Protective Responses at the Biochemical and Molecular Level Differ between a L. Hybrid and Its Parental Genotypes to Supra-Optimal Temperatures and Elevated Air [CO].

Climate changes with global warming associated with rising atmospheric [CO] can strongly impact crop performance, including coffee, which is one of the most world's traded agricultural commodities. Therefore, it is of utmost importance to understand the mechanisms of heat tolerance and the potential role of elevated air CO (eCO) in the coffee plant response, particularly regarding the antioxidant and other protective mechanisms, which are crucial for coffee plant acclimation. For that, plants of cv.

Intrinsic non-stomatal resilience to drought of the photosynthetic apparatus in Coffea spp. is strengthened by elevated air [CO2].

Growing water restrictions associated with climate changes constitute daunting challenges to crop performance. This study unveils the impacts of moderate (MWD) or severe (SWD) water deficit, and their interaction with air [CO2], on the photosynthetic apparatus of Coffea canephora Pierre ex A. Froehner cv.

Resilient and Sensitive Key Points of the Photosynthetic Machinery of spp. to the Single and Superimposed Exposure to Severe Drought and Heat Stresses.

This study unveils the single and combined drought and heat impacts on the photosynthetic performance of cv. Icatu and cv. Conilon Clone 153 (CL153).

Novel polyol-responsive monoclonal antibodies against extracellular β-D-glucans from Pleurotus ostreatus.

β-D-glucans from mushroom strains play a major role as biological response modifiers in several clinical disorders. Therefore, a specific assay method is of critical importance to find useful and novel sources of β-d-glucans with anti-tumor activity. Hybridoma technology was used to raise monoclonal antibodies (Mabs) against extracellular β-d-glucans (EBG) from Pleurotus ostreatus.

A novel colorimetric assay of β-D-glucans in basidiomycete strains by alcian blue dye in a 96-well microtiter plate.

Basidiomycete strains synthesize several types of β-d-glucans, which play a major role in the medicinal properties of mushrooms. Therefore, the specific quantification of these β-d-glucans in mushroom strains is of great biochemical importance. Because published assay methods for these β-d-glucans present some disadvantages, a novel colorimetric assay method for β-d-glucan with alcian blue dye was developed.

A high throughput colorimetric assay of β-1,3-D-glucans by Congo red dye.

Mushroom strains contain complex nutritional biomolecules with a wide spectrum of therapeutic and prophylactic properties. Among these compounds, β-d-glucans play an important role in immuno-modulating and anti-tumor activities. The present work involves a novel colorimetric assay method for β-1,3-d-glucans with a triple helix tertiary structure by using Congo red.
