Plant growth regulators (PGRs) play an important role in increasing crop yield, and quality, and enhancing crop stress resistance in agricultural production, especially for important crops. PGRs can affect the transport and distribution of assimilates by changing the content and distribution of endogenous hormones in plants. Numerous empirical research results have proven that PGRs have an important impact on the growth, development, and yield composition of wheat. Taking wheat plants as an example, this study reviews the application of PGRs in wheat production and explores their impact on wheat growth and yield. Furthermore, residues and microbial degradation of PGRs are summarized in detail. Finally, future research directions on PGR application in wheat production are proposed. This summary is of great significance for understanding the role of PGRs in wheat production.

Exploring plant behavior at the cellular scale in a minimally invasive manner is critical to understanding plant adaptation to the environment. Phytohormones play vital regulatory roles in multiple aspects of plant growth and development and acclimation to environmental changes. Since the biosynthesis, modification, transportation, and degradation of plant hormones in plants change with time and space, their content level and distribution are highly dynamic. To monitor the production, transport, perception, and distribution of phytohormones within undamaged tissues, we require qualitative and quantitative tools endowed with remarkably high temporal and spatial resolution. Fluorescent probes are regarded as excellent tools for widespread plant imaging because of their high sensitivity and selectivity, reproducibility, real-time in situ detection, and uncomplicated mechanism elucidation. In this review, we provide a systematical overview of the progress in the sensing and imaging of phytohormone fluorescent probes and fluorescently labeled phytohormones to their receptors in plants. Moreover, forthcoming viewpoints and possible applications of these fluorescent probes within the realm of plants are also presented. We hold the conviction that the new perspective brought by this paper can promote the development of fluorescent probes, enabling them to have better detection performance in plant hormone imaging.

Jasmonic acid is a crucial phytohormone that plays a pivotal role, serving as a regulator to balancing plant development and resistance. However, there are analogous and distinctive characteristics exhibited in JA biosynthesis, perception, and signal transduction pathways in both herbaceous and woody plants. Moreover, the majority of research subjects have predominantly focused on the function of JA in model or herbaceous plants. Consequently, there is a significant paucity of studies investigating JA regulation networks in woody plants, particularly concerning post-transcriptional regulatory events such as alternative splicing (AS). This review article aims to conduct a comprehensive summary of advancements that JA signals regulate plant development across various woody species, comparing the analogous features and regulatory differences to herbaceous counterparts. In addition, we summarized the involvement of AS events including splicing factor (SF) and transcripts in the JA regulatory network, highlighting the effectiveness of high-throughput proteogenomic methods. A better understanding of the JA signaling pathway in woody plants has pivotal implications for forestry production, including optimizing plant management and enhancing secondary metabolite production.

The interactions between plants and herbivorous insects are complex and involve multiple factors, driving species formation and leading to the beginning of co-evolution and diversification of plant and insect molecules. Various molecular processes regulate the interactions between plants and herbivorous insects. Here, we discuss the molecular patterns of plant perception of herbivorous insect feeding through activation of early signaling components, crosstalk of plant defense network composed of multiple plant hormones, and various adaptive changes in insect responses to plant defenses. Both plant defenses and insect counter-defenses are molecular adaptation processes to each other. Molecular models of plant-herbivorous insect interactions can more intuitively help us to understand the co-evolutionary arms race between plants and herbivorous insects. These results will provide detailed evidence to elucidate and enrich the interaction network of plant-herbivorous insects.

Phytohormone is a key regulator of plant growth and development. It has important effects on plant under biotic and abiotic stresses. However, the dose control of phytohormone is always a difficult problem in the application process, which limits the application range of phytohormone. Nanotechnology, because of its characteristics of controlled release, targeted therapy, non-pollution, high adsorption, lower volatilization of active substances, and low dosage of drug, comes into researchers’ vision. Nanomaterials were directly applicated on crops at the early stage, and then active substances, such as pesticides, were encapsulated with nanomaterials, also achieved good results in the field. Currently, more and more attentions have been paid to nano-enabled delivery of phytohormones to plants, and formed a new field in agriculture. In present work, we reviewed the existing literatures, focused on the important regulatory roles of phytohormones in plant growth and development and their application potential, and the development and application prospect of nanomaterials combined with phytohormones were also have been discussed.

Plant growth regulators (PGRs) are a critical regulatory factor that influences plant development and against abiotic or biotic stress. The chemical synthesis of phytohormone analogues represents an effective approach for developing novel PGRs with enhanced bioactivity, reduced costs, and simplified synthesis. This review provides a comprehensive examination of artificially synthesized PGRs (phytohormone structural analogues and functional analogues) over the past five years, emphasizing the synthesis strategy, bioactivity, structure-activity relationships, and target protein. This review argues that the synthesis of functional analogues of phytohormones represents a crucial in the advancement of novel PGRs, and optimization of synthetic procedures would greatly facilitate the commercialization of these PGRs.

The plant defense hormone jasmonates not only play important roles in plant growth, development, and resistance, but also hold promise for bringing new strategies in plant protection and cancer therapy. Recently, de novo biosynthesis of natural and unnatural jasmonates in refactored yeast with integration of 15 heterologous genes and 3 native genes deleted was reported. Here, we highlight the feasible and sustainable platform to efficiently produce jasmonates, which would benefit both agriculture and human health.

Continued population growth and limited land availability will facilitate the utilization of plant growth regulators (PGRs) in sustainable agriculture to enhance crop yields. The PGRs industry has progressed significantly from 2003 to 2022, resulting in a surge of research activities in the field of PGRs. However, the existing studies lack the exploration of the industry trends, as well as the challenges and opportunities for innovation in PGR development. Here, we analyze the dynamic trends within the PGR industry by examining key factors such as the PGR market, patent applications, scientific papers, and PGRs registrations from 2003 to 2022. Additionally, we investigate the specific effects of major agrochemicals on plants. These data will provide essential insights into the ongoing evolution and future trends of PGRs. Importantly, it is crucial to actively pursue research and development (R&D) of a broader range of PGRs to respond to the current needs of the PGR market and drive further growth therein.
