Sammanfattning
Global agricultural production is currently limited by ongoing climate change.Approximately 90% of crop species and numerous wild plants are dependent onpollinators for reproduction. The global threat to pollinators posed by climatechange has grown considerably, as higher temperatures, shifting rainfall patterns,and more frequent extreme weather events disrupt the fragile relationshipsbetween plants and their pollinators. The decline in pollinators is also linked toshifts in land use, the widespread adoption of monocropping, and heavy relianceon agrochemicals. Therefore, the protection of pollinators and the preservation ofagrobiodiversity are essential to uphold global food systems. Here, we synthesizethe adverse impact of climate change on plant-pollinator interactions;throughput assay for phenotyping floral traits; assessing variability andmolecular basis of floral display (flower size, shape, color, attractants etc.) andreward (nectar volume and composition, pollen, and fragrance in case ofornamental plants) traits; crop domestication and inbreeding, ploidy and matingsystems differences impacting plant-pollinator interactions; volatiles andmetabolites mediating plant-pollinator relationships; trade-offs involvingreproductive and pollinator traits; and finally, progress in developing pollinator-friendly crop cultivars through conventional plant breeding and biotechnologicalinterventions. Pollinator-assisted phenotyping and selection platform (DARkWIN)combined with other high-throughput phenotyping assays, has the potential tosimultaneously quantify multiple interactions impacting pollinators’ visitation andforaging behaviors, and generate data on other parameters like stress tolerance,yield, and nutrition in the target populations. Assessing and exploiting functionaldiversity for plant-pollinator interactions, combined with the use of functionallycharacterized genes and associated markers for floral display (AT2G31010,AT4G17080, CmGEG, CmCYC2c, CmJAZ1-like-CmBPE2, Cyc2CL-1, Cyc2CL-2)and reward (SWEET9, BrCWINV4A, EOBI, EOBII) traits, can be deployed inbreeding programs to develop pollinator-friendly crop cultivars. Numerouscandidate genes, reported herein, must be functionally validated before beingdeployed in crop breeding programs.
