Cell wall hydrolases act in concert during aerenchyma development in sugarcane roots.

Background And Aims: Cell wall disassembly occurs naturally in plants by the action of several glycosyl-hydrolases during different developmental processes such as lysigenous and constitutive aerenchyma formation in sugarcane roots. Wall degradation has been reported in aerenchyma development in different species, but little is known about the action of glycosyl-hydrolases in this process.

Methods: In this work, gene expression, protein levels and enzymatic activity of cell wall hydrolases were assessed.

Diurnal variation in gas exchange and nonstructural carbohydrates throughout sugarcane development.

Photosynthesis and growth are dependent on environmental conditions and plant developmental stages. However, it is still not clear how the environment and development influence the diurnal dynamics of nonstructural carbohydrates production and how they affect growth. This is particularly the case of C4 plants such as sugarcane (Saccharum spp.

Characterization of sugarcane (Saccharum spp.) leaf senescence: implications for biofuel production.

Background: Second-generation ethanol (2G-bioethanol) uses lignocellulosic feedstocks for ethanol production. Sugarcane is one among the most suitable crops for biofuel production. Its juice is extracted for sugar production, while sugarcane bagasse, straw, and senescing leaves are considered industrial waste.
