topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine csr2, csr4 and csr2xcsr4 crossbreed races of the silkworm, bombyx mori l. the results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoon...

Plant pathogenic organisms are known to affect plants by secreting enzymes, toxic compounds and phytohormones (IAA, KIN, GA, Zeatin and ABA). In the present study, bacteria were isolated from infected Prunus salicina. It was identified by biochemical tests and rDNA sequencing. It was studied for production of zeatin, a phytohormone known to influence plant growth and development. Conditions for...

Soil bacteria belonging to the genus Azotobacter, Pantoea and some unidentified soil isolates were tested in vitro for phytohormone production under laboratory and soil conditions. The German wheat variety Munk was inoculated by several soil bacteria with exogenously applied hormones (IAA, 2,4-D) and a flavonoid (naringenin) with a half of the amount of recommended doses of fertilizers under gr...

The constant struggle between plants and microbes has driven the evolution of multiple defense strategies in the host as well as offense strategies in the pathogen. To defend themselves from pathogen attack, plants often rely on elaborate signaling networks regulated by phytohormones. In turn, pathogens have adopted innovative strategies to manipulate phytohormoneregulated defenses. Tactics fre...

Plants, as sessile organisms, must coordinate various physiological processes to adapt to ever-changing surrounding environments. Stomata, the epidermal pores facilitating gas and water exchange, play important roles in optimizing photosynthetic efficiency and adaptability. Stomatal development is under the control of an intrinsic program mediated by a secretory peptide gene family--namely, EPI...

The aim of the current study was to isolate endophytes from roots Rhazya stricta and assess their potential improve growth drought-stressed sunflower seedlings. role isolated endophytic fungus initially screened by using two rice varieties (mutant cultivar Waito-C: Gibberellins deficient; Dongji byeo: Gibberellins-producing normal cultivar). A significant (p < 0.05) increase in various attri...
