Abstract:
Despite extensive research on sphingolipid metabolism in Arabidopsis thaliana, the involvement of this pathway in major crop species, including rapeseed, rice, maize, soybean, and cotton, remains poorly understood. This knowledge gap presents an opportunity to explore sphingolipid biosynthesis in these crops, with the potential to identify novel, crop-specific sphingolipids that regulate yield-related traits. Sphingolipids are key regulators of plant responses to abiotic stresses such as drought, salinity, and freezing, as well as biotic interactions, including disease resistance and plant-microbe communication. Given their critical roles in plant physiology, sphingolipid pathways represent promising targets for enhancing stress resilience and optimizing crop productivity, offering new strategies for sustainable agriculture to meet the challenges of a growing global population. We have also listed the predicted homologs/orthologues of the pathway genes in rapeseed, soybean, rice, maize, and cotton based on amino acid sequence alignment score with Arabidopsis. This review provides an outline for projecting sphingolipid metabolic pathways across major crops, and enabling the prioritization of target genes to enhance key agronomic traits.
