Biological assessment of the Rožmitál quarry
Samková, Věra ; Mikát, Miroslav ; Mocek, Bohuslav ; Branda, Jaroslav
Bylo v celém areálu lomu bylo doloženo 287 druhů rostlin a 631 živočichů, z toho jsou chráněny podle Vyhlášky MŽP 395/92 Sb. tyto druhy: krajník hnědý (Calosoma inquisitor), střevlík Scheidlerův (Carabus scheidleri) a otakárek fenyklový (Papilio machaon), ropucha obecná (Bufo bufo), ještěrka obecná (Lacerta agilis).. Jsou posouzeny vlivy rozšíření těžby na rostliny a živočichy a navržena kompenzační opatření v rekultivované části lomu (Homole).

Rostliny pro střešní zahrady
Jílková, Kristýna
This Diploma thesis focuses on green roofs plants. The literary research covers attributes that are critical for choosing the right plants for green roofs and is defining qualities that are important for designing, founding and nurturing them. The theses address selection of plants that are suitable for extensive gardens. Plants that were recommended by authors were compared with those available on the Czech market. The experimental part of this theses evaluates several green roofs according to the methodology. The emphasis is put on plant vitality assessment. Field research results were compared with the literary research.

Effectors of RAB GTPases and their role in plant secretion
Růžičková, Martina ; Hála, Michal (advisor) ; Motyka, Václav (referee) ; Klíma, Petr (referee)
Rab GTPases are small signaling molecules that play an important role in vesicle trafficking in eukaryotic cells. Correct signaling through small GTPases allows orchestration of vesicle transport among cellular organelles and also to the cell wall providing cell wall material for cell growth and elongation. Engagement of Rab GTPases in the regulation of endomembrane trafficking is one of the evolutionary conserved aspects of secretion regulation. The network of Rab GTPases interaction includes also various downstream effectors. One of them is the exocyst complex involved in vesicle docking at the plasma membrane. It is a complex composed of eight different subunits (Sec3, Sec5, Sec6, Sec8, Sec10, Sec15, Exo70 and Exo84). Exocyst was discovered as Sec4p Rab GTPase effector in yeast and also data from animal models describe the Sec15 exocyst subunit as the Rab-interacting partner, but data from plants are missing. On the other hand, numerous studies identified exocyst role in tip growth of pollen tube and root hairs, seed coat formation, cell plate and cell wall formation, hypocotyl elongation, and importantly also PIN auxin efflux carriers recycling and polar auxin transport. There are two paralogues of SEC15 in the Arabidopsis genome, SEC15a and SEC15b, the previous one already shown to be...

The effect of N fertilization on plant growth during primary succession
Müllerová, Věra ; Frouz, Jan (advisor) ; Mudrák, Ondřej (referee)
Nitrogen as the fourth most educated element of living organisms and the limiting factor of the aquatic and terrestrial ecosystem is still a major problem for scientists around the world. Today, developed countries are able to store their inputs in the form of depositions in the same values, but there is a question of long-term effects of chronic nitrogen add-ons. The aim of the thesis is to compare the effect of long-term and one-time fertilization on various plant species, especially on grass and nitrogen fixation plants in relation to the age of the soil on which they grow. This connection will be investigated by the ANOVA method in a practical experiment on selected plants growing on different old soils that have been or have not been fertilized for long periods with nitrogen. As model organisms, I chose a nitrogen fixing device, Lotus corniculatus, and Festuca rubra an unstable plant, which is also a representative of the grass. One-off fertilization had a positive effect on the growth of above-ground biomass on all plants. We have a different impact according a type of plant on long-term fertilization. In this case, I recommend more detailed testing of a wider sample of plants.
