Activation of LINE-1 after fertilisation regulates global chromatin accessibility

Project description:Upon fertilisation, the highly differentiated gametes reprogram to a totipotent state to initiate a new developmental programme. Approximately half of the mammalian genome is composed of repetitive elements, including retrotransposons, some of which are transcriptionally activated after fertilisation. It is generally assumed that retrotransposons become activated as a side-effect of the large chromatin remodelling underlying the epigenetic reprogramming of the gametes. Here, we have used a targeted epigenomic approach to address whether specific families of retrotransposons play a direct role in chromatin organisation and developmental progression after fertilisation. Using this approach, we demonstrate that precocious silencing of LINE-1 reduces chromatin accessibility, while their prolonged activation prevents gradual chromatin compaction, natural to developmental progression. Preventing LINE-1 activation and interfering with their silencing results in a reduced developmental rate independently of the coding nature of the LINE-1 transcript, suggesting that LINE-1 functions primarily at the chromatin level. Our data suggest that activation of LINE-1 regulates global chromatin accessibility at the beginning of development and indicate that activation of retrotransposons is an integral part of the developmental programme.

Characterising the effect of crop species and fertilisation treatment on root fungal communities.

Project description:Information about the root mycobiome may improve the overall quality of the plants and contribute to a valuable strategy to enhance sustainable agriculture. Therefore, we assessed differences in fungal community diversity and composition in the roots of potato, wheat and barley grown under mineral nitrogen fertilisation at five rates, with and without farmyard manure amendment. The same factorial combination of treatments has been used since 1989. Species richness and diversity, as well as community composition, of different fungal guilds were characterised using Illumina MiSeq sequencing of the ITS2 region. Crop species was the main factor determining overall fungal richness and diversity, with wheat showing the highest, and potato the lowest, richness and diversity. Pathogen diversity indices were highest in wheat plots amended with farmyard manure, whereas the lowest values were observed for potato roots. Fertilisation treatments and the interaction between crop species and fertilisation had the strongest impact on arbuscular mycorrhiza and saprotroph diversity. Crop species also determined the composition of the overall fungal community and that of fungal guilds, whereas fertilisation treatment had only a minor effect. This study highlights crop species as the main driver in shaping root fungal diversity and composition under the same environmental conditions.

A combination of organic acids and glucose prime a late stage of fungal biotrophy

Project description:We show that combinations of organic acids and glucose trigger phenotypes associated with the late stage of biotrophy for the maize pathogen Ustilago maydis. These phenotypes include the expression of a set of effectors normally observed only during biotrophic development as well as the formation of melanin associated with sporulation in plant tumors.

Bulk RNA-seq dataset of uninjured vs injured larval zebrafish hearts at 48 hours post injury on 5 days post fertilisation

Project description:This experiment sought to understand the transcriptomic changes that occur in the larval zebrafish heart following injury. 600 hearts were laser injured at 3 days post fertilisation, extracted 48 hours later and pooled into three groups of 200. RNA was extracted from the whole heart(s) and sent for sequencing along with 3 groups of 200 uninjured hearts, extracted and processed identically. RNA sequencing, quality control and alignment was performed by the commercial company GENEWIZ.
