Abstract
Poplar (Populus) is a genus of woody plants of great economic value. Due to the growing economic importance of poplar, there is a need to ensure its stable growth by increasing its resistance to pathogens. Genetic engineering can create organisms with improved traits faster than traditional methods, and with the development of CRISPR/Cas-based genome editing systems, scientists have a new highly effective tool for creating valuable genotypes. In this review, we summarize the latest research data on poplar diseases, the biology of their pathogens and how these plants resist pathogens. In the final section, we propose to plant male or mixed poplar populations; consider the genes of the MLO group, transcription factors of the WRKY and MYB families and defensive proteins BbChit1, LJAMP2, MsrA2 and PtDef as the most promising targets for genetic engineering; and also pay attention to the possibility of microbiome engineering.

Culturable Bacterial Endophytes of Wild White Poplar ( Populus alba L.) Roots: A First Insight into Their Plant Growth-Stimulating and Bioaugmentation Potential. BIOLOGY 2023; 12:1519. [PMID: 38132345 PMCID: PMC10740426 DOI: 10.3390/biology12121519] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 12/06/2023] [Accepted: 12/09/2023] [Indexed: 12/23/2023]
Abstract
The white poplar (Populus alba L.) has good potential for a green economy and phytoremediation. Bioaugmentation using endophytic bacteria can be considered as a safe strategy to increase poplar productivity and its resistance to toxic urban conditions. The aim of our work was to find the most promising strains of bacterial endophytes to enhance the growth of white poplar in unfavorable environmental conditions. To this end, for the first time, we performed whole-genome sequencing of 14 bacterial strains isolated from the tissues of the roots of white poplar in different geographical locations. We then performed a bioinformatics search to identify genes that may be useful for poplar growth and resistance to environmental pollutants and pathogens. Almost all endophytic bacteria obtained from white poplar roots are new strains of known species belonging to the genera Bacillus, Corynebacterium, Kocuria, Micrococcus, Peribacillus, Pseudomonas, and Staphylococcus. The genomes of the strains contain genes involved in the enhanced metabolism of nitrogen, phosphorus, and metals, the synthesis of valuable secondary metabolites, and the detoxification of heavy metals and organic pollutants. All the strains are able to grow on media without nitrogen sources, which indicates their ability to fix atmospheric nitrogen. It is concluded that the strains belonging to the genus Pseudomonas and bacteria of the species Kocuria rosea have the best poplar growth-stimulating and bioaugmentation potential, and the roots of white poplar are a valuable source for isolation of endophytic bacteria for possible application in ecobiotechnology.

Abstract
Tree planting and natural regeneration contribute to the ongoing effort to restore Earth's forests. Our review addresses how the plant microbiome can enhance the survival of planted and naturally regenerating seedlings and serve in long-term forest carbon capture and the conservation of biodiversity. We focus on fungal leaf endophytes, ubiquitous defensive symbionts that protect against pathogens. We first show that fungal and oomycetous pathogen richness varies greatly for tree species native to the United States (n = 0-876 known pathogens per US tree species), with nearly half of tree species either without pathogens in these major groups or with unknown pathogens. Endophytes are insurance against the poorly known and changing threat of tree pathogens. Next, we review studies of plant phyllosphere feedback, but knowledge gaps prevent us from evaluating whether adding conspecific leaf litter to planted seedlings promotes defensive symbiosis, analogous to adding soil to promote positive feedback. Finally, we discuss research priorities for integrating the plant microbiome into efforts to expand Earth's forests.

J Appl Microbiol 2021; 132:495-508. [PMID: 34170610 DOI: 10.1111/jam.15190] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Revised: 05/19/2021] [Accepted: 06/13/2021] [Indexed: 01/02/2023]
Abstract
AIM To investigate the role of the leading saffron endophyte Burkholderia gladioli strain E39CS3 (BG-E39) in the inhibition of corm-rot and induced systemic resistance (ISR) in the host against the saffron specific pathogen, Fusarium oxysporum. METHODS AND RESULTS We studied the interaction between BG-E39 and the corm-rot pathogen F. oxysporum in vitro and in vivo. BG-E39 strongly inhibited both the F. oxysporum strains and other saffron-specific and non-specific pathogens used in this study. Confrontation and microscopic analyses revealed that the endophyte possessed fungicidal activity against the pathogens and effectively induced cell death in the mycelia. The endophyte produced chitinases as well as β-1,3-glucanase that may be involved in the pathogen cell wall degradation. BG-E39 did not cause corm-rot in Crocus sativus and the closely related plant, Gladiolus, thus establishing that it is non-pathogenic to these plants. The endophyte reduced corm-rot through antibiosis and enhanced the endogenous jasmonic acid (JA) levels and expression of JA-regulated and other plant defence genes. CONCLUSIONS The bacterial endophyte BG-E39 provides resistance to the host plant against F. oxysporum corm-rot in nature. SIGNIFICANCE AND IMPACT OF THE STUDY The current study discovers the role of the saffron endophyte BG-E39 in providing resistance to the host against corm-rot. Therefore, this endophyte is a potential candidate for developing a microbial formulation for the biocontrol of the most common disease of C. sativus.
