Over the past two decades evidence to support this point of view has grown with new data from space probes and space exploration. In this article we argue that microorganisms are likely to be widely present in the clouds of Venus, and may under certain conditions have a ready route to Earth. Such transfers could occur by the action of the solar wind that leads to expulsion of parts of the atmosphere laden with microorganisms. The expelled material forms a comet-like tail in the antisolar direction and during inferior conjunctions of Venus could lead to injections of bacteria and other microorganisms onto the Earth. In situations of very low sunspot activity as now prevails, with a consequent weakening of the magnetopause this flux of microbes will be considerably enhanced. The inferior conjunction of 4 June 2020 together with the prevailing deep minimum in the sunspot cycle provides a combination of circumstances that is particularly favorable to such a process.</p>","PeriodicalId":50949,"journal":{"name":"Advances in Genetics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/bs.adgen.2020.06.004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38509957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this chapter, we review the 44 cases of CDK13-related disorder reported to date, highlighting key clinical pointers to this diagnosis including characteristic craniofacial features, feeding difficulties in infancy, and the presence of structural heart or brain malformations. The spectrum of reported mutations is also described, demonstrating an excess of missense mutations arising in the protein kinase domain. Exploration of genotype-phenotype correlations suggests a trend toward milder phenotypes in patients with mutations predicted to cause haploinsufficiency of CDK13, while missense mutations affecting amino acid residue 842 appear most likely to be associated with structural malformations. The greater phenotypic impact of missense variants is hypothesized to occur due to a dominant-negative mechanism, by which the mutant protein acts to sequester cyclin K in inactive complexes. Functional studies to validate this hypothesis have not yet been carried out, however. Differential diagnosis and recommendations for clinical care of patients with CDK13-related disorder are also described, emphasizing baseline echocardiography, vigilance for feeding and swallowing difficulties, and regular developmental evaluation as key components of care. Finally, future directions for CDK13 research are discussed, including the need to resolve uncertainty regarding pathogenicity of CDK13 haploinsufficiency, and to gather further longitudinal data from large cohorts in order to inform the clinical care of patients with this diagnosis.</p>","PeriodicalId":50949,"journal":{"name":"Advances in Genetics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/bs.adgen.2018.11.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37084327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little or no research attention is given toward neglected and underutilized crop species (NUCS) which hold the potential to ensure food and nutritional security among the ever-growing global population. NUCS are predominantly climate resilient, but their yield and quality are compromised due to selective breeding. In this context, the importance of omics technologies namely genomics, transcriptomics, proteomics, phenomics and ionomics in delineating the complex molecular machinery governing growth, development and stress responses of NUCS is underlined. However, gaining insights through individual omics approaches will not be sufficient to address the research questions, whereas integrating these technologies could be an effective strategy to decipher the gene function, genome structures, biological pathways, metabolic and regulatory networks underlying complex traits. Given this, the chapter enlists the importance of NUCS in food and nutritional security and provides an overview of deploying omics approaches to study the NUCS. Also, the chapter enumerates the status of crop improvement programs in NUCS and suggests implementing \"integrating omics\" for gaining a better understanding of crops' response to abiotic and biotic stresses.</p>","PeriodicalId":50949,"journal":{"name":"Advances in Genetics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/bs.adgen.2019.01.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37084325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
