Article Abstract
Abscisic acid (ABA) is not only important for plant responses to abiotic stresses, but also plays a key and multifaceted role in plant immunity. In this work, we analyzed the role of ABA in the development of resistance/susceptibility in the wheat ( L.)- Berk. pathosystem, which includes the recognition of the necrotic effectors (NEs) of a pathogen by the corresponding wheat susceptibility genes. We studied the interaction of the SnB isolate, which produces two NEs, SnToxA and SnTox3, with three wheat genotypes having different combinations of the corresponding host susceptibility genes ( and ). The results of this work on the gene expression and redox status of resistant and sensitive wheat genotypes treated with ABA show that ABA signaling is directed at inducing the resistance of wheat plants to SnB isolate through the activation of the early post-invasive defense genes and The induction of the expression of these genes leads to reactive oxygen species (ROS) accumulation during the early stage of infection, with the subsequent limitation of the pathogen's growth. In the presence of a compatible interaction of SnTox3, ABA signaling is suppressed. On the contrary, in the presence of a compatible interaction of , ABA signaling is activated, but the activity of the early post-invasive defense genes and is inhibited, and the expression of the NAC (NAM, ATAF1/2, and CUC2) transcription factor (TF) family genes and is induced. The TF genes and in the presence of SnToxA induce the development of the susceptibility of wheat plants to SnB, associated with a decrease in the oxidative burst during the early stage of infection. Thus, our study provides new data on the role of the NEs SnTox3 and SnToxA in manipulating ABA signaling in the development of the susceptibility of wheat to . Deepening our knowledge in this area will be instrumental for developing new strategies for breeding programs and will contribute to the development of environmentally friendly sustainable agriculture.

Objective: Converging evidence from neuroimaging studies and genome-wide association study (GWAS) suggests the involvement of prefrontal cortex (PFC) and striatum dysfunction in the pathophysiology of anorexia nervosa (AN). However, identifying the causal role of circuit-specific genes in the development of the AN-like phenotype remains challenging and requires the combination of novel molecular tools and preclinical models.
Methods: We used the activity-based anorexia (ABA) rat model in combination with a novel viral-based translating ribosome affinity purification (TRAP) technique to identify transcriptional differences within a specific neural pathway that we have previously demonstrated to mediate pathological weight loss in ABA rats (i.

Seed germination is a critical step in the life cycle of plants. The far-red/red light photoreceptor phytochrome B (phyB) plays a dominant role in promoting seed germination, mainly by modulating the metabolism of gibberellin (GA) and abscisic acid (ABA), although the underlying mechanism remains poorly understood. In this study, we identified BREVIPEDICELLUS (BP)/KNAT1, a KNOX transcription factor that acted downstream of phyB and activated light-initiated seed germination in Arabidopsis thaliana.

Phosphorus (P) is an essential macronutrient for plant growth and development; however, both its deficiency and excess can be harmful. Although the effects of excess P are still poorly understood, research has shown that plants exposed to excessive levels of P exhibit reductions in stomatal conductance, photosynthesis, and growth. The aim of this study was to investigate the effect of different P concentrations on stomatal responses, photochemical parameters, growth, and development of three Solanum lycopersicum genotypes: wild type, Never ripe (lower sensitivity to ethylene), and Notabilis (deficient in ABA production).
