We investigated the total lipid fatty acid (FA) composition of the fern Asplenium scolopendrium gametophyte, representing 25 individual FA species, for the first time. Conjugated octadecadienoates-18:2(10,12), rarely found in plant tissues-were identified. The possibility of modulating the lipid FAs composition under the action of light of different wavelengths on in vitro cultured gametophytes was demonstrated.

The experiment involved weekly applications of 10 μmol of AgNPs for 15 weeks in a greenhouse over a summer period. A comprehensive characterization of the AgNPs was performed via TEM, ESI/EELS, and zeta potential measurements before and throughout the experiment.

Cutinsomes, which are electron-dense structures of spherical shape, have been identified by transmission electron microscopy.

- Marchantia polymorpha serves as a model organism to study how different light wavelengths (red, far-red, blue, and green) affect key physiological and biochemical processes, providing insights into photoreceptor systems due to its simplicity.
- The study investigated the effects of these light types on photosynthesis, transpiration, and gene expression related to light and hormones, finding that far-red light resulted in chloroplast structural changes that decreased photosynthesis, while blue light enhanced gene activity for secondary metabolite production.
- Results showed that far-red light influenced the expression of genes related to phytochrome and morphology, leading to significant changes in gametophyte structure alongside variations in photosynthetic performance.
Pollen germination in vivo on wet stigmas is assisted by the receptive fluid-stigma exudate. Its exact composition is still unknown because only some components have been studied. For the first time, hormonal screening was carried out, and the fatty acid (FA) composition of lipid-rich () and sugar-rich () exudates was studied.
