“…Lipids (see Glossary), a ubiquitous class of biomolecules and major constituents of eukaryotic and prokaryotic cell membranes, are essential for a complete study of cell biology and functions. Lipids serve as structural components of plasma and intracellular membranes, provide energy and carbon storage, mediate cell signaling pathways, and regulate stress responses [1][2][3]. Because of their diverse roles, lipid homeostasis and lipid metabolism have systemic effects that can influence plant development and performance [4].…”

“…Apart from acting as chemical signals in rhizosphere signaling, lipids are also involved in diverse functions during pathogen attack or infection and mutualistic interactions with beneficial microorganisms. Specific lipids in the PM have particular functions, such as in host-specific pathogen recognition, signaling in the cells from the site of infection or interaction, and transfer of infection signals to distal organs of the plants during defense responses [2,31,59,60]. Signal-inducing compounds from microbes or elicitors are recognized by the plant's innate immune system, which results in the induction of defense responses [59] or invasion of host tissues [13].…”

“…Changes in the phospholipid composition of membranes could have direct functional effects on the protein machinery embedded in or associated with them which, in turn, may alter intra-and intercellular signaling (Champeyroux et al, 2020). In addition, there are many well established examples of lipids functioning directly as signaling molecules in plants (Wang and Chapman, 2013;Ruelland and Valentova, 2016). These examples include roles for lipids in responding to abiotic stresses such as chilling and freezing responses (Welti et al, 2002;Hou et al, 2016).…”

Phospholipid biosynthesis is a core metabolic pathway that affects all aspects of plant growth and development. One of the earliest step in this pathway is mediated by choline/ethanolamine kinases (CEKs), enzymes in the Kennedy pathway that catalyze the synthesis of the polar head groups found on the most abundant plant phospholipids. The Arabidopsis genome encodes four CEKs. CEK1-3 have been well characterized using viable mutants while CEK4 encodes an essential gene, making it difficult to characterize its effects on plant development and responses to the environment. We have isolated an EMS-induced allele of CEK4 called bumpy stem (bst). bst plants are viable, allowing the effects of decreased CEK4 function to be characterized throughout the Arabidopsis life cycle. bst mutants have a range of developmental defects including ectopic stem growths at the base of their flowers, reduced fertility, and short roots and stems. They are also sensitive to cold temperatures. Supplementation with choline, phosphocholine, ethanolamine, and phosphoethanolamine rescues bst root phenotypes, highlighting the flow of metabolites between the choline and ethanolamine branches of the Kennedy pathway. The identification of bst and characterization of its phenotypes defines new roles for CEK4 that go beyond its established biochemical function as an ethanolamine kinase.

“…1A). Lipids, which are constituents of primarily cell membranes, play a crucial role as "chemical language" in rhizosphere microbial colonization and interaction (Macabuhay et al 2022;Ruelland and Valentova 2016). Furthermore, we discovered that in both tomato and pepper, the diversity of the diseased rhizosphere metabolites was signi cantly lower compared with healthy rhizosphere (Fig.…”

Background and Aims The rhizosphere environment regulated by root secretory activity and rhizosphere microbial interactions plays an essential role in resisting soil-borne diseases, while the host species is an important factor that affects the composition of root exudates and rhizosphere microbiomes. However, few studies have been done on the characteristics of root exudates and bacterial communities in terms of composition, diversity, and functional potential when host plants of different species are subjected to the same disease. Methods In this study, we examined the rhizosphere soil bacteria and root exudates of both healthy and diseased tomatoes and peppers employing metabolomics and amplicon techniques. Results Our findings indicated that variations existed in both root exudates and the bacterial community among different host species and health states. The diversities of both rhizosphere metabolites and bacterial communities were significantly reduced in different diseased plants. Although pepper and tomato resisted the invasion of Ralstonia by recruiting different potentially beneficial bacteria, their rhizosphere bacterial communities had the same functional potential. In contrast with diseased rhizosphere soil, healthy rhizosphere soil had many more functional pathways associated with disease suppression and plant growth. Conclusions This study highlighted the crucial role of host plants in shaping the rhizosphere environment and revealed the variation characteristics of root exudes and rhizosphere bacteria of different host plants induced by the same disease.
