Special Issue Information

Dear Colleagues,

Over time, plants have evolved to adapt to the environment. Plant hormones are synthesized via different metabolic routes as part of the secondary metabolism and are small molecules. The classical phytohormones are auxins, gibberellins, cytokinins, abscisic acid, ethylene, and brassinosteroids. In the last few years, compounds such as jasmonates and strigolactones have been added to the list because they function as plant hormones. Plant hormones allow plants to develop in different environments because they regulate many cellular and developmental processes.

Food production from agricultural activity has been affected by the desertification of large cultivation areas, water availability, increased soil salinity, and climate change. As a result, studies about the role of phytohormones in the plant response to abiotic stress have advanced significantly in recent years. This Special Issue plans to provide an overview of the most recent advances in the mechanisms and processes regulated by plant hormones in plants under abiotic stress.

The objectives of this study were to explore the mechanism of stem mechanical strength in direct-seeded rice (DSR) as affected by paclobutrazol, especially its related endogenous hormone and cell wall component changes in culm tissue and response to the application of paclobutrazol. Field experiments were conducted in Changchun County, Jilin Province, China, by using two japonica rice varieties, Jiyujing and Jijing305, with soaking seeds in paclobutrazol at concentrations of (0 mg L−1, S0; 50 mg L−1; S1; 100 mg L−1; S2; 150 mg L−1, S3; 200 mg L−1, S4) in 2021 and 2022. The results suggest that the application of paclobutrazol increased the grain yield and reduced the lodging rate of DSR. Compared with the S0 treatments, soaking the seeds in paclobutrazol treatments rapidly shortened the length of the basal internode by decreasing the endogenous indole acetic acid (IAA) and gibberellin A3 (GA3) contents in culm tissue. The larger breaking strength (M) was attributed to a higher section modulus (SM) and bending stress (BS). The higher mechanical tissue thickness in culm tissue under paclobutrazol treatments, which was raised by higher endogenous zeatin and zeatin riboside (Z+ZR) content in culm tissue, increased the culm diameter, culm wall thickness, and section modulus (SM) of the internode. Compared with the S0 treatments, soaking the seeds in paclobutrazol treatments increased the cellulose content, lignin content, activities of lignin-related enzymes, and expression of key genes in lignin biosynthesis, as well as resulted in a higher bending stress (BS) to enhance the culm breaking strength (M).
