Stripe rust of wheat, caused by Puccinia striiformis f. sp. tritici, continues to cause severe damage worldwide. Durable resistance is necessary for sustainable control of the disease. High-temperature adult-plant (HTAP) resistance, which expresses when the weather becomes warm and plants grow older, has been demonstrated to be durable. We conducted numerous studies to understand the molecular ...
Vast collections of barley germplasm have been established and conserved in various global gene banks. These hold tremendous genetic diversity for resistance genes to Puccinia hordei, a causal agent leaf rust. This study was undertaken discover, characterize postulate the known Rph (resistance hordei) identify novel sources ASR (all-stage resistance) APR (adult plant P. hordei. A core set 315 l...
The treatment of gastrointestinal nematode infections in the 21st century is largely through use modern synthetic anthelmintics. However, there over growing drug resistance to anthelmintics goats and sheep. This present study was carried out determine vitro anthelmintic activitities Parkia biglobosa using Larval motility inhibition assay (LMIA) Adult (AMIA). stem root barks P. were extracted wh...
BACKGROUND Diaphorina citri populations in Florida are developing resistance to commonly used neurotoxic insecticides. Alternatives to neurotoxins, such as insect growth regulators, are needed to control this season-long subtropical pest to prevent or delay development of insecticide resistance. In the present investigation, two insect growth regulators (IGRs), buprofezin and diflubenzuron, wer...
We measured dieback and mortality in a chaparral shrub community at a chaparral/desert ecotone following four years of below-average rainfall. Ecotones are important systems in which to examine plant and community responses to extreme and prolonged drought conditions and the potential impact of global change on plant distributions and community composition. Following a particularly severe droug...
Recent research indicates that many ecosystems, including intertidal marshes, follow the alternative stable states theory. This theory implies that thresholds of environmental factors can mark a limit between two opposing stable ecosystem states, e.g. vegetated marshes and bare mudflats. While elevation relative to mean sea level is considered as the overall threshold condition for colonization...
Sheath blight is one of the most devastating wheat diseases worldwide. Breeding resistant cultivars is the most powerful strategy to defeat the disease. Plant resistance on "disease escape" works through modulation of morphological traits and shows sustainable resistance to disease. Plant architectural traits have been reported to play a significant role in disease response. Therefore, explorin...
