The plant immune system: From discovery to deployment

Cell, Journal Year: 2024, Volume and Issue: 187(9), P. 2095 - 2116

Published: April 1, 2024

Plant diseases cause famines, drive human migration, and present challenges to agricultural sustainability as pathogen ranges shift under climate change. breeders discovered Mendelian genetic loci conferring disease resistance specific isolates over 100 years ago. Subsequent breeding for underpins modern agriculture and, along with the emergence focus on model plants genetics genomics research, has provided rich resources molecular biological exploration last 50 years. These studies led identification of extracellular intracellular receptors that convert recognition microbe-encoded patterns or pathogen-delivered virulence effectors into defense activation. receptor systems, downstream responses, define plant immune systems have evolved since migration land ∼500 million Our current understanding provides platform development rational enhancement control many continue plague crop production.

The Role of Heat Shock Protein (Hsp) Chaperones in Environmental Stress Adaptation and Virulence of Plant Pathogenic Bacteria

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(2), P. 528 - 528

Published: Jan. 9, 2025

Plant pathogenic bacteria are responsible for a substantial number of plant diseases worldwide, resulting in significant economic losses. Bacteria exposed to numerous stress factors during their epiphytic life and within the host. Their ability survive host cause symptomatic infections depends on capacity overcome stressors. have evolved range defensive adaptive mechanisms thrive under varying environmental conditions. One such mechanism involves induction chaperone proteins that belong heat shock protein (Hsp) family. Together with proteases, these integral components quality control system (PQCS), which is essential maintaining cellular proteostasis. However, knowledge action considerably less extensive than human animal pathogens. This study discusses modulation Hsp levels by phytopathogenic response conditions, including elevated temperature, oxidative stress, changes pH or osmolarity environment, variable conditions infection. All influence bacterial virulence. Finally, secretion GroEL DnaK outside cell considered potentially important virulence trait.

Secrete or perish: The role of secretion systems in Xanthomonas biology

Computational and Structural Biotechnology Journal, Journal Year: 2020, Volume and Issue: 19, P. 279 - 302

Published: Dec. 25, 2020

Bacteria of the Xanthomonas genus are mainly phytopathogens a large variety crops economic importance worldwide. spp. rely on an arsenal protein effectors, toxins and adhesins to adapt environment, compete with other microorganisms colonize plant hosts, often causing disease. These effectors delivered their targets by action bacterial secretion systems, dedicated multiprotein complexes that translocate proteins extracellular environment or directly into eukaryotic prokaryotic cells. Type I type VI systems have been identified in genomes. Recent studies unravelled diverse roles played distinct types adaptation virulence xanthomonads, unveiling new aspects biology. In addition, genome sequence information from wide range species pathovars become available recently, uncovering heterogeneous distribution families within genus. this review, we describe architecture mode functions associated these important nanoweapons
