Hafidh S, Potěšil D, Fíla J, Čapková V, Zdráhal Z, Honys D. Quantitative proteomics of the tobacco pollen tube secretome identifies novel pollen tube guidance proteins important for fertilization. Genome Biology. 2016; 17:81. doi:10.1186/s13059-016-0928-x. IF 11.91
The identification of novel genome-wide pollen tube-secreted proteins with potential functions in pollen tube guidance towards ovules for sexual reproduction. Confocal microscopy has been used to show the association of pollen tube-secreted proteins with marker proteins, shown to be secreted via exosomes in other species.
Kulich I, Vojtíková Z, Sabol P, et al. Exocyst Subunit EXO70H4 Has a Specific Role in Callose Synthase Secretion and Silica Accumulation. Plant Physiology. 2018;176(3):2040-2051. doi:10.1104/pp.17.01693. IF 5.949
The first evidence on the existence of exocyst subunit EXO70H4 plasma membrane microdomains importance for the deposition of callose in plant trichomes. Spinning disk microscopy was used for subcellular localizations assays.
Rawat, A., Brejšková, L., Hála, M., Cvrčková, F., & Žárský, V. (2017). The physcomitrella patens exocyst subunit EXO70.3d has distinct roles in growth and development, and is essential for completion of the moss life cycle. New Phytologist, 216(2), 438-454, IF 7.43
The first functional analysis of the moss exocyst subunit from Physcomitrella patens PpEXO70.3d. Confocal microscopy has been used for the subcellular localization assays.
Platre MP, Noack LC, Doumane M, Bayle V, Simon MLA, Maneta-Peyret L, Fouillen L, Stanislas T, Armengot L, Pejchar P, et al. 2018. A Combinatorial Lipid Code Shapes the Electrostatic Landscape of Plant Endomembranes. Developmental Cell 45: 465–480.e11. IF 9.62
Definition of lipids that control membrane electrostatics in plants Phosphatidylinositol-4-phosphate (PI4P), phosphatidic acidic (PA), and phosphatidyl- serine (PS) were shown to be separately required to generate the electrostatic signature of the plant plasma membrnae. Confocal microscopy was used for time lapse imaging of pollen tube growth in this work.
