Curricular information is subject to change.

The cell is the basic building block of eukaryotic organisms, and understanding how cells develop and their physiological responses to the environment are key to our understanding of plant growth and development. This module expands on your understanding of basic cell biology by using the stomatal guard cell as the system to understand plant cell biology. This series of lectures will explore the genetic and molecular regulation of stomatal development and how stomatal guard cells respond to internal and external signals through changes in ion transport to effect changes in stomatal guard cell turgor. Practical components of this module include demonstrations of (i) advanced microscopy techniques (including laser scanning confocal microscopy), (ii) biolistic transformation, and (iii) techniques to assay for stomatal function and stomatal development.\

### What will I learn?

###### Learning Outcomes:

On completion of this module, you will have a clear understanding of stomatal development and the basic processes underlying turgor changes in plant cells. You will also have a fundamental understanding of ion-based signalling systems in plant cells. You will also have an appreciation of fluorescence and laser scanning confocal microscopy, data interpretation, along with writing and communication skills essential for a practising scientist.

###### Indicative Module Content:

Key topics covered will include:\
(1) Ion transport\
(2) roles and functions of transport proteins (pumps, channels)\
(3) functions of transport proteins and ion transport in plant cell physiology\
(4) second messengers in cellular signalling \
(5) developmental genetics of stomatal development
