In this study, we report the 5' and 3' RNA extremities and promoters of five mitochondrial genes, atp1, atp4, atp6, atp9, and cox3. The results reveal that four genes (atp1, atp4, atp6, and cox3) are transcribed from multiple initiation sites but with a uniform transcript at the 3' end, indicating that heterogeneity of the 5' end is a common feature in the transcription of kenaf mitochondrial genes. Furthermore, we found that the transcription initiation sites of these four genes are significantly different in UG93A, UG93B, and the F1 hybrid. These data indicate that nuclear loci and unknown transcription factors within the mitochondria of different cytoplasmic types may be involved in mitochondrial transcription. Promoter architecture analysis showed that the promoter core sequences are conserved in the kenaf mitochondrial genome but are highly divergent, suggesting that these elements are essential for the promoter activity of mitochondrial genes in kenaf. Our results reveal that the heterogeneity of the 5' end and uniformity at the 3' end are common transcriptional features of mitochondrial genes. These data provide essential information for understanding the transcription of mitochondrial genes in kenaf and can be used as a reference for other plants.","PeriodicalId":50588,"journal":{"name":"Development Genes and Evolution","volume":"231 5-6","pages":"119-130"},"PeriodicalIF":2.4,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39684941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gene expression data and the re-interpretation of early transitional fossils have supported the homology of the deutocerebrum and its associated appendages, implying a homology between primary antennae (mandibulates), chelicerae (euchelicerates), and chelifores (sea spiders). Nevertheless, comparatively little is known about the mechanistic basis of proximo-distal (PD) axis induction in chelicerates, much less the basis for cheliceral fate specification. Here, we describe a new cheliceral teratology in the spider Tetragnatha versicolor Walckenaer, 1841, which consists on a duplication of the PD axis of the left chelicera associated with a terminal secondary schistomely on the fang of the lower axis. This duplication offers clues as to potential shared mechanisms of PD axis formation in the chelicera. We review the state of knowledge on PD axis induction mechanisms in arthropods and identify elements of gene regulatory networks that are key for future functional experiments of appendage development in non-insect model systems. Such investigations would allow a better understanding of PD axis induction of modified and poorly studied arthropod limbs (e.g., chelicerae, chelifores, and ovigers).","PeriodicalId":50588,"journal":{"name":"Development Genes and Evolution","volume":"231 5-6","pages":"131-139"},"PeriodicalIF":2.4,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00427-021-00678-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39012251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, functional analysis has revealed germins and GLPs are involved in diverse processes such as embryonic development and stress responses. The aim of this study was the analysis of barley germins and GLPs. In this study, 80 putative germins and GLPs have been identified in barley by using known 17 germins and GLP sequences. Analysis of germins and GLPs showed all germins and GLPs are distributed on all seven chromosomes that most of them spread through chromosome 3, 4 and 7 with 16, 18 and 12 proteins on each, respectively. The protein sizes varied between 185 and 335 amino acids, with an average length of 225 aa. Twelve conserved motifs were found. While germin motifs 1 and 3 were detected in all germins and GLPs, some motifs were found to be related to signalization. Interestingly, protein-protein interaction analysis demonstrated some GLPs are associated with RAB6-interacting golgin, oligopeptide transmembrane transporter activity, beta-glucuronidase activity, protein N-linked glycosylation, multi-pass membrane protein, and proteins containing zinc finger (Znf) domain and RING (really interesting new gene)-type zinc finger domains. Our findings suggest that barley germins and GLPs may have diverse functions that make them important candidates for crop improvement.","PeriodicalId":50588,"journal":{"name":"Development Genes and Evolution","volume":"231 5-6","pages":"109-118"},"PeriodicalIF":2.4,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39287510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the chick, experimentally proven activity of signalling molecules and transcription factors lead to the concept of a 'global positioning system' for initial axis formation whereas in the (mammotypical) rabbit embryo, a series of morphological or molecular domains are part of a putative 'three-anchor-point model'. Because circular expression patterns of genes involved in axis formation exist in both amniote groups prior to, and during, gastrulation and may thus be suited to reconcile these models, the expression patterns of selected genes known in the chick, namely the ones coding for the transcription factors eomes and tbx6, the signalling molecule wnt3 and the wnt inhibitor pkdcc, were analysed in the rabbit embryonic disc using in situ hybridisation and placing emphasis on