The possible regulatory effects of C2H2 zinc finger proteins, which are important transcription factors, on intertidal seaweed responses to abiotic stress unclear. This study was conducted comprehensively analyze the gene family a representative species (Pyropia haitanensis) and clarify its genomic characteristics biological functions. A total 107 PhC2H2 protein-encoding genes distributed five P. haitanensis chromosomes were identified divided into three subgroups. expression levels 85, 61, 58, 45, 41 responded in maturation filaments, high-temperature, salt, low-irradiance, dehydration stress, respectively. conserved during Porphyra evolution, with no indications large-scale genome-wide replication events. On average, had more transposable element (TE) insertions than Pyropia yezoensis umbilicalisC2H2 genes, suggesting that TE may have been main driver expansion. key (PhC2H2.94) screened following quantitative trait locus analysis significantly responsive high-temperature associated photosynthesis, peroxisomes, ubiquitin proteasome pathway, endoplasmic reticulum-related protein processing contribute tolerance haitanensis. Additionally, PhC2H2.94 transgenic Chlamydomonas reinhardtii exhibited increased heat stress. provides new insights genetic resources for characterizing molecular mechanism underlying stresses breeding stress-resistant macroalgae.

WOXs are a class of plant-specific transcription factors that play key roles in plant growth and stress responses. However, the mechanism by which influence adventitious root development Rosa hybrida remains unclear. In this study, RcWOX gene family rose was identified phylogenetically analyzed using bioinformatics analysis. A total 381 members were localized on seven chromosomes except nine members. The main cis -acting elements involved hormonal, light, developmental, abiotic responses promoters genes, suggesting their regulation these signals. Nine RhWOX genes had significant different expression during rooting process rose. RhWOX331 , RhWOX308 RhWOX318 positive with formation roots. positively primordia, coding factor nucleus.

Plant evolution is driven by key innovations of functional traits that enables their survivals in diverse ecological environments. However, plant adaptive from land to atmospheric niches remains poorly understood. In this study, we use the epiphytic Tillandsioideae subfamily Bromeliaceae as model plants explore origin, and diversification. We provide a comprehensive phylogenetic tree based on nuclear transcriptomic sequences, indicating core tillandsioids originated approximately 11.3 million years ago Andes. The geological uplift Andes drives divergence into tank-forming types. Our genomic analyses reveal gene variations losses associated with such impounding tanks absorptive trichomes. Furthermore, uncover specific nitrogen-fixing bacterial communities phyllosphere potential source nitrogen acquisition. Collectively, our study provides integrative multi-omics insights response elevated aerial habitats. mechanisms which adapt habitats remain largely unexplored. Here, authors report link life history, diversification, comparative genomic, changes processes underlying unique biology air plants.

2. Abstract The evolutionary trajectory and genetic architecture of crassulacean acid metabolism (CAM), a water-efficient form photosynthesis that has evolved repeatedly in the plant kingdom, remains elusive. extent to which different CAM phenotypes share basis, forming continuum through varying degrees expression, or exhibit divergence redundancy employed genes their is still debated. subgenus Tillandsia provides an excellent opportunity compare basis forms, given its broad range photosynthetic phenotypes. Through physiological transcriptomic analyses well-watered water-limited accessions closely related species pair, we comprehensively characterized facultative constitutive . By comparing orthologous gene expression orthogroup recruitment, found while both performed upon water-withholding, transcriptional modulation orthogroups stomatal movement, sugar/malate transport, aquaporins starch showed little similarity. Enzymes (de)carboxylation modules exhibited shared patterns, though distinct orthologs PEPC were upregulated at night each species. Our study reveals that, certain core enzymes shared, these substantial CAM-related modulation, revealing CAM’s polygenic nature providing possible hypothesis for evolvability. 1.
