Plant Invasion Research in Russia: Basic Projects and Scientific Fields.

ABSTRACT: This paper represents a review of comprehensive research into invasion biology done by Russian scholars for four decades. Invasion biology is a relatively new field of research focused on the study of alien plants, their behavior in new habitats and risks they pose to indigenous species. It is shown that over 40 years, single finds of alien plant species have transformed into a check-list of invasive species in Russia. The most significant invasion pathways were identified, and the rate of microevolutional changes in plant species in their secondary distribution range was determined. Since the most active alien species disperse without regard to national borders, international cooperation is crucial in joint studies of invasive species.

Project description:Cadmium (Cd) is a highly toxic and carcinogenic pollutant that poses a threat to human and animal health by affecting several major organ systems. Urbanization and human activities have led to significant increases in Cd concentration in the environment, including in agroecosystems. To protect against the harmful effects of Cd, efforts are being made to promote safe crop production and to clean up Cd-contaminated agricultural lands and water, reducing Cd exposure through the consumption of contaminated agricultural products. There is a need for management strategies that can improve plant Cd tolerance and reduce Cd accumulation in crop plant tissues, all of which involve understanding the impacts of Cd on plant physiology and metabolism. Grafting, a longstanding plant propagation technique, has been shown to be a useful approach for studying the effects of Cd on plants, including insights into the signaling between organs and organ-specific modulation of plant performance under this form of environmental stress. In this review, we aim to highlight the current state of knowledge on the use of grafting to gain insights into Cd-induced effects as well as its potential applicability in safe crop production and phytoremediation. In particular, we emphasize the utility of heterograft systems for assessment of Cd accumulation, biochemical and molecular responses, and tolerance in crop and other plant species under Cd exposure, as well as potential intergenerational effects. We outline our perspectives and future directions for research in this area and the potential practical applicability of plant grafting, with attention to the most obvious gaps in knowledge. We aim at inspiring researchers to explore the potential of grafting for modulating Cd tolerance and accumulation and for understanding the mechanisms of Cd-induced responses in plants for both agricultural safety and phytoremediation purposes. Finally, it is important to bear in mind that although we have address Cd in this review, the idea can be applied to the large majority of abiotic and biotic stressors.
