Salicylic Acid in Root Growth and Development
In plants, salicylic acid (SA) is a hormone that mediates a plant’s defense against pathogens. SA also takes an active role in a plant’s response to various abiotic stresses, including chilling,
Action of Salicylic Acid on Plant Growth
The phytohormone salicylic acid (SA) not only is a well-known signal molecule mediating plant immunity, but also is involved in plant growth regulation. However, while its role in plant immunity has
Pathogens pulling the strings: Effectors manipulating salicylic acid and phenylpropanoid biosynthesis in plants
TLDR
This review will focus on the different strategies pathogens have developed to affect the levels of SA and phenylpropanoids to increase plant susceptibility.
Salicylic Acid Signalling Under Stress Conditions in Plants
TLDR
In the present chapter, certain stress-related defence mechanisms, which are also affected by SA, will be discussed.
Salicylic Acid and N-Hydroxypipecolic Acid at the Fulcrum of the Plant Immunity-Growth Equilibrium
TLDR
This article provides an overview of how SA and NHP regulate local and systemic immune responses in plants and highlights how these two signals are mutually potentiated and are convergent on multiple aspects—from biosynthesis to homeostasis, and from signaling to gene expression and phenotypic responses.
Salicylic acid: A key regulator of redox signalling and plant immunity.
Salicylic Acid and Nitric Oxide: Insight Into the Transcriptional Regulation of Their Metabolism and Regulatory Functions in Plants
TLDR
Transcriptional regulation of SA and NO signaling are crucial for fine-tuning important cellular and metabolic functions, thus making plant defense impervious against many pathogens, and playing an indispensable role in stimulating plant-microbe interaction to modulate crucial plant functions.
Degradation of salicylic acid to catechol in Solanaceae by SA 1-hydroxylase.
TLDR
Phylogenetic analysis and functional characterization of SA1H homologs from other species indicated that this type of FAD/NADH-dependent SA 1-hydroxylases evolved recently within the Solanaceae family.
Multiple plant hormone catabolism activities: an adaptation to a plant-associated lifestyle by Achromobacter spp.
TLDR
Genomic analysis demonstrated the presence of IAA, PAA and BA degradation gene clusters, as well as the nag gene cluster (SA catabolism) and the acdS gene (ACC deaminase), in the genomes of strains SOLR10 and AB2.

Salicylic acid and its function in plant immunity.
TLDR
Characterization of a number of genes functioning in SA biosynthesis, conjugation, accumulation, signaling, and crosstalk with other hormones has sketched the finely tuned immune response network, holding the potential for isolating additional mutants related to SA-mediated defense signaling.
Spatial and temporal regulation of biosynthesis of the plant immune signal salicylic acid
TLDR
This study identified two transcription factors, NTM1-LIKE 9 (NTL9) and CCA1 HIKING EXPEDITION (CHE), as activators of ICS1 during specific immune responses, which fills a gap in the signal transduction pathway between pathogen recognition and SA production.
Isochorismate-derived biosynthesis of the plant stress hormone salicylic acid
TLDR
It is shown that in Arabidopsis, the pathway downstream of isochorismate requires only two additional proteins; the minimal requirement of three compartmentalized proteins controlling unidirectional forward flux may protect the pathway against evolutionary forces and pathogen perturbations.
Cooperative functioning between phenylalanine ammonia lyase and isochorismate synthase activities contributes to salicylic acid biosynthesis in soybean.
TLDR
Results show that PAL- and ICS-catalyzed reactions function cooperatively in soybean defense and highlight the importance of PAL in pathogen-induced SA biosynthesis.
Isochorismate synthase is required to synthesize salicylic acid for plant defence
TLDR
By cloning and characterizing an Arabidopsis defence-related gene (SID2) defined by mutation, it is shown that SA is synthesized from chorismate by means of ICS, and that SA made by this pathway is required for LAR and SAR responses.
Hormone crosstalk in plant disease and defense: more than just jasmonate-salicylate antagonism.
TLDR
Recent advances are reported, updating current knowledge on classical defense hormones SA, JA, and ET, and the roles of auxin, abscisic acid (ABA), cytokinins (CKs), and brassinosteroids in molding plant-pathogen interactions are updated.
Salicylic acid beyond defence: its role in plant growth and development.
TLDR
The evidence that supports the role of SA during plant growth and development is reviewed by comparing experiments performed by exogenous application of SA with analysis of genotypes affected by SA levels and/or perception.
Multiple Targets of Salicylic Acid and Its Derivatives in Plants and Animals
TLDR
Two recently identified SABPs, high mobility group box protein and glyceraldehyde 3-phosphate dehydrogenase, are critical proteins that not only serve key structural or metabolic functions but also play prominent roles in disease responses in both kingdoms.
Salicylic Acid: A Double-Edged Sword for Programed Cell Death in Plants
TLDR
High levels of SA have been shown to negatively regulate plant cell death during effector-triggered immunity, suggesting that SA has dual functions in cell death control.
