“…Some halophytes, i.e., recretohalophytes, have evolved salt glands, which expel salt out of the plant body to maintain the proper salt balance (Feng et al, 2014;Leng et al, 2019a;Yuan et al, 2019a). Salt glands are mainly distributed on the surfaces of the stems and leaves of recretohalophytes (Leng et al, 2018(Leng et al, , 2019b.…”

Plant epidermal cells, such as trichomes, root hairs, salt glands, and stomata, play pivotal roles in the growth, development, and environmental adaptation of terrestrial plants. Cell fate determination, differentiation, and the formation of epidermal structures represent basic developmental processes in multicellular organisms. Increasing evidence indicates that C2H2 zinc finger proteins play important roles in regulating the development of epidermal structures in plants and plant adaptation to unfavorable environments. Here, we systematically summarize the molecular mechanism underlying the roles of C2H2 zinc finger proteins in controlling epidermal cell formation in plants, with an emphasis on trichomes, root hairs, and salt glands and their roles in plant adaptation to environmental stress. In addition, we discuss the possible roles of homologous C2H2 zinc finger proteins in trichome development in non-halophytes and salt gland development in halophytes based on bioinformatic analysis. This review provides a foundation for further study of epidermal cell development and abiotic stress responses in plants.

“…For instance, high sodium chloride levels delay seed germination in soybean ( Glycine max ) by negatively regulating GA biosynthesis while inducing ABA biosynthesis, leading to a decrease in the GA/ABA ratio . Melatonin promotes ABA catabolism and GA biosynthesis in Limonium bicolor under salt stress by upregulating key genes involved in GA biosynthesis ( GA20ox and GA3ox ) and downregulating key genes involved in ABA biosynthesis ( LbNCED1 and LbNCED3 ) to promote germination. − Thus GAs promote the initiation of leaf primordia under salt stress. In addition, the role of ETH in plant responses to salt stress is well known.…”

Phytohormones participate in various processes over the course of a plant’s lifecycle. In addition to the five classical phytohormones (auxins, cytokinins, gibberellins, abscisic acid, and ethylene), phytohormones such as brassinosteroids, jasmonic acid, salicylic acid, strigolactones, and peptides also play important roles in plant growth and stress responses. Given the highly interconnected nature of phytohormones during plant development and stress responses, it is challenging to study the biological function of a single phytohormone in isolation. In the current Review, we describe the combined functions and signaling cascades (especially the shared points and pathways) of various phytohormones in leaf development, in particular, during leaf primordium initiation and the establishment of leaf polarity and leaf morphology as well as leaf development under various stress conditions. We propose a model incorporating the roles of multiple phytohormones in leaf development and stress responses to illustrate the underlying combinatorial signaling pathways. This model provides a reference for breeding stress-resistant crops.

“…Salt glands are a typical salt secretory epidermal structure that are present in 68 species, including sea lavender ( L. bicolor ) ( Li et al., 2020 ; Lu et al., 2020 ). L. bicolor belongs to the Plumbaginaceae ( Yuan et al., 2016a ; Leng et al., 2018 ; Yuan et al., 2018 ; Leng et al., 2019a ; Leng et al., 2019b ; Guo et al., 2020b ; Gao et al., 2021 ) and is a unique recretohalophyte with a sequenced genome that constitutes an essential genetic resource for improving salt tolerance in crops. Salt gland differentiation is the earliest visible sign on the epidermis, even before the development of stomata and other epidermal structures.…”

Halophytes can grow and reproduce in high-salinity environments, making them an important reservoir of genes conferring salt tolerance. With the expansion of saline soils worldwide, exploring the mechanisms of salt tolerance in halophytes and improving the salt tolerance of crops have become increasingly urgent. Limonium bicolor is a halophyte with salt glands that secrete excess Na+ through leaves. Here, we identified an uncharacterized gene Lb1G04794, which showed increased expression after NaCl treatment and was high during salt gland development in L. bicolor. Overexpression of Lb1G04794 in L. bicolor showed promoted salt gland development, indicating that this gene may promote salt gland differentiation. Transgenic Arabidopsis strains overexpressing Lb1G04794 showed increased trichomes and decreased root hairs under normal conditions. Compared with wild type (WT), root growth in the transgenic lines was less inhibited by NaCl treatment. Transgenic seedlings accumulated less fresh/dry weight reductions under long-term salt treatment, accompanied by lower Na+ and malondialdehyde accumulation than WT, indicating that these transgenic lines behave better growth and undergo less cellular damage under NaCl stress. These results were consistent with the low expression levels of salt-tolerance marker genes in the transgenic lines upon salt stress. We conclude that the unknown gene Lb1G04794 positively regulated salt gland development, and promoted salt tolerance of Arabidopsis, offering a new direction for improving salt tolerance of non-halophytes and crops.
