Beyond skin-deep: targeting the plant surface for crop improvement

Area of Science:

• Plant Biology
• Molecular Genetics
• Agricultural Science

Background:

• The above-ground plant surface, including the cuticle and epidermal cells, is crucial for plant survival and function.
• This interface regulates gas exchange, protects against environmental stresses (desiccation, pathogens, herbivores), and mediates interactions with pollinators and dispersers.
• In agriculture, plant surface characteristics significantly impact crop yield and post-harvest quality.

Conclusions:

• Molecular insights into plant surface development offer pathways for enhancing crop traits.
• Genetic manipulation of cuticle and epidermal development holds potential for improving crop yield, quality, and resilience.
• New breeding techniques can leverage this knowledge for targeted crop improvement strategies.
