Advances in fungal sugar transporters: unlocking the potential of second-generation bioethanol production.

Second-generation (2G) bioethanol production, derived from lignocellulosic biomass, has emerged as a sustainable alternative to fossil fuels by addressing growing energy demands and environmental concerns. Fungal sugar transporters (STs) play a critical role in this process, enabling the uptake of monosaccharides such as glucose and xylose, which are released during the enzymatic hydrolysis of biomass. This mini-review explores recent advances in the structural and functional characterization of STs in filamentous fungi and yeasts, highlighting their roles in processes such as cellulase induction, carbon catabolite repression, and sugar signaling pathways.

The arabidopsis phytoglobin 1 (Pgb1) involvement in somatic embryogenesis is linked to changes in ethylene and the class VII ethylene transcription factor HRE2.

Phytoglobin1 promotes Arabidopsis somatic embryogenesis through the mediation of ethylene and the ERFVII HRE2. Generation of somatic embryos in Arabidopsis (Arabidopsis thaliana) is a two-step process, encompassing an induction phase where embryogenic tissue (ET) is formed followed by a developmental phase encouraging the growth of the embryos. Using previously characterized transgenic lines dysregulating the class 1 Phytoglobin (Pgb1) we show that suppression of Pgb1 decreases somatic embryogenesis (SE).

Self-powered Wraparound (Abaxial) Droplet Deposition via a Superhydrophobic Surface Aid.

Many diseases and pests are fond of the backs of leaves, making wraparound deposition essential for enhancing agrochemical utilization and minimizing environmental hazards. We present a superhydrophobic surface decorated with fluorinated-SiO nanoparticles on the adaxial (front) side, improving sprayed droplet wraparound behaviors and achieving a 10-fold increase in abaxial (backside) deposition without using an electrostatic sprayer. Solid-liquid contact electrification boosts the positive charge-to-mass ratio of rebound spraying from 17 to 454 nC g, with the abaxial surface acquiring opposite electric charges at kilovolt-level voltages.

The wheat NLR pair RXL/Pm5e confers resistance to powdery mildew.

Powdery mildew poses a significant threat to global wheat production and most cloned and deployed resistance genes for wheat breeding encode nucleotide-binding and leucine-rich repeat (NLR) immune receptors. Although two genetically linked NLRs function together as an NLR pair have been reported in other species, this phenomenon has been relatively less studied in wheat. Here, we demonstrate that two tightly linked NLR genes, RXL and Pm5e, arranged in a head-to-head orientation, function together as an NLR pair to mediate powdery mildew resistance in wheat.

The Interaction Between ABA and Sugar Signalling Regulates Stomatal Production in Systemic Leaves by Controlling Sucrose Transport.

A key feature of stress responses [closely relative to the phytohormone abscisic acid (ABA)] and associated acclimation in plants is the dynamic adjustments and related optimisation of carbohydrate content between sink and source organs. The production of stomata, which consist of a pore between two adjacent guard cells, are central to plant adaptation to changing environment conditions. In this context, ABA is a core modulator of environmentally determined stomatal development.

Disentangling Effects of Vegetation Structure and Physiology on Land-Atmosphere Coupling.

The role of light in regulating plant growth, development and sugar metabolism: a review.

Light provides the necessary energy for plant photosynthesis, which allows plants to produce organic matter and energy conversion, during plant growth and development. Light provides material energy to plants as the basis for cell division and differentiation, chlorophyll synthesis, tissue growth and stomatal movement, and light intensity, photoperiod, and light quality play important roles in these processes. There are several regulatory mechanisms involved in sugar metabolism in plants, and light, as one of the regulatory factors, affects cell wall composition, starch granules, sucrose synthesis, and vascular bundle formation.
