“…Ethylene and auxin pathways are two main pathways involved in hypoxic stress. Furthermore, the coordinated regulation of two signaling pathways is an important mechanism in plants for adapting to stress through plant hormone signals (Habibi et al, 2023). In this study, the genes encoding the protein EBF1/2 were highly expressed in DBH, leading to the stabilization of EIN3 , which was highly expressed in YR.…”

The cotton rose (Hibiscus mutabilis) is a plant species commonly found in tropical and subtropical regions. It is remarkably resilient to waterlogging stress; however, the underlying mechanism behind this trait is yet unknown. This study used hypoxia‐tolerant “Danbanhong” (DBH) and more hypoxia‐sensitive “Yurui” (YR) genotypes and compared their morpho‐physiological and transcriptional responses to hypoxic conditions. Notably, DBH had a higher number of adventitious roots (20.3) compared to YR (10.0), with longer adventitious roots in DBH (18.3 cm) than in YR (11.2 cm). Furthermore, the formation of aerenchyma was 3‐fold greater in DBH compared to YR. Transcriptomic analysis revealed that DBH had more rapid transcriptional responses to hypoxia than YR. Identification of a greater number of differentially expressed genes (DEGs) for aerenchyma, adventitious root formation and development, and energy metabolism in DBH supported that DBH had better morphological and transcriptional adaptation than YR. DEG functional enrichment analysis indicated the involvement of variety‐specific biological processes in adaption to hypoxia. Plant hormone signaling transduction, MAPK signaling pathway and carbon metabolism played more pronounced roles in DBH, whereas the ribosome genes were specifically induced in YR. These results show that effective multilevel coordination of adventitious root development and aerenchyma, in conjunction with plant hormone signaling and carbon metabolism, is required for increased hypoxia tolerance. This study provides new insights into the characterization of morpho‐physiological and transcriptional responses to hypoxia in H. mutabilis, shedding light on the molecular mechanisms of its adaptation to hypoxic environments.

“…In waterlogged or flooded soils, plants suffer from hypoxia stress due to the low level of oxygen (Habibi et al, 2023), an increasingly frequent situation due to extreme events of climate change in plantations near rivers or other bodies of water and their surrounding cities. Due to this adversity, the redox potentials decrease, generating an increase in the solubility of nutrients such as Fe 2+ and Mn 2+ , reaching phytotoxic concentrations in the rhizosphere (Marschner, 2012;Fischer et al, 2023); we assume that some non-essential HM can also reach these harmful levels under waterlogging and inundation conditions.…”

The growth in urbanization and industrialization is causing an increase in environmental pollution in cities and their surrounding areas. Additionally, the growing urban population requires a greater volume of fresh vegetables. In nature, heavy metals (HM) are widely distributed; when they gradually enter the soil-plant-consumer continuum, they are difficult to remove from the system and accumulate at toxic levels. To gain an overview of this situation, the information in the ScienceDirect database was used in accordance with the PRISMA guide. For this, the keywords “vegetable”, “contamination” and “urban” were used in a first step and, in a second step, the keywords “vegetable” and “heavy metal” were used. The most toxic HM for consumers are Cd, Pb, Hg, Cr and As, as well as essential MP for the plant (Zn, Cu, Ni, Fe, Mo). At excessive concentrations these cause neurological and kidney damage, cancer and other forms of damage to health. Crop contamination can come from the atmosphere, irrigation water, and/or the soil itself, proximity to busy roads, industry, polluted rivers, and excessive use of pesticides and fertilizers that contain HM. Plant poisoning by HM causes a decrease in root growth and biomass of the plant, foliar chlorosis, and other physiological alterations. Leafy vegetables (including aromatic herbs) and solanaceous vegetables accumulate the most HM, while cucurbits and legumes are the least affected. Plants that develop for a longer time accumulate a greater amount of HM. In general, to increase the food safety of urban horticulture, more studies are needed on HM contamination, soil aptitude, risk assessment for ingesting intoxicated vegetables, as well as appropriate instructions for the clean handling of these crops in cities and surrounding areas.

“…Interspecific hybrid pumpkin rootstock grafting decreases watermelon fruits taste, total soluble solids (TSS), and sugar content [ 10 ]. According to several studies on tomatoes, watermelon, and other vegetables, the type of rootstock and scion in a grafted tree are related depending on various physiological factors [ 11 ]. Thus, the selection of the appropriate graft combination may be essential for yield efficiency, plant vigour, and fruit quality.…”

Grafting has a significant impact on the botany properties, commercial character, disease resistance, and productivity of eggplants. However, the mechanism of phenotypic modulation on grafted eggplants is rarely reported. In this study, a widely cultivated eggplant (Solanum. melongena cv. ‘Zheqie No.10’) was selected as the scion and grafted, respectively, onto four rootstocks of TOR (S. torvum), Sa (S. aculeatissimum), SS (S. sisymbriifolium), and Sm64R (S. melongena cv. ‘Qiezhen No. 64R’) for phenotypic screening. Physiological and biochemical analysis showed the rootstock Sm64R could improve the fruit quality with the increasing of fruit size, yield, and the contents of total soluble solid, phenolic acid, total amino acid, total sugar, and vitamin C. To further investigate the improvement of fruit quality on Sm64R, a transcriptome and a metabolome between the Sm64R-grafted eggplant and self-grafted eggplant were performed. Significant differences in metabolites, such as phenolic acids, lipids, nucleotides and derivatives, alkaloids, terpenoids, and amino acids, were observed. Differential metabolites and differentially expressed genes were found to be abundant in three core pathways of nutritional qualities, including biosynthesis of phenylpropanoids, phospholipids, and nucleotide metabolism. Thus, this study may provide a novel insight into the effects of grafting on the fruit quality in eggplant.