their germ layer location. Peripheral wnt3 and eomes expression in all layers is found initially to be complementary to central pkdcc expression in the hypoblast during early axis formation. Pkdcc then appears - together with a posterior-anterior gradient in wnt3 and eomes domains - in the epiblast posteriorly before the emerging primitive streak is marked by pkdcc and tbx6 at its anterior and posterior extremities, respectively. Conserved circular expression patterns deduced from some of this data may point to shared mechanisms in amniote axis formation while the reshaping of localised gene expression patterns is discussed as part of the 'three-anchor-point model' for establishing the mammalian body plan.","PeriodicalId":50588,"journal":{"name":"Development Genes and Evolution","volume":"231 3-4","pages":"73-83"},"PeriodicalIF":2.4,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00427-021-00677-w","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39004244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used different imaging methods and measured different external morphological structures to detect possible ontogenetic changes. One structure exhibiting post-embryonic changes is the chelicera. Here the significant change occurs between the last immature stage and the adult, yet only in males. For the spinnerets, we could not detect ontogenetic changes, but instead a high variability in length and width, probably due to their lack of pivot joints between the elements. The strongest morphological change during ontogeny occurred on the sternum, which begins with a rather roundish shape in the first stage and changes to being fairly elongate in shape in the last immature stages and the adult. This specific sternum shape only occurs in adults of mesothelan spiders, while opisthothelan spiders have a broader sternum also in the adult.

We report a previously uncharacterized significant sequence divergence of a highly conserved hindbrain hoxa2b enhancer element in the family syngnathidae (pipefishes, seahorses, pipehorses, seadragons). We compared the hox cis-regulatory element variation in the Gulf pipefish and two species of seahorse against eight other species of fish, as well as human and mouse. We annotated the hoxa2b enhancer element binding sites across three species of seahorse, four species of pipefish, and one species of ghost pipefish. Finally, we performed in situ hybridization analysis of hoxa2b expression in Gulf pipefish embryos. We found that all syngnathid fish examined share a modified rhombomere 4 hoxa2b enhancer element, despite the fact that this element has been found to be highly conserved across all vertebrates examined previously. Binding element sequence motifs and spacing between binding elements have been modified for the hoxa2b enhancer in several species of pipefish and seahorse, and that the loss of the Prep/Meis binding site and further space shortening happened after ghost pipefish split from the rest of the syngnathid clade. We showed that expression of this gene in rhombomere 4 is lower relative to the surrounding rhombomeres in developing Gulf pipefish embryos, reflecting previously published functional tests for this enhancer. Our findings highlight the benefits of studying highly derived, diverse taxa for understanding of gene regulatory evolution and support the hypothesis that natural mutations can occur in deeply conserved pathways in ways potentially related to phenotypic diversity.","PeriodicalId":50588,"journal":{"name":"Development Genes and Evolution","volume":"231 3-4","pages":"57-71"},"PeriodicalIF":2.4,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00427-021-00676-x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38994384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the molecular interactions that regulate the process of egg formation, key for the reproductive cycle of the vector, is still largely unknown. In order to understand the molecular and cellular basis of the oogenesis, we examined the function of the gene Bicaudal C (BicC) during oogenesis and early development of R. prolixus. We show that R. prolixus BicC (Rp-BicC) gene is expressed in the germarium, with cytoplasmic distribution, as well as in the follicular epithelium of the developing oocytes. RNAi silencing of Rp-BicC resulted in sterile females that lay few, small, non-viable eggs. The ovaries are reduced in size and show a disarray of the follicular epithelium. This indicates that Rp-BicC has a central role in the regulation of oogenesis. Although the follicular cells are able to form the chorion, the uptake of vitelline by the oocytes is compromised. We show evidence that the polarity of the follicular epithelium and the endocytic pathway, which are crucial for the proper yolk deposition, are affected. This study provides insights into the molecular mechanisms underlying oocyte development and show that Rp-BicC is important for de developmental of the egg and, therefore, a key player in the reproduction of this insect.","PeriodicalId":50588,"journal":{"name":"Development Genes and Evolution","volume":"231 1-2","pages":"33-45"},"PeriodicalIF":2.4,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00427-021-00673-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25475826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
