| Title |
Gametophyte sample 4 (Cy3) vs. Mid-sporophyte sample 1 (Cy5) |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
Gametophytic protonemal tissue of Physcomitrella patens sample 4
|
| Organism |
Physcomitrium patens |
| Characteristics |
ecotype: Villesexel
tissue: 7 day old protonemal tissue
|
| Biomaterial provider |
Caspar Chater
|
| Treatment protocol |
No treatment was used
|
| Growth protocol |
Plants were grown in Sanyo MLR incubators with a 16-hour photoperiod (140 µmol m 2), 22°C day temperature and 16°C night temperature. Protonema and gametophores were grown on organic-nitrogen-supplemented BCD medium in sterile petri dishes overlaid with sterile cellophane discs and sealed with micropore tape, as described (Knight et al, 2002).
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was extracted from all plant tissues using the Spectrum Total Plant RNA extraction kit (Sigma, STRN250) following manufacturer’s recommendations. Approximately 100mg of tissue was harvested directly into liquid nitrogen in microcentrifuge tubes and ground to a powder. RNA integrity and concentration were analysed by agarose gel electrophoresis and an Agilent Bioanalyzer. Gametophyte RNA was extracted from seven day old protomenal tissue.

| Label |
Cy3
|
| Label protocol |
Samples were co-hybridised as total RNA with Cyanine (Cy-3) fluorescent ULS labels MOgene LC, an Agilent certified facility based in St Louis, MO, USA (www.mogene.com, MOGene LC, St. Louis)

|
| Channel 2 |
| Source name |
Mid-sporophytic tissue of Physcomitrella patens sample 1
|
| Organism |
Physcomitrium patens |
| Characteristics |
ecotype: Villesexel
tissue: Mid-sporophytic tissue (defined as ovoid to near-spherical translucent green capsules with the foot, calyptras and calyptral remnants removed)
|
| Biomaterial provider |
Caspar Chater
|
| Treatment protocol |
Gametogenesis was initiated by transferring cultures to 15°C growth cabinet for three weeks with a 16-hour photoperiod (140 µmol m 2), after which they were flooded with sterile deionised water to promote fertilization of archegonia for about 2 hours. Subsequently the cultures were returned to gametophyte growth conditions for further development of the sporophytes.

Plants were grown in Sanyo MLR incubators with a 16-hour photoperiod (140 µmol m 2), 22°C day temperature and 16°C night temperature. Protonema and gametophores were grown on organic-nitrogen-supplemented BCD medium in sterile petri dishes overlaid with sterile cellophane discs and sealed with micropore tape, as described (Knight et al, 2002). Gametophore production was initiated by sub-culturing protonemal fragments onto agar lacking cellophane discs and culturing these for longer than 14 days.
