Objectives and Contextualisation
The general goal of this subject is to provide the required knowledge to understand the molecular bases of plant biology, as well as the techniques and basic aspects of plant biotechnology, with important social implications as well as the use of transgenic plants or Genetically Modified Organisms (GMOs).
At the end of this subject, students should be able to have their own criteria on issues of plant biotechnology with social repercussion, based on contrasting knowledge.
The topics that will be addressed in the subject can be seen in the content section.
Competences
- Act with ethical responsibility and respect for fundamental rights and duties, diversity and democratic values.
- Apply knowledge of theory to practice.
- Apply scientific method to problem solving.
- Be able to analyse and synthesise.
- Describe the genetic bases of the development and control of genic expression.
- Design and execute complete protocols of the standard techniques that form part of molecular genetics instruments: purification, amplification and sequencing of genomic DNA from biological sources, genetic engineering in microorganisms, plants and animals.
- Develop self-directed learning.
- Make changes to methods and processes in the area of knowledge in order to provide innovative responses to society's needs and demands.
- Reason critically.
- Take account of social, economic and environmental impacts when operating within one's own area of knowledge.
- Take sex- or gender-based inequalities into consideration when operating within one's own area of knowledge.
- Use and manage bibliographic information or computer or Internet resources in the field of study, in one's own languages and in English.

Content
The subject will be organized in two sections: a first section in which theoretical knowledge will be imparted and a second one in which students will learn by the resolution of different scientific problems.
In relation to the first section of the subject, students will learn the following concepts and knowledge:
-Structure of a plant gene: from the transcription to the functional protein.
-Plant transformation: via Agrobacterium tumefaciens, via bio-ballistics, via chemical mutations.
-Generation of transgenic plants by over-expression of a gene of interest (with the promoter 35S), or repression with the technique of RNAi.
-Gene-editing using the CRISPR-Cas technique.
-Mutants: what they are, why they are used for, how are they generated, the importance of mutant collections.
-Arabidopsis thaliana as a model organism and its comparison with other plants.
-Use of bioinformatics platforms for molecular biology studies.
-omics techniques for the study of the regulation of gene expression.
In relation to the second section of the subject, students will have to solve proposed problems in the field of plant molecular biology.
The theoretical content will be evaluated with an exam that will be the main body of the final mark.
Methodology
Methodology
The formative activities will be: theory, seminars and laboratory.
Theory
Teachers will explain the contents of the subjects using material available on the Internet. These lectures will be the first part of the subject. The knowledge of some parts of the subjects will have to be also developed by the students, by means of autonomous learning. To facilitate this task, we will provide information on textbooks, web pages, scientific articles related to the topic ...
Seminars
The seminars will be given by the students, individually or in groups, depending on the number of students and the availability of time.
The students will have to present in 10 minutes a current problem of plant molecular biology and emphasize the objectives for its resolution.
The topics that will cover the seminars will be decided at the beginning of the course. The aim of these sessions is to deepen the knowledge given in the lectures, as well as to have discussion on topics of special interest for the students.
The seminars will be evaluated, with an impact on the final mark.
Laboratory
The practical classes of laboratory will consist of 3 sessions of 4 hours each one. The protocols used will be provided at the beginning of the academic year. During these sessions, experimental skills in some of the basic issues of plant biotechnology will be acquired.
The practices will be evaluated, having an impact on the final mark.
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
Laboratory practices, seminars and the acquisition of knowledge corresponding to the subject explained and worked in theoretical classes will be evaluated separately. Attendance to the laboratory sessions is mandatory. Failure to meet this requirement will imply that the student loses the right to be evaluated in the rest of the evaluation parts. Students missing more than 20% of programmed sessions will be graded as "No Avaluable".
Once the practices have been approved, it will not be necessary to do them again, even if the student may enroll in this subject again. The following aspects will be evaluated: 1) attitude and participation; 2) experimental results obtained; 3) final report. The report, with a length of between 5 and 10 pages, will consist of a presentation of the results obtained and in the elaboration and critical discussion of these results. The maximum mark for laboratory practices is 2 points.
The seminar corresponds to the elaboration and a brief exposition of a research project in the presence of the whole class. The maximum possible mark for the seminars is 1 point.
The acquisition of knowledge corresponding to the subject explained in the theoretical classes will be evaluated by means of:
An exam in the middle of the teaching period, which will be qualified with a maximum mark of 4 points.
An exam at the end of the teaching period, which will be qualified with a maximum mark of 3 points.
The final mark of the subject will be obtained by the sum of all the marks obtained in the different parts (laboratory, seminars and theory). Approving the subject will involve obtaining a minimum of 5.0 total points. In addition, to approve the subject, the sum of the marks of the theory exams may not be under 3 points, with a maximum of 7.0 points. Otherwise, the subject will be suspended, although the sum of the different notes gives a score of 5.0 or more.
Students who have not passed the subject will have the option to be re-evaluated of the theoretical part. To be eligible for the retake process, the student should have been previously evaluated in a set of activities equaling at least two thirds of the final score of the course. Thus, the student will be graded as "No Avaluable" if the weighting of all conducted evaluation activities is less than 67% of the final score"
The students who wish to improve their mark will have also access to the retake process. In this case it is understood that they renounce the previously obtained theory mark.
