“…During its life cycle, the growth and development of D. catenatum are frequently threatened by environmental conditions, such as temperature and drought stress [37,40]. A lot of stress-related genes or transcription factors were induced to adapt to these environmental stresses [29,33,34,37,40,53]. CHS is a key enzyme in plant secondary metabolic pathways and is associated with many physiological regulations and abiotic stress resistance in plants [54].…”

“…Orchids are the largest family of monocotyledonous plants and have important ornamental value. Dendrobium catenatum belongs to the Dendrobium genus of the Orchidaceae family and is increasingly threatened by adverse environmental conditions [29]. Researchers have often focused on the medicinal properties of D. catenatum [30][31][32], but little is known about its stress resistance [33,34].…”

Flavonoids are considered to be critical metabolites in regulating plant responses to abiotic stress. Chalcone synthase (CHS) catalyzes the first key step in the flavonoid biosynthesis pathway. However, there is no in-depth information on the sequence and functional analysis of CHS genes in Dendrobium catenatum. In this study, a total of 14 DcCHS genes were identified, encoding proteins of 349–504 amino acids in length, a protein molecular weight ranging between 39.08 and 56.56 kDa, and isoelectric points from 5.64 to 9.63. The DcCHS proteins were then divided into three groups according to their phylogenetic relationships. The members of each group had similar conserved motifs and gene structures. Quantitative real-time RT-PCR (RT-qPCR) analysis revealed that the DcCHS genes exhibited variable expression patterns in the different plant tissues evaluated. Furthermore, six genes were differentially expressed following exposure to abiotic stresses: DcCHS-6, DcCHS-5/-6, DcCHS-13/-14, and DcCHS-6/-8/-9/-13, which were specifically expressed in response to drought, heat, cold, and salt stress, respectively. This is the first genome-wide analysis of the CHS genes in D. catenatum, and our findings can provide essential information for a better understanding of the function of DcCHS genes, thus facilitating further research on D. catenatum stress tolerance.

“…These protein kinases play a vital role in transmitting the calcium signals perceived by CBLs to downstream targets, facilitating appropriate plant responses to abiotic stresses [18]. CIPKs typically consist of four domains: a catalytic kinase domain, a regulatory domain containing an auto inhibitory junction and NAF/FISL motif, a junction domain, and a C-terminal domain with a targeting sequence for specific subcellular compartments [3].…”

“…The mechanisms by which traditional Chinese medicinal herbs survive stress are still poorly understood. Zhang et al [3] studied the CBL-CIPK signaling pathway in Dendrobium catenatum, revealing 28 CIPK genes and 9 CBL genes with tissue-specific expression patterns altered by stressors, including heat stress. Using the yeast two-hybrid system, they also discovered 10 CBL-CIPK pairings that interacted with one another.…”

“…Abiotic stressors such as drought, salt, cold, and heat exert profound impacts on plant growth and development. These stressors trigger a cascade of cellular responses, and among the key players orchestrating plant adaptation and resilience is the CBL-CIPK pathway [1][2][3]. The CBL-CIPK pathway comprises two essential elements: calcineurin B-like proteins (CBLs) and CBL-interacting protein kinases (CIPKs) [4].…”

Abiotic stressors, including drought, salt, cold, and heat, profoundly impact plant growth and development, forcing elaborate cellular responses for adaptation and resilience. Among the crucial orchestrators of these responses is the CBL-CIPK pathway, comprising calcineurin B-like proteins (CBLs) and CBL-interacting protein kinases (CIPKs). While CIPKs act as serine/threonine protein kinases, transmitting calcium signals, CBLs function as calcium sensors, influencing the plant’s response to abiotic stress. This review explores the intricate interactions between the CBL-CIPK pathway and plant hormones such as ABA, auxin, ethylene, and jasmonic acid (JA). It highlights their role in fine-tuning stress responses for optimal survival and acclimatization. Building on previous studies that demonstrated the enhanced stress tolerance achieved by upregulating CBL and CIPK genes, we explore the regulatory mechanisms involving post-translational modifications and protein–protein interactions. Despite significant contributions from prior research, gaps persist in understanding the nuanced interplay between the CBL-CIPK system and plant hormone signaling under diverse abiotic stress conditions. In contrast to broader perspectives, our review focuses on the interaction of the pathway with crucial plant hormones and its implications for genetic engineering interventions to enhance crop stress resilience. This specialized perspective aims to contribute novel insights to advance our understanding of the potential of the CBL-CIPK pathway to mitigate crops’ abiotic stress.
