Determinant factors for epiphyte-phorophyte interactions in patches of cloud forest within a matrix of campos rupestres [PDF]

Acta Botânica Brasílica
The epiphytic flora is influenced by the architecture and morpho-physiology of phorophytes. Our knowledge about the ecology of these communities remains limited, especially in the campos rupestres.

Production of added value bacterial lipids through valorisation of hydrocarbon-contaminated cork waste [PDF]

, 2017
This work demonstrates that cork used as oil-spill sorbents, contaminated with liquid hydrocarbons, herein demonstrated with hexadecane, can be biologically treated by Rhodococcus opacus B4 with concomitant lipids production. R.

Antiproliferative action of aqueous extracts of Hymenaea stigonocarpa Mart. (Fabaceae) on the cell cycle of Allium cepa L.

Anais da Academia Brasileira de Ciências, 2014
In this study we evaluated the action of crude aqueous extracts obtained from rhytidome of Hymenaea stigonocarpa (jatobá-do-cerrado) on Allium cepa meristematic root cells in three concentrations: 0.082, 0.164, 0.328g/mL, at exposure times of 24 and 48 h.

Moving carbon between spheres, the potential oxalate-carbonate pathway of Brosimum alicastrum Sw.; Moraceae. [PDF]

, 2016
Aims The Oxalate-Carbonate Pathway (OCP) is a biogeochemical process that transfers atmospheric CO2 into the geologic reservoir as CaCO3; however, until now all investigations on this process have focused on species with limited food benefits. This study

The Making of Plant Armor : The Periderm [PDF]

, 2022
The periderm acts as armor protecting the plant's inner tissues from biotic and abiotic stress. It forms during the radial thickening of plant organs such as stems and roots and replaces the function of primary protective tissues such as the epidermis ...

Tissue‐specific study across the stem reveals the chemistry and transcriptome dynamics of birch bark

New Phytologist, Volume 222, Issue 4, Page 1816-1831, June 2019., 2019
Summary Tree bark is a highly specialized array of tissues that plays important roles in plant protection and development. Bark tissues develop from two lateral meristems; the phellogen (cork cambium) produces the outermost stem–environment barrier called the periderm, while the vascular cambium contributes with phloem tissues. Although bark is diverse

Bark Thickness Equations for Mixed‐Conifer Forest Type in Klamath and Sierra Nevada Mountains of California

International Journal of Forestry Research, Volume 2016, Issue 1, 2016., 2016
We studied bark thickness in the mixed‐conifer forest type throughout California. Sampling included eight conifer species and covered latitude and elevation gradients. The thickness of tree bark at 1.37 m correlated with diameter at breast height (DBH) and varied among species.
