“…This E3 ligase is highly expressed under drought conditions, and compared to wildtype, ospub41 null mutants have enhanced tolerance towards water deficit stress [ 65 ]. OsPUB41 triggers the degradation of CHLORIDE CHANNEL 6 (OsCLC6), a protein critical for drought stress tolerance [ 65 ], and part of a family that functions in modifying chlorine ion homeostasis under drought conditions [ 174 ] ( Figure 3 ).…”

Plants, as sessile organisms, have limited means to cope with environmental changes. Consequently, they have developed complex regulatory systems to ameliorate abiotic stresses im-posed by environmental changes. One such system is the ubiquitin proteasome pathway, which utilizes E3 ligases to target proteins for proteolytic degradation via the 26S proteasome. Plants ex-press a plethora of E3 ligases that are categorized into four major groups depending on their structure. They are involved in many biological and developmental processes in plants, such as DNA repair, photomorphogenesis, phytohormones signaling, and biotic stress. Moreover, many E3 ligase targets are proteins involved in abiotic stress responses, such as salt, drought, heat, and cold. In this review, we will provide a comprehensive overview of E3 ligases and their substrates that have been connected with abiotic stress in order to illustrate the diversity and complexity of how this pathway enables plant survival under stress conditions.

“…Four protein families including nitrate transporter 1 (NRT1)/peptide transporter (PTR) family (subsequently known as unified nomenclature NPF), nitrate transporter 2 (NRT2) family, chloride channel (CLC) family, and slow anion channelassociated homologs (SLAC/SLAH) family are involved in nitrate transport [19,20]. In rice, there are 94 NPF [21,22], 5 NRT2 [23], 5 CLC [24], and 9 SLAC1/SLAH [25] members.…”

“…Plant CLCs transporters are critical for uptake and transport of Cl − and nitrate under salt stress [47,48]. The rice genome contains five CLC genes, but their functional roles for nitrate transport have not been reported so far [24]. Instead, the tonoplast-localized OsCLC1 and OsCLC2 proteins function in compartmentalizing Cl − into the vacuole to avoid the toxicity of Cl − under salt stress conditions, and overexpression of OsCLC1 promotes drought tolerance, leading to better grain yield [24,49].…”

Rice (Oryza sativa L.) is a daily staple food crop for more than half of the global population and improving productivity is an important task to meet future demands of the expanding world population. The application of nitrogen (N) fertilization improved rice growth and productivity in the world, but excess use causes environmental and economic issues. One of the main goals of rice breeding is reducing N fertilization while maintaining productivity. Therefore, enhancing rice nitrogen use efficiency (NUE) is essential for the development of sustainable agriculture and has become urgently needed. Many studies have been conducted on the main steps in the use of N including uptake and transport, reduction and assimilation, and translocation and remobilization, and on transcription factors regulating N metabolism. Understanding of these complex processes provides a base for the development of novel strategies to improve NUE for rice productivity under varying N conditions.

“…As part of a mechanism associated with salt stress, members of the chloride channel protein (CLC) family, which is found in prokaryotes and eukaryotes, play an important role in ion homeostasis [ 35 , 36 ]. A characterized example in rice is the OsCLC1 protein, which is located at the tonoplast in the cell [ 37 ], and overexpression of OsCLC1 in rice was found to enhance drought stress tolerance through modulating jasmonic acid (JA) signaling [ 38 ]. We predicted the uORF in OsCLC1 transcripts using uORFFlight ( accessed on 20 February 2021) and identified a type 1 uORF in the 5’UTR.…”

Global population growth and climate change are posing increasing challenges to the production of a stable crop supply using current agricultural practices. The generation of genetically modified (GM) crops has contributed to improving crop stress tolerance and productivity; however, many regulations are still in place that limit their commercialization. Recently, alternative biotechnology-based strategies, such as gene-edited (GE) crops, have been in the spotlight. Gene-editing technology, based on the clustered regularly interspaced short palindromic repeats (CRISPR) platform, has emerged as a revolutionary tool for targeted gene mutation, and has received attention as a game changer in the global biotechnology market. Here, we briefly introduce the concept of upstream open reading frames (uORFs) editing, which allows for control of the translation of downstream ORFs, and outline the potential for enhancing target gene expression by mutating uORFs. We discuss the current status of developing stress-tolerant crops, and discuss uORF targets associated with salt stress-responsive genes in rice that have already been verified by transgenic research. Finally, we overview the strategy for developing GE crops using uORF editing via the CRISPR-Cas9 system. A case is therefore made that the mutation of uORFs represents an efficient method for developing GE crops and an expansion of the scope of application of genome editing technology.
