Understanding signaling pathways governing the polar development of root hairs in low-temperature, nutrient-deficient environments.

Plants exposed to freezing and above-freezing low temperatures must employ a variety of strategies to minimize fitness loss. There is a considerable knowledge gap regarding how mild low temperatures (around 10 °C) affect plant growth and developmental processes, even though the majority of the molecular mechanisms that plants use to adapt to extremely low temperatures are well understood. Root hairs (RH) have become a useful model system for studying how plants regulate their growth in response to both cell-intrinsic cues and environmental inputs.

A Modeled High-Density Fed-Batch Culture Improves Biomass Growth and β-Glucans Accumulation in .

Algae and microalgae are used as a source of different biomolecules, such as lipids and carbohydrates. Among carbohydrates, polysaccharides, such as β-glucans, are important for their application as antioxidants, antisepsis, and immunomodulators. In the present work, the β-glucans production potential of was assessed using two different culture conditions: a high-density batch and a modeled high-density fed-batch.
