Eucalyptus urograndis stem proteome is responsive to short-term cold stress
Provedor de dados: 74
Autores: Leonardi,Gabriela de Almeida; Carlos,Natália Aparecida; Mazzafera,Paulo; Balbuena,Tiago Santana.
Eucalyptus urograndis is a hybrid eucalyptus of major economic importance to the Brazilian pulp and paper industry. Although widely used in forest nurseries around the country, little is known about the biochemical changes imposed by environmental stress in this species. In this study, we evaluated the changes in the stem proteome after short-term stimulation by exposure to low temperature. Using two-dimensional gel electrophoresis coupled to high-resolution mass spectrometry-based protein identification, 12 proteins were found to be differentially regulated and successfully identified after stringent database searches against a protein database from a closely related species (Eucalyptus grandis). The identification of these proteins indicated that the E....

In vitro morphogenesis and cell suspension culture establishment in Piper solmsianum C. DC. (Piperaceae)
Provedor de dados: 39
Autores: Balbuena,Tiago Santana; Santa-Catarina,Claudete; Silveira,Vanildo; Kato,Massuo Jorge; Floh,Eny Iochevet Segal.
Piper solmsianum is a shrub from Southeast Brazil in which many biologically active compounds were identified. The aim of this work was to establish a cell suspension culture system for this species. With this in mind, petiole and leaf explants obtained from in vitro plantlets were cultured in the presence of different plant growth regulator combinations (IAA, NAA, 2,4-D and BA). Root and indirect shoot adventitious formation, detected by histological analysis, was observed. Besides the different combinations of plant growth regulators, light regime and the supplement of activated charcoal (1.5 mg.l-1) were tested for callus induction and growth. Cultures maintained in light, on a 0.2 mg.l-1 2,4-D and 2 mg.l-1 BA supplemented medium, and in the absence of...

Elevated atmospheric CO2 increases Eucalyptus urophylla S. T. Blake stem diameter by stimulating cell proliferation and reducing lignin deposition
Provedor de dados: 39
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)....
