Stacks of microCT Scans, Cell size, weight, volume and thallus size data supporting the paper 'Mechanical regulation of tissue flatness in Marchantia'

These data are the supporting elements to the following paper: 'Mechanical regulation of tissue flatness in Marchantia'

 .tif files contain MicroCT (MCT) scans of 16-day-old Marchantia polymorpha thalli. Three genotypes were analysed here: fer-2 mutant (from Mecchia et al., 2022), FER-OE #9 (proMpEF1::MpFERONIA-mCitrine trangenic line 9) from Mecchia et al., 2022), and Tak-1 (WT line). These plants were grown in 3 different media: Gamborgh B5 + vitamins and 0.6, 1.2 and 2.5% agar, and one stress condition consisting of the adjunction of a thin PDMS film at 4, to mimich external mechanical stimulus (only performed on thalli grown on 1.2% agar).

MicroCT scans were performed at the faculity of odontology of Université Paris-Cité (Plateform imagerie du vivant) with the technical support of Lotfi Slimani and Baptiste Casel. https://piv.u-paris.fr/micro-ct-haute-resolution/ 

All files already have embeded scales.

Each file name consists of a unique ID number in the following form:

P++-

-LETTER: One letter = one imaging session

-NUMBER: Individual and Genotype: 33-40 -> Tak1; 200-207->fer-2; 41-49 -> FER-OE

-CONDITION : AGAR0.6/AGAR2.5/PDMS. Absence of condition indicates growth on standard medium (1.2% agar). PDMS indicated growth on standard medium and supplementation of a topping PDMS film at day 4)

-Volume data were calculated from MicroCT scans

-thallus projected surfaces were calculated from MicroCT scans

-Lambda curvature calculation.ipynb is suited for MorphographX mesh exported .txt files.
