Seasonal high-frequency measurements of discharge, water temperature, and specific conductivity from Canada Stream at F1, McMurdo Dry Valleys, Antarctica (1990-2023, ongoing)
As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor the glacial meltwater streams in this region. This package contains data pertaining to continuous monitored water quality and quantity parameters measured with automatic recording devices on streams in this region. Specifically, this metadata record describes the hydrology data set for the McMurdo Dry Valleys' Canada Stream at the F1 streamgage, located in the Fryxell Basin of Taylor Valley. Measurements commenced during the 1990-91 season and are ongoing. This dataset extends through the first half of the 2022-23 field season.
Daily summarized seasonal measurements of discharge, water temperature, and specific conductivity from Canada Stream at F1, McMurdo Dry Valleys, Antarctica (1990-2023, ongoing)
As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor the glacial meltwater streams in that region. This package contains daily summaries derived from 15-minute measurements of water quality and quantity parameters measured with automatic recording devices on streams in this region. Specifically, this metadata record describes the daily hydrological summaries for the McMurdo Dry Valley's Canada Stream at F1, located in the Fryxell Basin of Taylor Valley. Measurements commenced during the 1990-91 austral summer and are ongoing. This dataset extends through the first half of the 2022-23 field season.
Quartet of familiar females – 16p11.2 Del mouse strain – 2 WT + 2 Del/+ - F1
<p>We monitored the individual and social behaviours of each quartet of mice over three days and nights in the Live Mouse Tracker system (LMT, plugin 931; de Chaumont et al. 2019 Nat. Biomed. Engin.). This system tracks individually mice living in a group over several days and nights and extracts automatically the number, total duration and mean duration of more than thirty behavioural events describing the posture of the mouse, the types of social contacts, the dynamic social approach and escapes and complex social groupings (see de Chaumont et al. 2019 Nat. Biomed. Engin.). In this system, the four mice (10-14 weeks of age; 2 WT mice and 2 Del/+ mice) from the same housing cage (housed together from weaning on) were left undisturbed for 71 hours in a large transparent Plexiglas cage (50 x 50 x 40 cm), with fresh bedding, a house (width: 100 mm, depth: 75 mm, height: 40 mm) in red Plexiglas, 6 dental cotton rolls as well as food and water ad libitum. Light/dark cycle and temperature conditions were similar to those of the housing room (12/12h light/dark, lights on at 07:00 AM, 100 lux when the lights were on). Each recording session started between 03:00 and 04:00 PM. At the end of the session, mice were placed back in their home cage and the LMT setup was cleaned with soap water and dried with paper towels. The upload includes the sqlite database from LMT (processed).</p>

Data from: Drastic shift in flowering phenology of F1 hybrids explains the population structure of Imperata cylindrica in Japan
<p>Hybridization is a major source of phenotypic variation and a driving force for evolution. On the other hand, these novel traits can often disrupt adaptive relationships between the parental phenotypes and their environments. However, it remains unclear how new hybrid traits disrupt local adaptation. Here, we report how a new phenotype of hybrids between two ecotypes of Imperata cylindrica contributes to rapid reproductive isolation from their parents and affects hybrid fitness.</p> <p>We analyzed 350 accessions of I. cylindrica collected from the 1980s to the 2010s throughout Japan to explore the genetic population structure of the hybrids. We surveyed flowering periods, seed sets, and germination of two ecotypes and their hybrids in both natural habitats and common gardens.</p> <p>Genetic analyses of population structure revealed that the hybrid populations consisted of only F1 individuals, without post-F1 hybrids. The flowering phenology of the F1 plants was delayed to autumn, 5–6 months later than the parental ecotypes.</p> <p>The drastic shift in flowering phenology prevents F1s from backcrossing. In addition, it changes their seed dispersal time to winter. Germination is inhibited by low temperatures, and the seeds likely decay before the next spring, resulting in the absence of an F2 generation. For the first time in the field, we found environmental mismatch of F1 as a specific mechanism for the maintenance of only F1 populations.</p> <p>Synthesis. We have demonstrated that this flowering phenology mismatch promotes reproductive isolation between the parents and F1s and affects various temporal components of the hybrids, resulting in a unique hybrid population consisting only of F1s. This system sheds light on the importance of hybrid traits in terms of rapid reproductive isolation.</p>

F1 Maize Iso-Seq - Final & Intermediate files
<p>===============================================================================</p> <p>Variant Phasing and Haplotypic Expression from Single-molecule Sequencing in Maize</p> <p>===============================================================================</p> <p>Maize is a diploid species with very high genetic diversity. Haplotype phasing of genetic variants in maize is important for interpretation of the genome, population genetic and functional genomic analysis of allelic activity. However, due to splicing variability and sequencing length limitation, phasing at isoform level are always very challenge. Here, we developed a tool called ‘Iso-Phase’ to phase the isoforms in hybrids and present the first isoforms phasing study in maize using inbred lines B73 and Ki11, as well as their reciprocal crosses from full-length single-molecule sequencing. Our results show that maize parental lines and hybrid lines display different splicing activity, and 6,847 genes can be phased through Iso-Phase in two reciprocal hybrids using embryo, endosperm and root tissues. We identified parental origin isoforms in maize hybrids, different novel isoforms between maize parent and hybrid lines, provides measures of haplotypic expression that increase power and accuracy in studies of allelic expression. It is the first study of phased full-length isoforms in maize, as well as in plants, which provides insights about maize and plant heterosis at allele-specific full-length transcriptional level. The approach used in this study also provide important information for many other phasing studies in different species. </p>
