Summary: The Estrogen Related Receptor (ERR) nuclear hormone receptor genes play diverse roles in vertebrate development. In embryos, ERR genes are expressed in various tissues, particularly the nervous system. Most jawed vertebrates and lampreys have four ERR paralogues, which are ancestrally linked to Estrogen Receptor genes. Conserved non-coding sequences in ERR introns are found to be regulatory and drive gene expression in the nervous system.

Summary: The plastomes of Gastrodieae, a mycoheterotrophic clade of the Orchidaceae family, are characterized by reduced structure and gene content, low GC content, rrn block formation, lineage-specific reconfiguration, and positive selection. They serve as an excellent model for studying plastome evolution and provide insights into plastome evolution in parasitic plants.

Summary: Comparative approaches in studying chordate genomes have revealed the significance of gene duplications, including whole genome duplications, in the evolution of gene families. Duplicated genes are key in developmental biology and play a role in major evolutionary transitions, with mechanisms such as retention, subfunctionalization, neofunctionalization, and specialization. Understanding the impact of gene duplication on chordate evolution, including the retention and loss patterns of duplicated genes, remains a complex topic that requires further exploration with the help of sequencing projects and genomic resources.

Summary: Despite the highly regionalized molecular structure of the amphioxus neural tube, little is known about the morphogenetic mechanisms regulating the emergence of specific cell types at distinct sites in the nervous system. Proliferation plays a crucial role in shaping and regionalizing the amphioxus neural axis during development, with specific regions depending on proliferation at precise time-points for their maturation. This study highlights the importance of tightly controlled proliferation in establishing the cell type repertoire and influencing tissue geometry in amphioxus embryos.

Summary: Nodule development requires spatiotemporal coordination between root epidermis and root cortex. In this study, we found that IAA carboxyl methyltransferase 1 (IAMT1) is transiently induced in wild-type roots at early stages of infection, but shows different expression dynamics in the mutant daphne. Knockdown of one of the IAMT1s, IAMT1a, inhibits nodule development in the root cortex. We also observed an increase in root MeIAA levels with rhizobial infection, and application of MeIAA induces expression of the symbiotic gene NIN in the absence of infection.

Summary: The study reveals the importance of centriolar protein Bld10p in the formation of centriole structural symmetry, particularly in the cartwheel-independent mechanism. Bld10p plays a role in determining the inter-triplet distance and regulating the centriole structure in the absence of the cartwheel.

Summary: In Ciona intestinalis, while adult stem cells in the branchial sac vasculature proliferate and progenitor cells migrate to the site of distal injury, regeneration only occurs in the proximal fragments. By analyzing the transcriptome of regenerating animals, we found that the chaperone system genes hsp70, dnaJb4, and bag3 are significantly upregulated in the branchial sac vasculature following distal injury. The upregulation of these heat shock protein genes is crucial for regeneration.

Summary: The study reveals that bone marrow derived macrophages from male mice infected with Schistosoma mansoni have long-lasting increases in lipid metabolism and this metabolic reprogramming can be transferred to uninfected hosts through bone marrow transplantation. Furthermore, the polarization of type-2 cytokines is not enough to replicate the infection-induced metabolic changes, indicating a unique and long-lasting reprogramming of macrophage metabolic signature induced by helminth infection.

Summary: ANp63 is crucial in maintaining and renewing myoepithelial cells in the salivary glands. These cells function as bipotent progenitor cells during homeostasis and contribute to the differentiation of ductal and acinar cells. However, their contribution to regeneration following severe injury is independent of delta Np63.

Summary: This study identified the prevalence of GI-19 and GI-7 subtypes of infectious bronchitis virus (IBV) in China and investigated the evolution and transmission dynamics of the GI-7 subtype. The results suggested that the GI-7 subtype originated from Taiwan and spread mainly in South China, with low codon usage bias in the S1 gene. The findings provide valuable insights for the prevention and control of viral infection.

Summary: Species delimitation among closely related species remains challenging due to discrepancies between traditional phenotype-based approaches and natural groupings. High-throughput sequencing has made it more cost-effective to acquire genome-scale data, allowing for the resolution of ambiguous species boundaries. Despite the development of various species delimitation analyses, such as BPP and SNAPP+BFD, empirical molecular approaches may still be biased by confounding factors, leading to inconsistent results. Cross-validating results between different datasets and controlling for genetic divergence at the population level can improve the reliability of species delimitation.

Summary: The epidermis of a cephalochordate undergoes changes in cell arrangement and structure after tail amputation, with cells initially dispersing before returning to a close hexagonal grid pattern. Additionally, there is a temporary formation of intercellular gaps near the regenerating tail, which eventually closes up and reverts back to the original close association between cells.

Summary: This study compared the microbial assemblages obtained from Atlantic salmon gills using swabbing and biopsy excision, revealing clear divergence in microbial communities obtained through different sampling strategies. Swabbing consistently isolated a more diverse microbial consortia, while biopsy extraction hinted at potential for more cryptic localization of some community members. Overall, the study highlights the importance of considering different sampling methods when studying fish microbiomes.

Summary: Wnt signaling is essential for animal development, regeneration and also plays a role in diseases. TCF/LEF proteins mediate Wnt/beta-catenin-regulated gene expression. Vertebrates possess a high diversity of TCF/LEF family genes compared to invertebrates, suggesting changes in Wnt signaling during vertebrate evolution. This study clarifies the relationships within the TCF/LEF gene family in chordates through comparative analysis of gene structure, molecular phylogeny, and gene synteny. The results suggest that the four TCF/LEF paralog subfamilies in jawed vertebrates evolved through two rounds of whole-genome duplications. The TCF gene structure in jawless vertebrates resembles the ancestral vertebrate structure.

Summary: The study demonstrates that pharmacological inhibition of JNK signaling in cephalochordate embryos results in morphological abnormalities such as notochord elongation defects, cell delamination, and altered gene expression. This suggests a conserved role of JNK signaling in regulating cellular behavior and tissue differentiation during cephalochordate morphogenesis.

Summary: This study describes the three-dimensional distribution and fine structure of fibroblasts in the adult cephalochordate Asymmetron lucayanum using serial block-face scanning electron microscopy. The fibroblasts in the tail region were sparsely distributed, resembling vertebrate telocytes. They were involved in the production of nonfibrous components of the extracellular matrix through the release of dense material and secretion of granular material.

Summary: Aquatic single-cell organisms have long been thought to be the only primary producers of omega-3 long-chain polyunsaturated fatty acids (LC-PUFA). However, it has now been discovered that multiple invertebrates, including annelids, possess methyl-end desaturases that contribute to the production of LC-PUFA in the ocean. In this study, the front-end desaturase gene repertoire in annelids was examined, revealing at least two front-end desaturases with ω-5 and ω-6 ω-8 desaturase activities.
