Abstract
Pathogen attacks can cause significant damage to plants, posing a threaten to global food production. Plants have developed exquisite methods to rapidly store a key defensive hormone jasmonate (JA), which stimulates their entire evolutionary adaptive response to pathogen attack. However, understanding how plants initiate JA biosynthesis in response to pathogen attacks has remained elusive. In this review, we discuss the newly discovered JAV1-JAZ8-WRKY51 (JJW) complex, which plays a crucial role in regulating JA production to deter insect attacks. The JJW complex inhibits JA production in plants, maintaining a low baseline level of JA that promotes optimal plant development. However, when plants are attacked by insects, a rapid influx of calcium stimulates the JAV1 calcium-dependent protein phosphate, leading to the breakdown of the JJW complex and the activation of JA production. This surge in JA levels, initiates plant defense mechanisms against the invading insects. These findings shed light on the intricate defense system that plants have evolved to combat diseases.

Abstract
Myelocytomatosis (MYC) transcription factors (TFs) belong to the basic helix-loop-helix (bHLH) family in plants and play a central role in governing a wide range of physiological processes. These processes encompass plant growth, development, adaptation to biotic and abiotic stresses, as well as secondary metabolism. In recent decades, significant strides have been made in comprehending the multifaceted regulatory functions of MYCs. This advancement has been achieved through the cloning of MYCs and the characterization of plants with MYC deficiencies or overexpression, employing comprehensive genome-wide 'omics' and protein-protein interaction technologies. MYCs act as pivotal components in integrating signals from various phytohormones' transcriptional regulators to orchestrate genome-wide transcriptional reprogramming. In this review, we have compiled current research on the role of MYCs as molecular switches that modulate signal transduction pathways mediated by phytohormones and phytochromes. This comprehensive overview allows us to address lingering questions regarding the interplay of signals in response to environmental cues and developmental shift. It also sheds light on the potential implications for enhancing plant resistance to diverse biotic and abiotic stresses through genetic improvements achieved by plant breeding and synthetic biology efforts.

[PMID: 37879220 DOI: 10.1016/j.jplph.2023.154119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 09/28/2023] [Accepted: 10/16/2023] [Indexed: 10/27/2023]
Abstract
The appropriate timing of organ abscission determines plant growth, development, reproductive success, and yield in relation to crop species. Among these, yellow lupine is an example of a crop species that loses many fully developed flowers, which limits the formation of pods with high-protein seeds and affects its economic value. Lupine flower abscission, similarly to the separation of other organs, depends on a complex regulatory network functioning in the cells of the abscission zone (AZ). In the present study, genetic, biochemical, and cellular methods were used to highlight the complexity of the interactions among strong hormonal stimulators of abscission, including abscisic acid (ABA), ethylene, and jasmonates (JAs) precisely in the AZ cells, with all results supporting that the JA-related pathway has an important role in the phytohormonal cross-talk leading to flower abscission in yellow lupine. Based on obtained results, we conclude that ABA and ET have positive influence on JAs biosynthesis and signaling pathway in time-dependent manner. Both phytohormones changes lipoxygenase (LOX) gene expression, affects LOX protein abundance, and JA accumulation in AZ cells. We have also shown that the signaling pathway of JA is highly sensitive to ABA and ET, given the accumulation of COI1 receptor and MYC2 transcription factor in response to these phytohormones. The results presented provide novel information about the JAs-dependent separation of organs and provide insight and details about the phytohormone-related mechanisms of lupine flower abscission.

Abstract
JAZ proteins are involved in the regulation of the jasmonate signaling pathway, which is responsible for various physiological processes, such as defense response, adaptation to abiotic stress, growth, and development in Arabidopsis. The conserved domains of JAZ proteins can serve as binding sites for a broad array of regulatory proteins and the diversity of these protein-protein pairings result in a variety of functional outcomes. Plant growth and defense are two physiological processes that can conflict with each other, resulting in undesirable plant trade-offs. Recent observations have revealed a distinguishing feature of JAZ4; it acts as negative regulator of both plant immunity and growth and development. We suggest that these complex biological processes can be decoupled at the JAZ4 regulatory node, due to prominent expression of JAZ4 in specific tissues and organs. This spatial separation of actions could explain the increased disease resistance and size of the plant root and shoot in the absence of JAZ4. At the tissue level, JAZ4 could play a role in crosstalk between hormones such as ethylene and auxin to control organ differentiation. Deciphering biding of JAZ4 to specific regulators in different tissues and the downstream responses is key to unraveling molecular mechanisms toward developing new crop improvement strategies.

