A Positive Role for CaMEKK17 in Response to Drought Stress, Modulated by Clade A PP2Cs.

The abscisic acid (ABA) signaling pathway is essential for plant response to abiotic stresses and can be modulated positively or negatively by MAPKKK proteins. This study focuses on the functional characterization of CaMEKK17, a MAPKKK previously recognized for its rapid induction under drought stress. Functional analyses demonstrated that CaMEKK17 is an active serine/threonine kinase with a conserved catalytic domain that is crucial for its kinase activity.

Pepper SnRK2.6-activated MEKK protein CaMEKK23 is directly and indirectly modulated by clade A PP2Cs in response to drought stress.

The phytohormone abscisic acid (ABA) is important for the plant growth and development, in which it plays a key role in the responses to drought stress. Among the core components of ABA signaling, SnRK2s interact with a range of proteins, including Raf-like MAP3Ks. In this study, we isolated the pepper MEKK subfamily member CaMEKK23 that interacts with CaSnRK2.

CaADIP1-dependent CaADIK1-kinase activation is required for abscisic acid signalling and drought stress response in Capsicum annuum.

Induction of the abscisic acid (ABA) signalling network is associated with various stress conditions, including cold, high salinity and drought. As core ABA signalling components, group A type 2C protein phosphatases (PP2Cs) interact with and inhibit snf1-related protein kinase2s. Here, we isolated and characterised the pepper mitogen-activated protein kinase kinase kinase CaADIK1, which interacts with the group A PP2C CaADIP1.

Mitogen-Activated Protein Kinase Functions as a Positive Regulator of Drought Stress Response and Abscisic Acid Signaling in .

Protein phosphorylation by kinase is an important mechanism for adapting to drought stress conditions. Here, we isolated the () from dehydrated pepper leaf tissue and functionally characterized it. Subcellular localization analysis revealed that the CaDIMK1 protein was localized in the cytoplasm and nucleus.

A Study on Carbon Capture and Storage and Its Feasibility in Energy-Environment Technologies.

Carbon capture and storage (CCS) has the potential to play an important role in managing global warming in the near future. Herein, we define the entire energy cycle from energy production to utilization considering energy-environment technologies and describe the technical classification and brief technical principles of CCS technology. In addition, we evaluate data from actual scenarios and costs of various indicators established from diverse reports published by reliable institutes on various energy-environment technologies.

Differential expression of MEKK subfamily genes in L. in response to abscisic acid and drought stress.

Mitogen-activated protein kinase kinase kinases (MAPKKKs or MEKKs) are crucial components of the MAPK signaling cascades, which play central roles in the signaling transduction pathways for plant growth, development, and response to abiotic stresses such as drought. The MAPKKK gene families in pepper have not been functionally characterized yet. Here, from the pepper genome, we predicted 27 putative MAPKKK genes belonging to the MEKK subfamily (named ), based on analysis.

The Pepper MAP Kinase CaAIMK1 Positively Regulates ABA and Drought Stress Responses.

Protein phosphorylation and dephosphorylation are important mechanisms that regulate many cellular processes. Protein kinases usually function in the regulation of the stress responses by adjusting activity via phosphorylation of target proteins. Here, we isolated ( ABA Induced MAP Kinase 1) from the pepper leaves that had been subjected to drought stress.
