- Competencies: Knowledge: Have detailed information on the physical properties of light and on its interactions to livings Knows the role of light as source of energy in photoautotrophic organisms Familiar with the process of converting of the energy of light into chemical energy Has high level of knowledge of the structure and function of the photosynthetic apparatus in land plants, and in models of Chlorophyta, Bacillariophyceae, Phaeophyceae and Cyanobacteria. Know the operation of non-photochemical quenching Knows the light regulated processes in angiosperms Has a high level of knowledge on the operation and signalling pathways of the photoreceptor systems of Arabidopsis thaliana Knows the details of the photobiological aspects of germination and flowering Understand the inhibitory aspects of light on the physiological processes of plants Has detailed information on the light induced damages in the photosynthetic apparatus and on the defence mechanisms. Ability: Able to characterize the photobiological aspects of the plant life in a holistic view Able to apply the gained knowledge to explain common plan biological phenomena Has the ability of argumentation on a scientific basis Able to express herself/himself on a scientifically correct way in the field of plant photobiology, both orally and in written Attitude: Engaged to integrate the gained knowledge on plant photobiology to the holistic understanding of biological sciences Open for the information based on scientific facts and for the integrative viewpoints Engaged to the ongoing expanding of her/his knowledge and open to acquire new competence. Strives to form a responsible opinion on the relation of light and the living organisms Engaged to transmit the knowledge in a scientifically correct form that is understandable for non-experts Autonomy and Responsibility: Able to form, present and independently summarize the holistic overview on photosynthesis and light regulated processes of plants. Able to analyse the corresponding scientific literature and give a scientific summary. Understand the responsibility in transmitting scientific information on a correct way. Form responsible opinion in topics on plant photobiology both for experts and non-experts.
- Course content
- The aim of the course is to introduce and discuss the advanced topics how visible light impact the life of plants as source of energy, source of information and also as a stressor. Az előadás fontosabb témái: Light as substrate, signal and stressor. Interaction of light in the plant tissues. The history of photosynthesis research. Photosynthetic pigments and their excitation. Excitation energy transfer in the photosynthetic machinery. Photosynthetic structures of chloroplasts and cyanobacteria. Structure and function of Photosystem II., I. and the Cytochrome b6/f complex. Non-photochemical quenching mechanisms. Photophosphorylation. Operation and light regulation of the Calvin cycle. Photoreceptors of the angiosperms: light perception and signal transduction of the phytochrome, cryptochrome, UVR8 systems. Metabolic and developmental processes that are regulated by these systems. LOV domain receptors and the circadian rhythm. Light regulation of chlorophyll biosynthesis and POR. Redox signalling in chloroplasts operated by Rpp and PABP-PDI systems. Retrograde signalling towards the nucleus. Integrating the chloroplast borne signals into the eukaryotic system. Light induced damages and oxidative stress. Defence mechanisms against light induced oxidative damages in the chloroplasts. Chemical, physical and movement-based defence mechanisms against excess light.
- Assessment method
- k5 = exam mark (5) (1 failed, 5 excellent) Evaluation is based on the survey of the individual performance of the students. During the semester, over participating on the presentation of the lecturer students have to give short presentations, typically in 5 minutes based on corresponding scientific literature provided by the lecturer and answer all questions based on the acquired knowledge. Lectures typically start with the presentation of a student, typically one per lecture. Student presentations are part of the course material. The course ends with an oral exam in the examination period at the end of the semester.
