Summary

Phytohormones are important for controlling and coordinating the growth and development of plants, but in recent years, researchers have focused a lot of attention on how they play several roles in plants under changing environments. According to reliable research, phytohormones like auxins, cytokinins, ethylene, and gibberellins, as well as more recent members like brassinosteroids, jasmonates, and strigolactones, may prove to be effective targets for their metabolic processes that make crop plants able to withstand environmental stresses (Kumar et al. 2016). They effectively minimize the negative effects of oxidative stress in plant cells individually or combinedly and provides safeguards towards plant protection from stresses. Additionally, they are employed efficiently for increasing crop production under both normal and stressful settings because of their capacity to promote growth. Several studies demonstrate their efficiency in agricultural productivity. Thus, the use of various phytohormones as a stress management technique will be of interest in the future since it can make our agricultural crops more tolerant to salinity, which is a practical strategy and step toward increasing our prospective crop yields. Remarkable progress has also been made in phytohormone research. This special issue is indented to bring together a galaxy of eminent experienced scientists to present the latest developments in this field.

Elicitation-Based Modulation of Shelf Life in Fruits: Physiological and Molecular Insights
Ankita Kundu, Abir Das, Sayan Pal, Arijit Ghosh, Malay Kumar Adak, Masayuki Fujita, Mirza Hasanuzzaman
Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2283-2300, 2023, DOI:10.32604/phyton.2023.028178

Abstract The process of ripening involves physiological and biochemical events that become a concern during postharvest storage. We have documented different approaches for the preservation and maintenance of fruit quality during the postharvest period that are biocompatible and fully safe for consumption. Chemical residues that sustain sensory characteristics, such as color, flavor, aroma, and texture, are considered. In fruit ripening, both physical and chemical elicitors are described that regulate ethylene biosynthesis or its signaling for gene expression. The key regulatory enzymes, such as ACC synthase and ACC oxidase, for ethylene biosynthesis, are important for both climacteric… More >

Transcriptome Analysis of Auxin Drives Cone Size Regulation in Fokienia hodginsii
Shunde Su, Huan Chang, Xiangyang Kang, Renhua Zheng
Phyton-International Journal of Experimental Botany, Vol.92, No.6, pp. 1713-1723, 2023, DOI:10.32604/phyton.2023.027586

Abstract As the reproductive organ of the endangered species Fokienia hodginsii, the size of the cones is a constraint on the reproductive renewal of the population. In this study, the molecular basis of the influence of cone size on F. hodginsii was elucidated by comparing the phenotype, biochemistry, and transcriptome of two cultivars of F. hodginsii (‘FJ431’ and ‘FJ415’). The two cultivars differed significantly in cone size, with FJ431 having a significantly larger cone size and weight than FJ415, 1.32 and 1.90 times that of FJ415, respectively. RNA-Seq analysis of both cultivars retrieved 75,940 genes whose approximate functions… More >
