Constantly changing environments often negatively affect yield potential. Phytohormone-based biostimulants are known for their ability to control plant development and reduce the influences of negative environmental impacts facilitate more efficient usage resources. The aim this study was evaluate effect phytohormone-based on lettuce (Lactuca sativa L.) antioxidant photosynthetic responses biom...

Rhizobia promote the growth of plants either directly through N2 fixation, supply of nutrients, synthesis of phytohormones and solubilization of minerals, or indirectly as a biocontrol agent by inhibiting the growth of pathogens. The biocontrol effect of rhizobia is due to the secretion of secondary metabolites such as antibiotics and HCN. Siderophore production in iron stress conditions provid...

Reserach in Murray Grant’s laboratory focuses predominately on three key themes of the interaction between Pseudomonas syringae and Arabidopsis thaliana: (i) how bacterial type III effectors suppress basal defense and promote nutrition, (ii) establishment of systemic immunity, and (iii) the mechanisms underlying function of the RPM1 disease resistance protein. Central to this research is the ne...

Until recently, there were rare scientific reports on the biotechnological potential of non-pathogenic bacteria Acinetobacter genus. Although first about practically valuable properties these date back to 70s and 80s twentieth century concerned synthesis emulsan bioemulsifier. In last decade, interest in representatives genus as objects biotechnology has significantly increased. The review pres...

The paper presents results of the study impacts chronic radiation exposure on hormonal system Scots pine in Chernobyl exclusion zone. Pine needles taken from three experimental plots with a contrasting level radioactive contamination: Polesie State Radioecological Reserve, Kozeluzh’ye forestry and Khoiniki June 2021 were used study. Artificial stands planted 1982, few years before accident. Whe...

The chloroplast is a photosynthetic organelle in plant cells. The development and function of the chloroplast are regulated by plant hormones, particularly cytokinin as a positive regulator and brassinosteroid as a negative regulator. We would like to clarify the molecular mechanism of chloroplast development regulated by the two phytohormones, and attempts to clarify the mechanism using the ap...

Gall-inducing insects often contain high concentrations of phytohormones, such as auxin and cytokinin, which are suggested to be involved in gall induction, but no conclusive evidence has yet been obtained. There two possible approaches investigating the importance phytohormones induction: demonstrating either that phytohormone productivity can induce gall-inducing ability non-gall-inducing or ...
