[Po-dev] Number of tissue and cell types

[Daniel Lang]

Hi,

sorry, if this is a bit off-topic. But after crawling the net and
literature unsuccessfully for quite some time now, I thought that you
might be the experts for this type of request:
For a phylogenetic analysis we are desperately looking for estimates of
the number of cell types and the number of different tissue types in the
gametophytic and sporophytic generations of the following angiosperms:
Arabidopsis lyrata
Arabidopsis thaliana
Carica papaya
Glycine max
Medicago truncatula
Populus trichocarpa
Ricinus communis
Vitis vinifera
Oryza sativa
Sorghum bicolor
Zea mays (current estimate: total 100 cell types)

I've already tried to extract part of this data using the
plant_structure associations from the database dump, but I am unsure
whether the annotations are comprehensive enough to give a reliable answer?
PO term associations including transitive indirect annotations:
Arabidopsis thaliana    gametophyte     10
Arabidopsis thaliana    sporophyte      229
Oryza sativa    gametophyte     4
Oryza sativa    sporophyte      145
Zea mays        gametophyte     2
Zea mays        sporophyte      42


I would be excited to hear your estimates/data on this! Do you know of
any web resources, literature or databases that would help us answer
these questions?

To conserve the data for future use, I will post the numbers to
BioNumbers (http://bionumbers.hms.harvard.edu).

Thank you very much in advance!

Daniel
