Environmental Stressors Can Alter Aboveground Bud Protection Strategies in a Shrub Cerrado Species
Original language description
Disturbance-prone ecosystems, such as the world's savannas, are predominantly composed of plant species that developed several morphoanatomical adaptations that grant them high resilience to natural and anthropogenic disturbances. An essential adaptation is the protection of aboveground buds, which play a crucial role in the formation of new photosynthetic organs and enable colonization of these areas. Our study aims to assess whether the protection mechanisms of aboveground buds of Psidium grandifolium Mart. ex DC. are affected by environmental stressors in two distinct environments: a natural Cerrado area and a Cerrado area under regeneration after decades of use as a pine plantation. Aerial branches were collected from both environments and processed using standard methodologies for light, fluorescence, and scanning microscopy analyses. Our observations revealed the presence of hairy leaf primordia with phenolic compounds and secretory cavities covering the buds in both areas. Additionally, crystals, brachysclereids, and colleters were consistently found near the buds in all analyzed nodes. In the plants from the regenerating area, the buds increased hairiness and deposition of epicuticular waxes on both surfaces of expanded leaves as a response to the intense sunlight exposure. Our findings highlight that belowground resprouting species also invest in aboveground bud protection and morphological adaptations to enhance their adaptability and resilience in disturbance-prone ecosystems, such as the Cerrado.
