Speciesacuminata ssp. burmannica
Common NameCalcutta 4
AbbreviationCalcutta 4

The selected accession, named Calcutta 4 belongs to the subspecies of Musa acuminata burmannica native to south-east Asia. According to MusaPedia, the accession would have been grown at the Imperial College of Tropical Agriculture (ICTA) field collection in the West Indies from a sample of seeds received in 1931 from the Calcutta botanical garden. According to Ernest E. Cheesman, who was working at the ICTA at the time, the material originally came from Burma (today's Myanmar)

Calcutta 4 has been used extensively in breeding because of its resistance to black leaf streak. It is also resistant to sigatoka leaf spot, several races of Fusarium wilt and partially resistant to Radopholus similis and other nematodes

Calcutta 4 has also been often used to generate genomic resources such as ESTs, BAC libraries, BAC end sequencing etc.

The genome sequencing of this species is the result of the collaboration between Bioversity International and CIRAD. The project was technically supported by BGI and financially supported by the CGIAR Research Program on Roots, Tubers and Bananas (RTB).

The draft genome is released in early access before publication.

Restrictions on dataset usage

- I would like to use this data to help clone a gene, analyse a gene family, etc.

Please use this data to advance your studies. Please cite “M. acuminata calcutta 4 v1.0 – Banana Genome Hub http://banana-genome-hub.southgreen.fr/organism/Musa/acuminata-ssp-burmannica”

- I would like to do a large-scale comparison of Musa acuminata Calcutta 4 to other genomes, and/or a global analysis of its gene content.

Bioversity and CIRAD are making the completed Musa acuminata burminacoides 'calcutta 4' genome sequence available before scientific publication according to the Ft. Lauderdale Accord. This balances the imperative of Bioversity and CIRAD that the data be made available as soon and as completely as possible with the desire of contributing scientists and Bioversity and CIRAD to reserve a reasonable period of time to publish on the large scale genome sequencing and analysis without concerns about preemption by other groups.  By accessing these data, you agree not to publish any articles containing analyses of genes or genomic data on a whole genome or chromosome scale prior to publication by Bioversity or CIRAD of a comprehensive genome analysis.

Reserved Analyses
It includes the identification of complete (whole genome) sets of genomic features such as genes, gene families, pan genome, structural variations, repeat structures, GC content, or any other genome feature, and whole-genome- or chromosome- scale comparisons within Musa sp. or with other species.
The embargo on publication of Reserved Analyses by researchers outside of the Musa acuminata Calcutta 4 Genome Sequencing Project is expected to extend until the publication of the results of the sequencing project is accepted. Scientific users are free to publish papers dealing with specific genes or small sets of genes using the sequence data.

If these data are used for publication, the following acknowledgment should be included: 'These sequence data were produced by the Bioversity and CIRAD supported by the CGIAR Research Program on Roots, Tubers and Bananas'.
These data may be freely downloaded and used by all who respect the restrictions in the previous paragraphs. The assembly and sequence data should not be redistributed or repackaged without permission from the Bioversity and CIRAD.

We prefer that potential users of this sequence assembly contact the individuals listed under Contacts with their plans to ensure that proposed usage of sequence data are not considered Reserved Analyses.
