Resumo

Bamboos are known for their economical, ecological, and cultural importance. The plants can be annual or perennial and can be herbs, shrubs or trees and can also show different growth habits. The cell wall is the main component of the mechanical properties of the tissues. Data set presented here contains the results of cell walls fractioning of culms from six neotropical bamboo species: Apoclada simplex, Chusquea capituliflora, Filgueirasia arenicola, Filgueirasia cannavieira, Guadua tagoara, Merostachys riedeliana and Parodiolyra micrantha. The cell walls were fractionated with oxalate and increasing NaOH concentrations sequentially. The yield and the monosaccharide compositions showed a small amount of pectin as expected for Poaceae and arabinoxylan as the main hemicellulose. The digestion of the hemicellulose fraction with xylanase produced an oligosaccharide profile that could be used to compare the similarity of the arabinoxylan from different species without identifying each individual oligosaccharide. Our data showed that the differences in cell wall composition do not vary according to the growth habit, but are in close association with the phylogenetic relations within the family. The differences in load capacity in plants with different habits (trees and herbs, for example) are more associated with the amount of support tissues than with different cell wall compositions. The importance of evaluate the cell wall of tropical bamboo species aimed at improving resources for biotechnology was discussed by Tine et al. 2020 {[}1]. (C) 2020 The Authors.
