Selecting High Zinc-efficient and Assessment of Zinc Stress Tolerance of the Wheat Durum Genotypes
At percent, Zn stress tolerance using novel genetic resources is an important mitigation strategy for plant breeding. In this study, thirty-five durum wheat genotypes with different growth habits were evaluated under normal (non-stress) and Zn deficient stress during the 2014-15 cropping season. A total of ten Zn stress tolerance indices including stress tolerance index (STI), relative zinc-def...
متن کاملMycorrhizal influences on big bluestem rhizome regrowth and clipping tolerance
Mycorrbizal symbiosis is critical to growth of many warmseason prairie grass seedlings, but its effect on regrowth of rbizomes has not been determined. As forage species, the effect of grazing on the symbiosis is also important. when the impact of mycorrbizae on regrowth of Andropogon germ&i Vit. rhizomes was assessed, A. germ& rhizomes collected from the field and grown with mycorrbizal inocul...
متن کاملTolerance of an Expanding Subarctic Shrub, Betula glandulosa, to Simulated Caribou Browsing
Densification of the shrub layer has been reported in many subarctic regions, raising questions about the implication for large herbivores and their resources. Shrubs can tolerate browsing and their level of tolerance could be affected by browsing and soils productivity, eventually modifying resource availability for the caribou. Our objective was to assess the compensatory growth potential of ...
متن کاملNicotianamine secretion for zinc excess tolerance.
Plants acquire micronutrients such as iron (Fe), zinc (Zn), manganese, or copper from soil. These micronutrients are often not readily available and they need to be mobilized to the proper free ionic form in order to be taken up by plant roots. Perhaps the only exception to this is the uptake of Fe by grasses, which have evolved a so-called strategy II uptake mechanism that involves the secreti...
متن کاملAn Ethylene-responsive Factor BpERF11 Negatively Modulates Salt and Osmotic Tolerance in Betula platyphylla
Ethylene responsive factors (ERFs) play important roles in the abiotic stress; however, only a few ERF genes from woody plants have been functionally characterized. In the present study, an ERF gene from Betula platyphylla (birch), BpERF11, was functionally characterized in response to abiotic stress. BpERF11 is a nuclear protein, which could specifically bind to GCC boxes and DRE motifs. BpERF...
