PRG's Effect on Root Growth
Need fast-acting control of surfacefeeding and soil insects? Dylox insecticide works immediately after irrigation or rainfall to control insects such as white grubs, mole crickets, sod webworms and cutworms. The fastworking product penetrates thatch up to a half-inch thick when watered properly, providing grub control within 24 hours. Under normal conditions, Dylox controls the pest and then de...
متن کاملA role for the root cap in root branching revealed by the non-auxin probe naxillin.
The acquisition of water and nutrients by plant roots is a fundamental aspect of agriculture and strongly depends on root architecture. Root branching and expansion of the root system is achieved through the development of lateral roots and is to a large extent controlled by the plant hormone auxin. However, the pleiotropic effects of auxin or auxin-like molecules on root systems complicate the...
متن کاملRoot Polytopes and Growth Series of Root Lattices
The convex hull of the roots of a classical root lattice is called a root polytope. We determine explicit unimodular triangulations of the boundaries of the root polytopes associated to the root lattices An, Cn and Dn, and compute their f -and h-vectors. This leads us to recover formulae for the growth series of these root lattices, which were first conjectured by Conway–Mallows–Sloane and Baak...
متن کاملHvEXPB7, a novel β-expansin gene revealed by the root hair transcriptome of Tibetan wild barley, improves root hair growth under drought stress.
Tibetan wild barley is a treasure trove of useful genes for crop improvement including abiotic stress tolerance, like drought. Root hair of single-celled structures plays an important role in water and nutrition uptake. Polyethylene-glycol-induced drought stress hydroponic/petri-dish experiments were performed, where root hair morphology and transcriptional characteristics of two contrasting Ti...
