Objectives

The main objective of this Course is for the students to complement their knowledge about how plants work and how they respond to environmental stimuli. This optional course complements the knowledge gained at the Plant Physiology course, focusing on more peculiar aspects of plant physiology that are not addressed in the basic course. Since plants are complex organisms, this course explores aspects that make them unique, focusing especially on the biochemical and molecular processes involved in their growth, development and interactions with the environment.

Learning outcomes and competences

The frequency of the course should allow students to have the competence and capacity to:

• Show knowledge on plant physiology


• Understand some plant movements in response to external stimuli


• Understand how different types of photosynthesis represent advantages in different environments


• Explain how plants use products resulting from photosynthesis


• Know particular aspects about the respiration in plant physiology


• Understand how plants interact with biotic agents such as parasites, herbivores and other plants


• Understand the importance of the secondary metabolism to the plant and to humans


• To know the most used techniques in the transformation of superior plants, as well as the vegetal models most used in the area of Plant Physiology


• Understand how assimilations of Nitrogen and Sulfur are processed and how these relate to the Carbon metabolism


• Recognize that oxidative stress is a consequence of plant exposure to conditions adverse to their growth and development and that the antioxidant system is an important defense mechanism.


• To know some signal transduction process

Program

Theoretical program:
Plant movements: Tropisms and nastic movements. Physiological and ecological considerations about photosynthesis. Allocation and distribution of photoassimilates within the plant. Particular aspects of respiration in plant physiology. Assimilation of Nitrogen and Sulfur and coordination of the assimilation of these nutrients with the Carbon metabolism. Reference to the most used model plants in plant physiology and plant transformation. Plant responses to attack by biotic agents: parasites, herbivores and competing plants and parasitic plants. Oxidative stress and antioxidant defenses. Signal transduction.

Practical program
Quantification of the photossynthetic efficiecy in different light conditions. Quantification of starch, sucrose, glucose and fructose in starch-accumulating plants and sucrose-accumulating plants at different times of the day. Evaluation of the activity of Glutamine Synthase by spectrophotometry and native gel. Visualization of green fluorescent protein (GFP) expression after foliar infiltration with Agrobacterium. Regulation of alpha-amylase by gibberellic acid during the germination of barley seeds. Activity of nitrate reductase in different conditions.

Teaching methods and learning activities

Theoretical classes of expositive-interrogative nature supported in projections.
Practical classes that provide the acquisition of specific skills, namely those that result from the execution of practical laboratory work.

The scheduling of practical classes, as well as the set of procedures for each laboratory work, are available to students on the course website.

Eligibility for exams

A student gains attendance if:

1. Having been regularly enrolled, do not exceed the limit of absences corresponding to 25% of the practical classes provided (https://sigarra.up.pt/up/LEGISLACAO_GERAL.ver_legislacao?p_nr=4025).

Practical classes of compulsory attendance.

Calculation formula of final grade

Students should choose a modality of knowledge assessment:
i) Final exam
OR
(ii) Frequencies

I. Final written exam (Theoretical component and Theoretical-Practical component)

- Theoretical examination (T), 20 val.

- Theoretical-practical exam (TP), 16 val.

- Presentation and discussion of a practical work, to be defined, carried out during practical classes (AP), 4 val.
Final Note - [2T + (TP + AP)] / 3


II.Frequencies

- 2 Theoretical evaluations (FT1 and FT2), each 20 val.
- Theoretical-practical exam (TP), 16 val.

- Presentation and discussion of a practical work during the practical classes (AP), 4 val.
 

- Final grade - [2 (mean FT1 + FT2) (TP + AP)] / 3

Minimum Notes: component T, 8 values
                         component TP, 6.5 values

The first frequency will be held in the middle of the semester. The second frequency will be held on the day of the normal period examination.

Approval to this subject is obtained with a final clasification equal or superior to 9.5 values.

Examinations or Special Assignments

Presentation and discussion of assigned practical work (4 values).

Special assessment (TE, DA, ...)

Distributed evaluation
OR
Final written exam

Classification improvement

To improve the final grade, the student needs to request a new exam, in accordance with the current legislation on the subject.

Evaluation Components:

Theoretical (T) (20 values) + Theoretical-practical (TP) (16 values);

Grade obtained with the presentation of practical work (P) (4 points).

FINAL CLASSIFICATION = [T + (TP + P)] / 3

There are no precedents.
