02 P.patens sexual development


RNA-seq expression data of P. patens experiments conducted in sexual organs and first stages of the sporophyte development. All samples were normalized to RPKM.
The experiments of this dataset were published in Genau et al., 2021 (Gametophore apices), Meyberg et al., 2020 (antheridia 21 DAI), Julca et al., 2021 (Gransden antheridia development, sperm cell packages, mature archegonia and Granden sporophyte development), Haas et al., 2020 (Laser Capture Microdissection of egg cell and E0 embryo together with venter cells of their corresponding unfertilized and fertilized archegonia. Also Bulk RNAseq of ES1), Szövényi et al., 2017 (E0/E1/E2, ES/ES1, green sporophyte premeiotic).

Due to the small tissue size all samples but the gametophore apices required PCR amplification. For more information about RNA-seq extraction, amplification and mapped reads see the file sample_information.xlsx.

Experimental Conditions (3 replicates unless otherwise noted):

Re: Reute WT
Gd: Gransden WT
Vx: Villersexel WT
DAI: days after induction
DAF: days after fecundation
2 DAW: 2 days after watering
Note: Gametophores apices were collected to study gene expression in sexual organs.

01 C.braunii nodal cells

Vegetative Chara braunii S276 cultures were kept at 22°C in a 16 h light: 8 h dark cycle with white light lateral illumination (30–70 μmol photons m−2 s−1). Nodal cells were cut out and pooled from several algae and total RNA extracted from both pooled nodal cells and a whole thallus. Poly(a)+ selected cDNA libraries were generated via service and sequenced on an Illumina NextSeq 500 system using 75 bp read length. Data analysis was performed on the European instance galaxy server: reads were trimmed via cutadapt, mapped and counting of reads was performed using RNA STAR.
Samples are based into one replicate normalized to TPM.

Figure on right: Specimen of Chara baunii. Detailed view of Chara braunii S276. Shown is the area with the interior node cells confined by two internodal cells. Nodal cells pinched off peripheric cells from which branchlets developed with a structure analogous to the main stem consisting of branchlet nodal and internodal cells. Branchlet nodal cells are the origin for the development of antheridia (shown) and the typical charophytic oogonia after proliferation.



02 C.braunii response to salinity

Vegetative Chara braunii S276 cultures were pre-cultivated at 21°C with a light intensity of 50–60 μmol photons m−2 s−1 under a 16 h light: 8 h dark cycle. To evaluate osmoregulatory ability, the alga was then incubated for 6, 24, and 48 h at an elevated salinity of 5 PSU sea salt and whole thalli without the rhizome were harvested. Poly(a)+ selected cDNA libraries were generated via service using the Illumina TruSeq stranded protocol and paired-end sequenced using 2x100 bp read length. Data analysis was performed on the European instance galaxy server: reads were trimmed via cutadapt, mapped and counting of reads was performed using RNA STAR and time series gene expression analysis was performed using DESeq2.
Samples are based into two replicates normalized to TPM.

03 C.braunii carbon media

Vegetative Chara braunii S276 cultures were cultivated at 21°C with a light intensity of 50-60 μmol photons m−2 s−1 under a 16 h light: 8 h dark cycle. Cultivation under ambient air conditions (0.04% CO2) was defined as a low-inorganic carbon (LC) condition. To evaluate response to fluctuating inorganic carbon conditions, medium of the algae (LC) was exchanged with high-inorganic carbon medium (HC, 10 mM NaHCO3). Both HC and LC algae were acclimated for 7 d, after which the liquid medium was exchanged with the respective other (HC to LC and LC to HC) and thalli samples sans rhizome collected 24 and 48h after the shift. Poly(a)+ selected cDNA libraries were generated via service using the Illumina TruSeq stranded protocol and paired-end sequenced using 2x100 bp read length. Data analysis was performed on the European instance galaxy server: reads were trimmed via cutadapt, mapped and counting of reads was performed using RNA STAR and time series gene expression analysis (HC to LC and LC to HC) was performed using DESeq2.
Samples are based into two replicates normalized to ???.
