Abstract Drought is one of the major threats to food security. Among several mechanisms involved in plant stress tolerance, protein family—the metallothioneins (MTs)—shows great promise for enhancing drought resistance. Plant oat ( Avena sativa L.) have not yet been deeply analysed, and literature lacks a comprehensive study whole family MTs response drought. In this study, we showed that number nature cis -elements linked with promoters AsMTs1–3 differed depending on MT type. plants caused...

Somatic embryogenesis (SE) of Cyathea delgadii presents a model system for investigating the mechanisms associated with acquisition embryogenic competence by single epidermal cells stipe explants cultured on plant growth regulator-free medium. The present work reveals relationship between endogenous hormone and sugar content in process early SE C. delgadii. By comparing two types initial explants, i.e. incapable (non-etiolated) capable (etiolated) SE, it was established that etiolated...

Effective microspore embryogenesis in triticale is determined by a specific hormonal homeostasis: low value of IAA/cytokinins, IAA/ABA and cytokinins/ABA ratios as well proper endogenous/exogenous auxin balance, which favours androgenic structure formation green plant regeneration ability. The concentration growth regulators (PGRs): auxins (Auxs), cytokinins (CKs) abscisic acid (ABA) was measured anthers eight DH lines (× Triticosecale Wittm.), associated with (ME) responsiveness. analysis...

Abstract Polycyclic aromatic hydrocarbons (PAHs) are the products of incomplete combustion organic materials, which present in cigarette smoke, deep‐fried food, and natural crude oil. Since PAH‐metabolites form DNA adducts cause oxidative damage, we asked if these environmental carcinogens could affect transforming potential human Polyomavirus JC oncoprotein, T‐antigen (JCV T‐antigen). We extracted DMSO soluble PAHs from Deepwater Horizon oil spill Gulf Mexico (oil‐PAHs), detected several...
