Unerwünschte Erzählungen : zur Dialektik des Erzählens und Nicht-Erzählens im Engelsjahr

Große Erzählungen im Engelsjahr 2020 handeln von der Textilindustrie gestern und heute. Die vorliegenden kleinen Erzählungen spielen in anderen textilen Welten und jenseits der großen Fabriken. Von ihnen erzählt Friedrich Engels nicht. Dem Erzählten und Nicht-Erzählten auf der Spur finden wir schließlich heraus, dass auch zu Friedrich Engels selbst in einer bestimmten Weise erzählt - und nicht erzählt wird

Unerwünschte Erzählungen: zur Dialektik des Erzählens und Nicht-Erzählens im Engelsjahr

Große Erzählungen im Engelsjahr 2020 handeln von der Textilindustrie gestern und heute. Die vorliegenden kleinen Erzählungen spielen in anderen textilen Welten und jenseits der großen Fabriken. Von ihnen erzählt Friedrich Engels nicht. Dem Erzählten und Nicht-Erzählten auf der Spur finden wir schließlich heraus, dass auch zu Friedrich Engels selbst in einer bestimmten Weise erzählt - und nicht erzählt wird.Grand narratives in the "Engelsjahr" 2020 are about the textile industry yesterday and today. These little stories are set in other textile worlds and beyond the big factories. Friedrich Engels does not tell of them. Finally, following the track of the narrated and non-narrated, we discover that stories about Friedrich Engels himself are also told - and yet remain untold

The endophytic fungus Serendipita indica affects auxin distribution in Arabidopsis thaliana roots through alteration of auxin transport and conjugation to promote plant growth

21 Pág.Plants share their habitats with a multitude of different microbes. This close vicinity promoted the evolution of interorganismic interactions between plants and many different microorganisms that provide mutual growth benefits both to the plant and the microbial partner. The symbiosis of Arabidopsis thaliana with the beneficial root colonizing endophyte Serendipita indica represents a well-studied system. Colonization of Arabidopsis roots with S. indica promotes plant growth and stress tolerance of the host plant. However, until now, the molecular mechanism by which S. indica reprograms plant growth remains largely unknown. This study used comprehensive transcriptomics, metabolomics, reverse genetics, and life cell imaging to reveal the intricacies of auxin-related processes that affect root growth in the symbiosis between A. thaliana and S. indica. Our experiments revealed the sustained stimulation of auxin signalling in fungus infected Arabidopsis roots and disclosed the essential role of tightly controlled auxin conjugation in the plant-fungus interaction. It particularly highlighted the importance of two GRETCHEN HAGEN 3 (GH3) genes, GH3.5 and GH3.17, for the fungus infection-triggered stimulation of biomass production, thus broadening our knowledge about the function of GH3s in plants. Furthermore, we provide evidence for the transcriptional alteration of the PIN2 auxin transporter gene in roots of Arabidopsis seedlings infected with S. indica and demonstrate that this transcriptional adjustment affects auxin signalling in roots, which results in increased plant growth.We acknowledge financial support by the collaborative IPSC research project executed in the framework of the EIG CONCERT-Japan joint call on Food Crops and Biomass Production Technologies and the related national funding agencies: grant PCIN-2016–037 from the Ministry of Economy and Competitiveness (MINECO), Spain, to Stephan Pollmann and Jesús Vicente-Carbajosa; grants 01DR17007A and 01DR17007B from the Federal Ministry of Education and Research (BMBF), Germany, to Jutta Ludwig-Müller and Ralf Oelmüller, respectively; grant JPMJSC16C3 from the Japan Science and Technology Agency (JST) to Hitoshi Sakakibara; and grant EIG_JC1JAPAN-045 from the Centre National de la Recherche Scientifique (CNRS), France, to Anne Krapp. In addition, the project obtained financial support by grant PID2020-119441RB-I00 funded by MCIN/AEI/10.13039/501100011033 and, as appropriate, by “ERDF A way of making Europe,” by the “European Union” or by the “European Union NextGenerationEU/PRTR” to Stephan Pollmann.

Women leaders in the political field in Scotland:A socio-historical approach to the emergence of leaders

Drawing on a contextualised case, we present a specific approach to leadership studies that brings together history, sociology and politics. We start with the following event. In August 2015, the election of Kezia Dugdale as leader of the Labour Party meant that, for the first time the leaders of the three main political parties in the Scottish Parliament were women. We approach the study of this significant leadership event, first, through a critique of aspects of leadership studies as a field. We next consider the potential for socio-historical approaches in understanding this event. Then, as a contextualised example of this alternative approach to studying leadership, we apply Bourdieu’s theoretical concepts – in particular the political field – in order to historicise the conditions of possibility of this event. Finally, we consider issues of power and gender in relation to how the leaders position themselves in relation to their parties and to each other within the political field. In so doing, we contribute to critical leadership studies by developing and demonstrating a socio-historical approach that can help us to identify processes of organisation and change in relation to the emergence of leaders

Repeat turnover meets stable chromosomes: repetitive DNA sequences mark speciation and gene pool boundaries in sugar beet and wild beets

Schmidt N, Sielemann K, Breitenbach S, et al. Repeat turnover meets stable chromosomes: repetitive DNA sequences mark speciation and gene pool boundaries in sugar beet and wild beets. The Plant Journal. 2023;118(1):171-190.Sugar beet and its wild relatives share a base chromosome number of nine and similar chromosome morphologies. Yet, interspecific breeding is impeded by chromosome and sequence divergence that is still not fully understood. Since repetitive DNAs are among the fastest evolving parts of the genome, we investigated, if repeatome innovations and losses are linked to chromosomal differentiation and speciation. We traced genome and chromosome-wide evolution across 13 beet species comprising all sections of the genera Beta and Patellifolia. For this, we combined short and long read sequencing, flow cytometry, and cytogenetics to build a comprehensive framework that spans the complete scale from DNA to chromosome to genome. Genome sizes and repeat profiles reflect the separation into three gene pools with contrasting evolutionary patterns. Among all repeats, satellite DNAs harbor most genomic variability, leading to fundamentally different centromere architectures, ranging from chromosomal uniformity in Beta and Patellifolia to the formation of patchwork chromosomes in Corollinae/Nanae. We show that repetitive DNAs are causal for the genome expansions and contractions across the beet genera, providing insights into the genomic underpinnings of beet speciation. Satellite DNAs in particular vary considerably between beet genomes, leading to the evolution of distinct chromosomal setups in the three gene pools, likely contributing to the barriers in beet breeding. Thus, with their isokaryotypic chromosome sets, beet genomes present an ideal system for studying the link between repeats, genomic variability, and chromosomal differentiation and provide a theoretical fundament for understanding barriers in any crop breeding effort
