“…Besides the regulatory role in the growth and development, some ZF-HD genes may play a vital role in response to abiotic stresses such as drought, heat, cold, and salt [ 76 ]. Recent studies indicate that ZF-HD is induced by cold stress, NaCl, and PEG in wheat [ 77 ]. Consistent with all previous reports, we also found the flower gynoecium in CsWUS-OE was smaller than that in WT.…”

WUSCHEL-related homeobox (WOX) transcription factors (TFs) are well known for their role in plant development but are rarely studied in citrus. In this study, we identified 11 putative genes from the sweet orange genome and divided the citrus WOX genes into three clades (modern/WUSCHEL(WUS), intermediate, and ancient). Subsequently, we performed syntenic relationship, intron-exon organization, motif composition, and cis-element analysis. Co-expression analysis based on RNA-seq and tissue-specific expression patterns revealed that CsWOX gene expression has multiple intrinsic functions. CsWUS homolog of AtWUS functions as a transcriptional activator and binds to specific DNA. Overexpression of CsWUS in tobacco revealed dramatic phenotypic changes, including malformed leaves and reduced gynoecia with no seed development. Silencing of CsWUS in lemon using the virus-induced gene silencing (VIGS) system implied the involvement of CsWUS in cells of the plant stem. In addition, CsWUS was found to interact with CsCYCD3, an ortholog in Arabidopsis (AtCYCD3,1). Yeast one-hybrid screening and dual luciferase activity revealed that two TFs (CsRAP2.12 and CsHB22) bind to the promoter of CsWUS and regulate its expression. Altogether, these results extend our knowledge of the WOX gene family along with CsWUS function and provide valuable findings for future study on development regulation and comprehensive data of WOX members in citrus.

“…Promoter region analysis of the MdZF-HD genes identified several cis -elements related to phytohormones and abiotic stresses ( Figure 5 ). Based on the previous studies, ZF-HD family genes were mostly found to participate in the responses to abiotic stresses ( Tan and Irish, 2006 ; Figueiredo et al, 2012 ; Wang et al, 2016 ; Liu et al, 2021 ). For instance, ZF-HD family genes from Arabidopsis, tomato, cucumber, and also apple were shown to be up-regulated by various kinds of stress conditions, such as drought, salt, cold, heat, and phytohormones including GA and ABA ( Shan et al, 2012 ; Zhang et al, 2015 ; Khatun et al, 2017 ; Shalmani et al, 2019 ; Lai et al, 2021 ).…”

Zinc finger-homeodomain (ZF-HD) transcription factors play an important role in the regulation of plant growth and development, as well as the regulation of stress responses. Studies on the ZF-HD family genes have been conducted in many plants, however, the characteristics of this family in apple (Malus domestica) fruit remains to be poorly understood. In this study, we identified nineteen ZF-HD family genes in apple at the whole-genome scale, which were unevenly located on ten chromosomes. These MdZF-HD genes were phylogenetically divided into two subfamilies: zinc finger-homeodomain (ZHD) and MINI ZINC FINGER (MIF), and the ZHD subfamily was further classified into five groups (ZHDI–ZHDV). Analysis of the gene structures showed that most MdZF-HD genes lack introns. Gene expression analysis indicated that nine selected MdZF-HD genes were differentially responsive to 1-MCP (1-methylcyclopropene) treatment during the postharvest storage of “Qinguan” apple fruit. Moreover, the transcripts of six genes were further validated in “Golden Delicious” apple fruit, and five genes (MdZHD1/2/6/10/11) were significantly repressed and one gene (MdZHD7) was slightly induced by ethylene treatment. These results indicated that these six MdZF-HD genes may involve in the regulation of ethylene induced ripening process of postharvest apple fruit. These findings provide new clues for further functional investigation of ZF-HD genes, such as their roles in the regulation of fruit ripening.

“…This was possibly due to the higher expression of several genes that regulate protection against oxidative stress and lipid metabolism, and thus determining cell membrane stability under stress conditions ( Campo et al, 2014 ). The zinc finger super family transcription factors regulate multiple aspects of plant development and abiotic stress tolerance ( Liu et al, 2021 ). Zinc Finger 2 (SlZF2) is rapidly induced by drought in cultivated tomatoes ( Solanum lycopersicum ), and its ectopic expression provides tolerance against salinity stress ( Hichri et al, 2014 ).…”

Effective Use of Water in Crop Plants in Dryland Agriculture: Implications of Reactive Oxygen Species and Antioxidative System

et al. 2022

Under dryland conditions, annual and perennial food crops are exposed to dry spells, severely affecting crop productivity by limiting available soil moisture at critical and sensitive growth stages. Climate variability continues to be the primary cause of uncertainty, often making timing rather than quantity of precipitation the foremost concern. Therefore, mitigation and management of stress experienced by plants due to limited soil moisture are crucial for sustaining crop productivity under current and future harsher environments. Hence, the information generated so far through multiple investigations on mechanisms inducing drought tolerance in plants needs to be translated into tools and techniques for stress management. Scope to accomplish this exists in the inherent capacity of plants to manage stress at the cellular level through various mechanisms. One of the most extensively studied but not conclusive physiological phenomena is the balance between reactive oxygen species (ROS) production and scavenging them through an antioxidative system (AOS), which determines a wide range of damage to the cell, organ, and the plant. In this context, this review aims to examine the possible roles of the ROS-AOS balance in enhancing the effective use of water (EUW) by crops under water-limited dryland conditions. We refer to EUW as biomass produced by plants with available water under soil moisture stress rather than per unit of water (WUE). We hypothesize that EUW can be enhanced by an appropriate balance between water-saving and growth promotion at the whole-plant level during stress and post-stress recovery periods. The ROS-AOS interactions play a crucial role in water-saving mechanisms and biomass accumulation, resulting from growth processes that include cell division, cell expansion, photosynthesis, and translocation of assimilates. Hence, appropriate strategies for manipulating these processes through genetic improvement and/or application of exogenous compounds can provide practical solutions for improving EUW through the optimized ROS-AOS balance under water-limited dryland conditions. This review deals with the role of ROS-AOS in two major EUW determining processes, namely water use and plant growth. It describes implications of the ROS level or content, ROS-producing, and ROS-scavenging enzymes based on plant water status, which ultimately affects photosynthetic efficiency and growth of plants.
