“…OsBRI1 and its homologs OsBRL1 and OsBRL3 have also been reported in shoot cell elongation and cell division as well as root development ( Yamamuro et al., 2000 ; Nakamura et al., 2006 ). The wheat TaBRI1 is BR-dependent and responsible for earlier flowering time and higher seed yield in Arabidopsis ( Table 2 ) ( Singh et al., 2016 ; Rafeie et al., 2020 ; Sharma and Khurana, 2022 ). Abscisic acid (ABA), however, is mostly reported to be involved in the regulation of abiotic stresses via indirect interactions with RLKs, unlike BRs.…”

All living organisms must develop mechanisms to cope with and adapt to new environments. The transition of plants from aquatic to terrestrial environment provided new opportunities for them to exploit additional resources but made them vulnerable to harsh and ever-changing conditions. As such, the transmembrane receptor-like kinases (RLKs) have been extensively duplicated and expanded in land plants, increasing the number of RLKs in the advanced angiosperms, thus becoming one of the largest protein families in eukaryotes. The basic structure of the RLKs consists of a variable extracellular domain (ECD), a transmembrane domain (TM), and a conserved kinase domain (KD). Their variable ECDs can perceive various kinds of ligands that activate the conserved KD through a series of auto- and trans-phosphorylation events, allowing the KDs to keep the conserved kinase activities as a molecular switch that stabilizes their intracellular signaling cascades, possibly maintaining cellular homeostasis as their advantages in different environmental conditions. The RLK signaling mechanisms may require a coreceptor and other interactors, which ultimately leads to the control of various functions of growth and development, fertilization, and immunity. Therefore, the identification of new signaling mechanisms might offer a unique insight into the regulatory mechanism of RLKs in plant development and adaptations. Here, we give an overview update of recent advances in RLKs and their signaling mechanisms.

“…The study found that the pollen tube growth in single and double knockout mutants of perk5-1 and perk12-1 was damaged with defective male gametophytes, and excessive pectin and cellulose accumulation was shown on the cell wall of the pollen tube [ 28 ]. Thermo-Sensitive Genic Male Sterile 10 (TMS10) and TMS10-LIKE (TMS10L), members of the rice LRR-RLK subfamily, are related to tapetal degeneration and pollen vitality [ 36 ]. OsLecRK5 can phosphorylate the callose synthase UDP glucose pyrophosphorylase 1 (UGP1) during the meiosis of rice anther microspore mother cells and promote its activity in callose biosynthesis [ 37 ].…”

Accompanying the process of growth and development, plants are exposed to ever-changing environments, which consequently trigger abiotic or biotic stress responses. The large protein family known as receptor-like protein kinases (RLKs) is involved in the regulation of plant growth and development, as well as in the response to various stresses. Understanding the biological function and molecular mechanism of RLKs is helpful for crop breeding. Research on the role and mechanism of RLKs has recently received considerable attention regarding the balance between plant growth and environmental adaptability. In this paper, we systematically review the classification of RLKs, the regulatory roles of RLKs in plant development (meristem activity, leaf morphology and reproduction) and in stress responses (disease resistance and environmental adaptation). This review focuses on recent findings revealing that RLKs simultaneously regulate plant growth and stress adaptation, which may pave the way for the better understanding of their function in crop improvement. Although the exact crosstalk between growth constraint and plant adaptation remains elusive, a profound study on the adaptive mechanisms for decoupling the developmental processes would be a promising direction for the future research.

“…PGRs are naturally occurring hormones or synthetic analogs that significantly affect plants, even at low concentrations, and can regulate cell division, cell elongation, and gene expression (Basra, 2000;Nambara and Marion-Poll, 2005;Teale et al, 2006;Rostami et al, 2016). Various PGRs regulate the mechanism of action of phytohormones, such as auxin, abscisic acid (ABA), brassinosteroid, cytokinin, ethylene, gibberellin acid (GA), jasmonic acid, salicylic acid, and strigolactone (Rajala et al, 2002;Ault and Siqueira, 2008;Carey et al, 2008;Gopi et al, 2009;Anosheh et al, 2012;Choudhury et al, 2013;Banerjee and Roychoudhury, 2018;Rafeie et al, 2020;Raza et al, 2021).…”

Exogenous Gibberellin Application in Tomato (Solanum lycopersicum) Recovers Growth Inhibition Caused by Triazole Overuse

Tomatoes are widely used worldwide and are an economically important crop. Tomatoes contain important secondary metabolites, as well as lycopene, β-carotene, vitamin C, and flavonoids. The quality of tomato seedlings varies depending on certain environmental factors during the seedling growth season. In Korea, diniconazole (DIN), a triazole-based plant growth regulator (PGR), is widely used to prevent seedling overgrowth. Misapplication of a triazole-based PGR results in excessive growth inhibition. However, little is known about the prevention of side effects such as growth inhibition after a DIN treatment. Therefore, this study sought to determine whether growth inhibition could be resolved by treatment with GA 3 , a phytohormone, after a DIN treatment. This study compared the survival rates of seedlings after a DIN treatment and analyzed the growth of tomato seedlings treated with GA 3 after a DIN treatment. To this end, DIN was diluted to a concentration of 250 mg•L -1 to be treated at 3 mg per plant, and GA 3 was diluted to a concentration of 5 mg•L -1 and 10 mg•L -1 to be treated at 2.5 mL per plant. GA 3 was administered up to two times per concentration. In the foliar application of GA 3 after the DIN treatment, no difference in growth was found between the treatments at different concentrations, but there was a significant difference between plants subjected to the single and double treatments. The results of this study suggest that a GA 3 treatment at a higher frequency than a high-concentration treatment can more effectively address the growth inhibition issue associated with a DIN treatment.
