Cíle předmětu

The objective of this course is to familiarize the students with plant research (more specific point below).
Give a brief historical overview how plant research has contributed to the development of science at large.
Familiarize the students with methods of genetics, molecular and developmental biology as well as cell biology used in plant research.
Introduce the role of AUXIN hormone in plant development.
Discuss the cellular and molecular mechanisms facilitating auxin function (signalling and transport).
Highlight the role of other plant hormones.

Výstupy z učení

Student will be able to:
- Use the laws of genetic trait segregation (Mendel laws) and interpret the results of genetic crosses;
- Apply basic molecular biology techniques to design genetic constructs used for elucidation of gene function or utilized to alter the function of a gene or protein produced by the gene;
- Apply principles of Forward and reverse Genetics strategies in the identification of gene function;
- Apply basic biochemical techniques to link the protein to the gene and understand the gene function;
- Apply basic cell biology techniques to link the protein to the gene and understand gene function;
- Utilize the knowledge of plant hormonal signaling to modify aspects of plant development;

Theory class: lectures, class discussions.

Metody hodnocení

Assessment methods:

Assessment will be based on the interaction with students during the course (Questions, Discussions). Student activity will be recorded and will have an influence in the calculation of the final mark.

Final oral exam will consist of multiple questions concerning the subject matter of the course. The answers on the questions will be scored and summarized in as final performance percentage; bonus % for activity during the course will be added.

There are 2 modes of course completion:

a) Colloquium – the evaluation will be represented as pass (Z- above 50,1 % of correct answers) or fail (N) grade/result. 1 additional credit will be awarded for finalising the course with the colloquium (3 points in total for this completion variant).

b) Exam – it will commence in the same fashion as colloquium, but the final result will be graded (from F = worst grade to A = best grade). 2 additional credit(s) will be awarded for finalising the course with an exam (4 points in total for this completion variant).

Scoring system (% of correct answers):
F-(0,0-50,0)
E-(50,1-60,0)
D-(60,1-70,0)
C-(70,1-80,0)
B-(80,1-90,0)
A-(90,1-100,0)

Informace učitele

The course will be taught (lectures) on Mondays, 2 – 4 pm, room E26, 2.22 or on-line in this time, pre-recorded lectures and then consultation on MS-Teams or directly lectures on MS-Teams (preferred).

The schedule encompasses 12 weeks: start February 21, end 16th May last lecture (2022). The exact exam time is usually arranged with students during the course, two exams dates are given and then two dates to correct the mark if not satisfactory (during corrections difficulty of questions increases).

Location of the course will be in the building E26 (former A26), 2nd floor, room 2.22.

When You have taken this course consider taking, in parallel or subsequently, the complementary course S2011.
