Prerequisites

Basic knowledge of Plant Physiology, Genetics and Molecular Biology.

Objectives

To transmit the knowledge necessary to understand the main processes of plant adaptation to different environmental conditions, including responses to stress. To know the molecular mechanisms and genetic networks regulating these processes.

Contents

Plants are frequently exposed to environmental stress conditions (biotic and abiotic) that adversely affect growth and development, or productivity. These adverse conditions trigger a wide range of plant responses, from alterations in gene expression and cellular metabolism to changes in growth rate and crop yield, which are conditioned by the duration, severity and rate at which a stress is imposed, as well as by the combined action of several of them. Moreover, resistance and sensitivity to stress vary according to species, genotype, developmental stage, and organ or tissue type. This module will describe how the different environmental cues affect plants at different levels, as well as the molecular mechanisms evolved by these sessile organisms to defend against stress conditions.


Abiotic stress:


• Oxidative stress
• Salinity and drought
• Ionic stress
• Floods
• Temperature


Biotic Interactions:


• Cell death
• Pathogenic microorganisms
• Beneficial microorganisms
• Microbiome


Biotic and abiotic stress interactions.

Learning activities and methodology

Title Hours ECTS Learning outcomes
Tutorials 4 0.16
Seminars preparation 12 0.48
Lectures 30 1.2
Study 90 3.6
Seminars 8 0.32

Theoretical lectures:

Within this module, master or expository lectures represent the main activity to be performed in the classroom and allow basic concepts to be transmitted to students in a relatively short time. They will be complemented with Powerpoint presentations, thus the methodology is mainly based on verbal communication, accompanied by visual schemes. Teacher's direct questions to students during the class are indicative of the student's degree of follow-up. Bibliographical references and other sources of information are given to foster self-study.


Seminars:

They are work sessions, based on work proposed by the teachers that the students will work autonomously. The main purpose of the seminars in this subject is to promote the knowledge of the general and transversal competences of the students. The teaching methodology is based on the exposition and discussion of a scientific article in the classroom. Students have to search for and select an adequate article according to the quality criteria explained by the teacher.



The use of Artificial Intelligence (AI) technologies is permitted in this course exclusively for support tasks, such as literature or information searches, text editing, or translation. Students must clearly identify any parts of their work generated using AI, specify the tools used, and include a critical reflection on how these tools influenced both the process and the final outcome of the assignment.

Failure to disclose the use of AI in an assessed activity will be considered a breach of academic integrity and may result in a partial or total reduction of the activity grade, or more severe disciplinary measures in cases of serious misconduct.


Tutoring:

In tutorials in groups or individually, the professor tries to help the students to solve their doubts about the concepts of the subject and guide them in their studies.

Annotation: within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Seminars 40% 4 0.16 CA13, CA14, SA20, SA21, SA22, SA23
Written exam 60% 2 0.08 KA11, KA12, SA22

Assessment is based on the following components:

  • Multiple-choice written examination, designed to assess the content covered in the lectures, accounting for 60% of the final grade.
  • Seminars: Attendance at seminars is mandatory and accounts for 40% of the final grade. Assessment activities carried out during the seminars cannot be retaken. Absences that are duly justified in accordance with UAB regulations will not result in any penalty. In the case of an unjustified absence, the seminar grade will be reduced according to the following criteria:

1 absence: 20% reduction of the seminar grade.

2 absences: 40% reduction of the seminar grade.

3 absences: 80% reduction of the seminar grade.

More than 3 unjustified absences: the course will be considered failed.


To pass the course, students must obtain a minimum grade of 5.0 in the written examination and an overall final grade of 5.0 or higher.

This course does not offer the single assessment option.

Students who do not sit the written examination will receive a grade of "Not Assessable", as they will not have provided sufficient evidence for assessment.


Any irregularity committed during an assessment activity (including academic fraud, plagiarism, or the improper use of Artificial Intelligence (AI), unless such use is explicitly authorised in the course guide) that may lead to a significant alteration of the assessment outcome will result in a grade of 0 for that assessment activity. If the course guide establishes that obtaining a minimum grade in that assessment activity is an essential requirement for passing the course, or if multiple irregularities are committed in the assessment activities of the same course, the final grade for the course will be 0. In addition, students who commit any of these irregularities may be subject to disciplinary proceedings in accordance with the University's regulations.
