Genomic methods for identifying causative variants for trait loci applicable to a wide range of germplasm are required for plant biologists and breeders to understand the genetic control of trait variation.

We implemented Cas9-targeted sequencing for fine-mapping in apple, a method combining CRISPR-Cas9 targeted cleavage of a region of interest, followed by enrichment and long-read sequencing using the Oxford Nanopore Technology (ONT). We demonstrated the capability of this methodology to specifically cleave and enrich a plant genomic locus spanning 8kb. The repeated mini-satellite motif located upstream of the

transcription factor gene, causing red fruit colouration when present in a heterozygous state, was our exemplar to demonstrate the efficiency of this method it contains a genomic region with a long structural variant normally ignored by short-read sequencing technologiesCleavage specificity of the guide RNAs was demonstrated using polymerase chain reaction products, before using and resolve single-nucleotide and structural variants at the haplotype level in plant genomic regions. The combination of CRISPR-Cas9 target enrichment and ONT sequencing provides a more efficient technology for fine-mapping loci than genome-walking approaches.

In 2019, Kaya-Okur et al. reported on the cleavage under targets and tagmentation (CUT&Tag) technology for efficient profiling of epigenetically modified DNA fragments. It was used mainly for cultured cell lines and was especially effective for small samples and single cells. This strategy generated high-resolution and low-background-noise chromatin profiling data for epigenomic analysis. CUT&Tag is well suited to be used in plant cells, especially in tissues from which small samples are taken, such as ovules, anthers, and fibers.

Here, we present a CUT&Tag protocol step by step using plant nuclei. In this protocol, we quantified the nuclei that can be used in each CUT&Tag reaction, and compared the efficiency of CUT&Tag with chromatin immunoprecipitation with sequencing (ChIP-seq) in the leaves of cotton. A general workflow for the bioinformatic analysis of CUT&Tag is also provided. Results indicated that, compared with ChIP-seq, the CUT&Tag procedure was faster and showed a higher-resolution, lower-background signal than did ChIP.

A CUT&Tag protocol has been refined for plant cells using intact nuclei that have been isolated.

STEP involves four in-person individual sessions delivered during an inpatient psychiatric admission, followed by one month of weekly phone calls and daily text messages with mood monitoring and skills practice. A pilot randomized controlled trial of STEP vs. enhanced treatment as usual (ETAU) was conducted with 52 adolescents. Results indicated that on average 83% of sessions were completed and that on 70% of days, participants engaged with the text-messaging component of the intervention. Acceptability for both in-person and text-messaging components were also high, with satisfaction ratings averaging between good and excellent. STEP participants reported fewer suicide events than ETAU participants (6 vs. 13) after six months of follow-up.

Behaviour during hibernation contributes to energy conservation in winter. Hibernating bats select roosts with respect to physiological and environmental stressors, available local microclimate and species-specific requirements.

We found that, in the period between 1977 and 2018, hibernating

and

bats showed exponential population growth. The growth rates, corrected for local winter seasonal severity and winter duration, were equal to 10 and 13%, respectively. While

only utilised the thermally stable and, at survey time, warmer corridors in the hibernaculum, an increasing proportion of

roosted in the thermally stable corridors as their abundance increased. About 14% of all hibernating

displayed solitary roosting, irrespective of other covariates. Those bats that clustered together formed progressively larger clusters with increasing abundance, particularly in cold corridors. We found no statistically significant relationship for clustering behaviour or cluster size with winter severity or winter duration.

Abundance of hibernating bats is increasing in Central Europe. As the number of

bats increases, thermally unstable corridors become saturated with large clusters and the animals begin to roost deeper underground.

Initial laboratory findings revealed profound peripheral eosinophilia, and a chest computed tomography showed bi-apical consolidation. Bronchio-alveolar lavage demonstrated alveolar eosinophilia. She was diagnosed with idiopathic chronic eosinophilic pneumonia (ICEP). selleck inhibitor Her peripheral eosinophilia and respiratory symptoms improved rapidly with high-dose systemic corticosteroid therapy. However, she was intolerant to corticosteroid monotherapy due to non-compliance and psychological adverse effects. Mepolizumab was initiated as a steroid-sparing agent, resulting in successful therapy for 2 years without relapse or adverse effects. Mepolizumab is an interleukin-5 (IL-5) antagonist monoclonal antibody, which is a targeted therapy for diseases mediated by eosinophil activity and eosinophil proliferation. Mepolizumab is typically used in ICEP refractory to steroids, but this case supports its use in cases of glucocorticoid intolerance. Further study of IL-5 antagonist therapies for ICEP may identify an alternative treatment modality for patients in whom the adverse effects of corticosteroids pose a challenge.
