Dear MGIS Users,
Originally planned on December 2021, we provide this update in January 2022 that fix a few issues on data loading. Please see below the updates and new features for the MGIS website.
Data update
ITC collection
A total of 58 new accessions have been introduced at ITC in 2021. This material comes from different countries:
- Papua New Guinea 33 accessions
- Cook Islands 13 acessions
- Samoa 10 accessions
- China 1 accession
- Indonesia 1 accession
Accessions from Cook islands, Samoa and 1 accession from Papua New Guinea are accessions collected by Julie Sardos with the supports of:
- the Ministry of Agriculture and Fisheries of Samoa (MAF) and the Pacific Community (2019),
- the Ministry of Agriculture of the Cook Islands with support of the Pacific Community (SPC) (2019),
- and the NARI National Agricultural Research Institute of Papua New Guinea (2016).
Evaluation data
We have started to extract values from publications using ITC accessions in order to insert them into the database. In parallel to this data mining an interface for searching through this new dataset is made available in the filters of the accession search page.
If you click on the evaluation traits yellow button a new window will display the list of descriptors or specific contents evaluated in phenotypic studies. This is an on going work and more data will be added to MGIS along the years.
In the example below the first tab lists the descriptors associated to agronomic evaluation.
If you want to see other traits then the classical one from the descriptors booklet then select the Other tab. Currently several Pro vitamin A contents with values are listed.
Musa In Situ
The interface is accessible from here.
The home page presents a list of observations imported from iNaturalist and other sources.
• On the right-hand side of the page, filters allow the display to be focused according to geographical and taxonomic criteria.
• At the top of the page, a button allows you to switch to the same display as a map.
• At the top of the page, a special box allows a user from iNaturalist to locate the observation(s) of which he/she is the author.
• The hover over each point on the map provides access to a summary of the information for that point.
• For each observation, a record is generated, directly accessible. This page contains information from the iNaturalist observation, as well as pictures of the plant.
In the current version of MusaInSitu, country filters and taxonomic filters are now additive.
Therefore, it is possible to display, for instance, the data points corresponding to two different species on the same map and compare their distributions.
Publications associated to individual accessions
We mapped the following scientific papers to genebank accessions:
- Organelle DNA sequence data provide new insights into the maternal and paternal lineages of Musa species germplasms
- Agronomic performance of provitamin A-rich banana cultivars in Burundi and the Democratic Republic of Congo
- Reassessing Banana Phylogeny and Organelle Inheritance Modes Using Genome Skimming Data
- The impact of slow stomatalkinetics on photosynthesis and water use efficiency under fluctuant light
- Sources of resistance to Pseudocercospora fijiensis, the cause of black Sigatoka in banana
- Assessment of genetic diversity of Musa species accessions with variable genomes using ISSR and SCoT markers
- Genetic Diversity and Population Assessment of Musa L. (Musaceae) Employing CDDP Markers
- Genome ancestry mosaics reveal multiple and cryptic contributors to cultivated banana (updated)
Accession Page changes
The passport data page loads in a lighter way in order to improve the response time (which is not yet as fast as we would like). So now under the Passport data information, there is an alignement of buttons to unload/load the corresponding information.
Maps
As noticed in the screenshot above the Map contains now more information.
Molecular characterization
As a follow up of publications by Martin et al, 2020 and Cenci et al, 2021, we have now included information about chromosome structure of the accessions charaterized in the ITC, CIRAD and CARBAP collections. The number of accessions covered is expected to increase in the coming years.
As mentioned in a previous news, supporting dataset for this type of analyses is available through Gigwa on the MGIS website.
Finally, in our 2021 March update, we wrote a few words on a new version of the MGIS web site. We must admit that the expected new version (i.e. V5) did not move as fast as expected. The current version with the addition of the features for searching on few specific evaluation traits can be seen as an intermediate version (i.e. V4.5) that allows us to work on how best search and display evaluation data of an accession.
We wish you a healthy and happy 2022 year.
Let's continue to enrich MGIS with new data and features in order to help you in your research on Musa and to facilitate the use of this germplasm.