JOURNAL OF PLANT PHYSIOLOGY 2022; 273:153697. [PMID: 35487008 DOI: 10.1016/j.jplph.2022.153697] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/26/2021] [Revised: 04/11/2022] [Accepted: 04/11/2022] [Indexed: 06/14/2023]
Abstract
Alternaria blotch disease, caused by Alternaria alternata apple pathotype (AAAP), is one of the most prevalent diseases in apple production. To identify AAAP resistance-related genes and provide a theoretical basis for Alternaria blotch disease resistance breeding, we used two apple cultivars, 'Jonathan', a variety resistant to AAAP infection, and 'Starking Delicious', a variety susceptible to AAAP infection, as materials to perform transcriptome sequencing of apple leaves 72 h after AAAP infection. A Venn diagram showed that a total of 5229 DEGs of 'Jonathan' and 4326 DEGs of 'Starking Delicious' were identified. GO analysis showed that these DEGs were clustered into 25 GO terms, primarily "metabolic process" and "catalytic activity." Functional classification analyses of the DEGs indicated that "MAPK signaling pathway-plant pathway" is the most significant metabolic pathway among the top 15 KEGG pathways, followed by the "plant hormone signal transduction" pathway. There are more DEGs in 'Jonathan' that are significantly classified GO terms and KEGG pathways than in 'Starking Delicious'. Specifically, 13 DEGs were identified as involved in the GA-GID1-DELLA module, and the expression of MdGRAS53, a homologous gene of DELLA, was significantly upregulated in 'Jonathan' compared with 'Starking Delicious'. Phenotype analysis revealed that exogenous hormone GA3 suppressed apple resistance to AAAP infection and reduced the expression of MdGRAS53. The opposite result was observed for exogenous spraying of paclobutrazol (PAC), an inhibitor of gibberellin synthesis. Overexpression of MdGRAS53 in apple leaves by transient transformation decreased lesion area and the number of spores in leaves infected with AAAP, while silencing MdGRAS53 showed the opposite result. Meanwhile, SA/JA signaling pathway-related genes were upregulated significantly in MdGRAS53-overexpressed leaves and downregulated significantly in MdGRAS53-silenced leaves. The findings suggest that the GA-GID1-DELLA module is involved in apple resistance to AAAP, and MdGRAS53, a DELLA homologous gene, may play a positive role in this resistance by modulating cooperative JA- and SA-dependent pathways.

PLANTS (BASEL, SWITZERLAND) 2022; 11:plants11040527. [PMID: 35214860 PMCID: PMC8877524 DOI: 10.3390/plants11040527] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 02/10/2022] [Accepted: 02/13/2022] [Indexed: 05/31/2023]
Abstract
Lipid membranes, as primary places of the perception of environmental stimuli, are a source of various oxygenated polyunsaturated fatty acids-oxylipins-functioning as modulators of many signal transduction pathways, e.g., phytohormonal. Among exogenous factors acting on plant cells, special attention is given to drought, especially in highly sensitive crop species, such as yellow lupine. Here, we used this species to analyze the contribution of lipid-related enzymes and lipid-derived plant hormones in drought-evoked events taking place in a specialized group of cells-the flower abscission zone (AZ)-which is responsible for organ detachment from the plant body. We revealed that water deficits in the soil causes lipid peroxidation in these cells and the upregulation of phospholipase D, lipoxygenase, and, concomitantly, jasmonic acid (JA) strongly accumulates in AZ tissue. Furthermore, we followed key steps in JA conjugation and signaling under stressful conditions by monitoring the level and tissue localization of enzyme providing JA derivatives (JASMONATE RESISTANT1) and the JA receptor (CORONATINE INSENSITIVE1). Collectively, drought-triggered AZ activation during the process of flower abscission is closely associated with the lipid modifications, leading to the formation of JA, its conjugation, and induction of signaling pathways.
