The zinc finger protein (ZFP) family is one of plants’ most diverse family of transcription factors. These proteins with finger-like structural domains have been shown to play a critical role in plant responses to abiotic stresses such as drought. This study aimed to systematically characterize Triticum aestivum ZFPs (TaZFPs) and understand their roles under drought stress. A total of 9 TaC2H2, 38 TaC3HC4, 79 TaCCCH, and 143 TaPHD were identified, which were divided into 4, 7, 12, and 14 distinct subgroups based on their phylogenetic relationships, respectively. Segmental duplication dominated the evolution of four subfamilies and made important contributions to the large-scale amplification of gene families. Syntenic relationships, gene duplications, and Ka/Ks result consistently indicate a potential strong purifying selection on TaZFPs. Additionally, TaZFPs have various abiotic stress-associated cis-acting regulatory elements and have tissue-specific expression patterns showing different responses to drought and heat stress. Therefore, these genes may play multiple functions in plant growth and stress resistance responses. This is the first comprehensive genome-wide analysis of ZFP gene families in T. aestivum to elucidate the basis of their function and resistance mechanisms, providing a reference for precise manipulation of genetic engineering for drought resistance in T. aestivum.

Members of the genus Marinomonas are known for their environmental adaptation and metabolically versatility, with abundant proteins associated with antifreeze, osmotic pressure resistance, carbohydrase and multiple secondary metabolites. Comparative genomic analysis focusing on secondary metabolites and orthologue proteins were conducted with 30 reference genome sequences in genus Marinomonas. In this study, a Gram-stain-negative, rod-shaped, non-agellated and strictly aerobic bacterium, designated as strain E8 T , was isolated from the red algae (Gelidium amansii) in the coastal of Weihai, China. Optimal growth of the strain E8 T was observed at temperatures 25-30 ℃, pH 6.5-8.0 and 1-3% (w/v) NaCl. The DNA G + C content was 42.8 mol%. The predominant quinone was Q-8 and the major fatty acids were C 16:0 , summed feature 3 and summed feature 8. The main polar lipids were phosphatidylglycerol (PG) and phosphatidylethanolamine (PE). Based on data obtained from this polyphasic taxonomic study, strain E8 T belongs to a novel species of the genus Marinomonas, for which the name Marinomonas algarum is proposed. The type strain is E8 T (= KCTC 92201 T = MCCC 1K07070 T ).

Optimal growth of the strain E8T was observed at temperatures 25–30 ℃, pH 6.5-8.0 and 1–3% (w/v) NaCl. The DNA G + C content was 42.8 mol%. The predominant quinone was Q-8 and the major fatty acids were C16:0, summed feature 3 and summed feature 8. The main polar lipids were phosphatidylglycerol (PG) and phosphatidylethanolamine (PE). Based on data obtained from this polyphasic taxonomic study, strain E8T belongs to a novel species of the genus Marinomonas, for which the name Marinomonas algarum is proposed. The type strain is E8T (= KCTC 92201T = MCCC 1K07070T).
