf water potential, leaf relative water content, and relative transpiration of barley were determined daily under greenhouse conditions at 3 growth stages: tillering to boot, boot to heading, and heading to maturity. The leaf moisture characteristic curve (relative water content versus leaf water potential) was the same for leaves of the same age growing in the same environment for the first ...

Phosphorylation by Barley Root Mitochondria & Phosphate Absorption by Barley Roots.

The absorption by roots of ions in general, and phosphate absorption in particular, can occur against concentration gradients so great as to require free energy changes of the order of 8,000 calories per nmole. This implies coupling in the absorption process with reactions Jeroceecling wdith considerable free energy decrease. Few reacticius in plants other than those for production or destructi...

The Study of SOS Genes Expression in Mutant Barley Root under Salt Stress

Soil salinity is one of the most critical factors reducing crop yield. SOS signaling is one of the significant pathways that regulate ion homeostasis and it has the important role in mechanism of plant resistance to environmental stresses such as salt stress. Roots are the first organ of plants exposed to salt, so the role of genes involved in this pathway and their relation to salt tolerance w...
