Beyond pollination: diversity of secretory structures during flower development in different legume lineages
Provedor de dados: Acta Botanica Brasilica
Autores: Barros,Thais Cury De; Marinho,Cristina Ribeiro; Pedersoli,Giseli Donizete; Paulino,Juliana Vilella; Teixeira,Simone Pádua.
ABSTRACT Floral secretory structures are usually associated with the attraction of pollinators, but may also play an important role in the mechanisms of plant protection. This study aimed to show the diversity of secretory structures present in the developing flowers of 15 legume species belonging to different clades and to associate them with functions other than the pollinator attraction. Buds, flowers and developing axis of inflorescence were processed for surface, histological, and ultrastructural analyses. The species investigated displayed a wide diversity of secretory structures in developing flowers such as phenolic cells and/or tissues, mucilaginous cells, secretory cavities, secretory trichomes and colleters. Each type of secretory structure...

Elevated atmospheric CO2 increases Eucalyptus urophylla S. T. Blake stem diameter by stimulating cell proliferation and reducing lignin deposition
Provedor de dados: Acta Botanica Brasilica
Autores: Innocente,Patricia Sitta; Teixeira,Simone Pádua; Balbuena,Tiago Santana.
ABSTRACT In 2019, the atmospheric CO2 concentration exceeded the 415 ppm milestone for the first time in the human history. According to projections of the Intergovernmental Panel on Climate Change (IPCC), CO2 levels will continue to rise in the future, potentially affecting all living organisms. Plants with C3 metabolism may benefit from rising CO2 levels because the significant losses of photosynthesis, driven by photorespiration could be diminished under this scenario. This study addressed the anatomical changes in the stems of young Eucalyptus urophylla plants induced through cultivation in elevated CO2 (eCO2). Plants cultivated under eCO2 showed increased stem diameter (i.e., radial width of the secondary xylem, secondary phloem and cortex tissues)....

Trichomes that secrete substances of a mixed nature in the vegetative and reproductive organs of some species of Moraceae
Provedor de dados: Acta Botanica Brasilica
Autores: Schnetzler,Bruna Noce; Teixeira,Simone Pádua; Marinho,and Cristina Ribeiro.
ABSTRACT This study aimed to obtain new information about the distribution, morphology and content of secretory trichomes present in the vegetative and reproductive organs of four species of Moraceae: Artocarpus heterophyllus, Dorstenia cayapia, Maclura tinctoria and Sorocea bonplandii. Stem, leaf, flower and inflorescence samples were processed for scanning electron and light microscopy. The species have secretory trichomes on the leaf blade, petiole and stem and also on the inflorescence and flowers of D. cayapia and S. bonplandii and on the peduncle of the inflorescence in A. heterophyllus. These trichomes are of the capitate type in all species, but A. heterophyllus also possess peltate secretory trichomes. Both trichome types exhibit a multicellular...
