One Receptor Show: Evaluation of Feature Extraction Methods for a Single Gas Sensor Based on α-Tocopherol-Substituted Zinc Phthalocyanine.

A consistent part of gas sensor research activities aims to improve sensing performances by synthesizing new sensing materials, improving the selection of elements in arrays, and optimizing the feature extraction and classification algorithms. This paper combines most of these aspects to confer selectivity to a low-selectivity sensor by using feature extraction algorithms applied to the sensor response kinetics. Several algorithms were employed to represent the kinetic behavior of the sensor response during the adsorption and desorption phases.

Identification and expression analysis of phosphate transporter (PHT) genes in Brachypodium distachyon in response to phosphorus deficiency.

Phosphorus (P) is a macronutrient that plays a crucial role in critical plant functions. Phosphate transporters (PHTs) ensure the acquisition and translocation of Pi in the plant, thereby playing a key role in maintaining normal plant growth under Pi deficiency conditions. In Brachypodium distachyon, the grass model system, the function of individual PHT genes, remains largely unknown.

Systematic analysis of Prx genes in the Brachypodium genus and their expression pattern under abiotic constraints.

Peroxiredoxins (Prx) are ubiquitous peroxidases required for the removal of excess free radicals produced under stress conditions. Peroxiredoxin genes (Prx) in the Brachypodium genus were identified using bioinformatics tools and their expression profiles were determined under abiotic stress using RT-qPCR. The promoter regions of Prx genes contain several cis-acting elements related to stress response.

Genetic variability of morpho-physiological response to phosphorus deficiency in Tunisian populations of Brachypodium hybridum.

Brachypodium hybridum (Poaceae) is widely distributed in the dry environments in Mediterranean basin, due to its high tolerance to drought. Investigating the natural variation of B. hybridum in response to environmental stresses is crucial for unraveling the genetic network of its stress tolerance.

Variability in response to salinity stress in natural Tunisian populations of Hordeum marinum subsp. marinum.

Soil salinity is one of the most serious environmental factors affecting crop productivity around the world. In this study, we analysed morpho-physiological variation in responses to salt stress in Tunisian populations of Hordeum marinum subsp. marinum.
