[PMID: 38759757 DOI: 10.1016/j.plantsci.2024.112119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Revised: 05/10/2024] [Accepted: 05/12/2024] [Indexed: 05/19/2024]
Abstract
Domain of unknown function (DUF) protein families, which are uncharacterized and numerous within the Pfam database. Recently, studies have demonstrated that DUFs played crucial roles in plant development, but whether, or how, they function in drought resistance remain unclear. In this study, we identified the Os03g0321500 gene, encoding OsbZIP72 binding protein 1 (OsBBP1), as a target of OsbZIP72 using chromatin immunoprecipitation sequencing in rice. OsBBP1 is a novel member of DUFs, which localize both in the nuclei and cytoplasm of rice protoplasts. Furthermore, yeast one-hybrid and electrophoretic mobility shift assays confirmed the specific binding between OsbZIP72 and OsBBP1. Additionally, a luciferase reporter analysis illustrated that OsbZIP72 activated the expression of OsBBP1. Drought tolerance experiments demonstrate that the OsBBP1 CRISPER-CAS9 transgenic mutants were sensitive to drought stress, but the transgenic OsBBP1 over-expressing rice plants showed enhanced drought resistance. Moreover, drought tolerance experiments in a paddy field suggested that OsBBP1 contributed to less yield or yield-related losses under drought conditions. Mechanistically, OsBBP1 might confer drought resistance by inducing more efficient reactive oxygen species (ROS) scavenging. Several ROS scavenging-related genes showed increased expression levels in OsBBP1 overexpression lines and decreased expression levels in OsBBP1 CRISPER-CAS9 mutants under drought conditions. Thus, OsBBP1, acting downstream of OsbZIP72, contributes to drought resistance and causes less yield or yield-related losses under drought conditions.

Abstract
Domains of unknown function (DUFs), which are deposited in the protein family database (Pfam), are protein domains with conserved amino acid sequences and uncharacterized functions. Proteins with the same DUF were classified as DUF families. Although DUF families are generally not essential for the survival of plants, they play roles in plant development and adaptation. Characterizing the functions of DUFs is important for deciphering biological puzzles. DUFs were generally studied through forward and reverse genetics. Some novelty approaches, especially the determination of crystal structures and interaction partners of the DUFs, should attract more attention. This review described the identification of DUF genes by genome-wide and transcriptome-wide analyses, summarized the function of DUF-containing proteins, and addressed the prospects for future studies in DUFs in plants.

Abstract
Plant species utilize a variety of regulatory mechanisms to ensure sustainable productivity. Within this intricate framework, numerous non-coding RNAs (ncRNAs) play a crucial regulatory role in plant biology, surpassing the essential functions of RNA molecules as messengers, ribosomal, and transfer RNAs. ncRNAs represent an emerging class of regulators, operating directly in the form of small interfering RNAs (siRNAs), microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs). These ncRNAs exert control at various levels, including transcription, post-transcription, translation, and epigenetic. Furthermore, they interact with each other, contributing to a variety of biological processes and mechanisms associated with stress resilience. This review primarily concentrates on the recent advancements in plant ncRNAs, delineating their functions in growth and development across various organs such as root, leaf, seed/endosperm, and seed nutrient development. Additionally, this review broadens its scope by examining the role of ncRNAs in response to environmental stresses such as drought, salt, flood, heat, and cold in plants. This compilation offers updated information and insights to guide the characterization of the potential functions of ncRNAs in plant growth, development, and stress resilience in future research.

Luo C, Akhtar M, Min W, Alam Y, Ma T, Shi Y, She Y, Lu X. The suppressed expression of a stress responsive gene 'OsDSR2' enhances rice tolerance in drought and salt stress. JOURNAL OF PLANT PHYSIOLOGY 2023; 282:153927. [PMID: 36682133 DOI: 10.1016/j.jplph.2023.153927] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 01/13/2023] [Accepted: 01/13/2023] [Indexed: 06/17/2023]
Abstract
Rice is a crucial staple food crop in many countries, yet, abiotic factors like salt and drought impact its growth. The Domain of Unknown Function 966 (DUF966) gene family may be crucial in how rice plants respond to abiotic stress. Our earlier research showed that overexpression of OsDSR2 (DUF966-stress repressive gene 2 in Oryza sativa) decreased resistance to salt and drought stress. To further understand how OsDSR2 negatively affects rice tolerance to salt and drought stress, transgenic rice plants with decreased OsDSR2 expression levels were created employing the RNAi technique. We investigated alterations in rice phenotype, physiology, and differentially expressed genes (DEGs) using a combination of physio-biochemical measurement and RNA-seq analysis. The results of the study demonstrated that rice seedling lines with OsDSR2 knockdown exhibited improved salt and drought stress tolerance. Statistical analysis revealed that the transgenic plants' survival rate (56-68%) was higher than the control plants (30%), in addition to a roughly 3 fold, 3.5 fold, 20% and 10.5% reduction in cell membrane permeability, malondialdehyde (MDA), superoxide anion radical (O2-) and hydrogen peroxide (H2O2) contents, respectively. However, the proline content and antioxidant enzymes (superoxide dismutase (SOD) and peroxidase (POD)) activities were considerably increased by about 5.5 fold, 3.5 fold, and 4.5 fold, respectively, at physiological levels. There were 115 up-regulated and 173 down-regulated DEGs in the leaves of the transgenic lines on the transcriptional regulation under the combined salt-drought stress. Among these, both up-regulation DEGs (e.g., OsHAK5, OsIAA25) and the down-regulation DEGs (e.g., OsbZIP23, OsERF48, OsAP2-39, etc.) may be related to the enhanced tolerance of the transgenic lines under combined salt-drought stress. This possibly depended on the involvement of abscisic acid (ABA) and indoleacetic acid (IAA) signaling pathways. These findings further confirmed that OsDSR2 negatively affected rice's ability to withstand salt and drought, suggesting that it could be a helpful gene for CRISPR-Cas9 technology-based genetic modification of rice's ability to withstand abiotic stress.
