In plants, calcineurin B-like proteins (CBLs) are a unique group of Ca2+ sensors that decode Ca2+ signals by activating a family of plant-specific protein kinases known as CBL-interacting protein kinases (CIPKs). CBL-CIPK gene families and their interacting complexes are involved in regulating plant responses to various environmental stimuli. To gain insight into the functional divergence of CBL-CIPK genes in honeysuckle, a total of six LjCBL and 17 LjCIPK genes were identified. The phylogenetic analysis along with the gene structure analysis divided both CBL and CBL-interacting protein kinase genes into four subgroups and validated by the distribution of conserved protein motifs. The 3-D structure prediction of proteins shown that most LjCBLs shared the same Protein Data Bank hit 1uhnA and most LjCIPKs shared the 6c9Da. Analysis of cis-acting elements and gene ontology implied that both LjCBL and LjCIPK genes could be involved in hormone signal responsiveness and stress adaptation. Protein-protein interaction prediction suggested that LjCBL4 is hypothesized to interact with LjCIPK7/9/15/16 and SOS1/NHX1. Gene expression analysis in response to salinity stress revealed that LjCBL2/4, LjCIPK1/15/17 under all treatments gradually increased over time until peak expression at 72 h. These results demonstrated the conservation of salt overly sensitive pathway genes in honeysuckle and a model of Ca2+-LjCBL4/LjSOS3-LjCIPK16/LjSOS2 module-mediated salt stress signaling in honeysuckle is proposed. This study provides insight into the characteristics of the CBL-CIPK gene families involved in honeysuckle salt stress responses, which could serve as a foundation for gene transformation technology, to obtain highly salt-tolerant medicinal plants in the context of the global reduction of cultivated land.

Autophagy allows for the degradation and recycling of macromolecules and organelles. It plays a significant role in cellular homeostasis, nutrient remobilization during leaf senescence, and abiotic stress responses. Autophagosomes are the hallmark feature of autophagy, and their formation is regulated by the AuTophaGy-related (ATG) genes. The expression profiles of ATG genes have been reported in several agronomic and model plants. To gain insight into the role of autophagy in senescence and abiotic stress responses in floriculture crops, we investigated the regulation of petunia (Petunia ×hybrida) ATG genes (PhATG4, PhATG5, PhATG6, PhATG7, PhATG8a, and PhATG13) during flower senescence and in response to low fertility, nutrient deficiency (-N, -P, and -K), and chronic (weeks) or acute (hours) salt stress using quantitative polymerase chain reaction (PCR). Age-induced corolla wilting coincided with the increased expression of all ATG genes. Petunia ATG genes were upregulated by low fertility and N and P deficiency. Acute salt stress rapidly increased the expression of the petunia ATG genes, but chronic salt stress treatments did not. This project provides insight into the role of autophagy in flower senescence and abiotic stress responses in floriculture crops.
