maize cytogenetic band data

edoardobertolini opened this issue · comments

Hello Eric,
Could you please share the cytogenetic band data for the species Zea mays (corn). I cannot retrieve the data from Genomaize.
Thanks!
Edo

Sure! Cytogenetic band data for maize is in zea-mays.json.

Relevant upstream files include genomaize.py and zea-mays-b73-v2-centromeres.tsv. Ideogram added cytogenetic band data for maize in 2017, via #87.

If more would help, please let me know.

Much appreciated, Edo. Any chance you could open a PR with that data?

cytogenetic band coordinates are from the maize assembly AGPv4 and that the centromere coordinates are from the assembly AGPv2. Is this correct?

Not quite. Bands and centromeres are both from AGPv2. (See next comment for clarifications.)

More specifically, bands and centromeres are from zeaMay_b73_v2 in Genomaize, which per MaizeGDB is also known as AGPv2, formally B73 RefGen_v2 (GCA_000005005.4).

I'll keep this issue open for a week or so, in case you can open a PR with your UCSC-formatted data.

(Below is adapted from an email I sent. I surface it here for any future curious maize researchers.)

Investigating deeper, I see my previous comment has an error. Ideogram.js data for Zea mays (maize, corn) centromeres is indeed from Genomaize [1], but its "bands" are from Ensembl [2]. Specifically, the maize cytobands came from Ensembl's public MySQL database zea_mays_core_35_88_7. That database no longer exists, but an earlier archive shows a "bands" column in a "karyotype" table. Detailed steps to reproduce, and full raw output, are shown below in [3].

You can also access similar data more simply, at ftp://ftp.ensemblgenomes.org/pub/plants/release-25/mysql/zea_mays_core_25_78_6/karyotype.txt.gz. That link comes by way of https://www.biostars.org/p/240614/. It's unfortunate that such data is not available for new assembly versions; I suspect it was deprioritized due to lack a way for Ensembl to visualize the data. Ideogram.js is the only resource I know that shows maize centromeres and bands (https://eweitz.github.io/ideogram/eukaryotes?org=zea-mays).

The experimental origin of such band data would certainly help to know. I see a 1985 paper notes "different classes of maize heterochromatin can be differentiated through C-banding" [4].

The paper discusses knobs and other heterochromatin patterns -- perhaps the Ensembl "bands" represent the latter?
