Mistake / lesson learnedAlways think

‘What is the control’

Mistakes made??

Control of flowering History

Lighting to control development in commercial species

PhotoperiodismLight detecting systemTiming system

Phytochrome

Multi-gene family; different functions

FeaturesTemperature compensatedContinue under constant conditionsFrequency is about 24h; daily L/D entrain to exactly 24hPhase shifted by light

Are there two actions of light (external coincidence), or just one (internal coincidence)?

control

Phase delay

Phase advance

Short light interruptions of long dark period

Seedlings given 24h light, then either:a. 48 h dark, orb. Different durations of R at the 6th h, orc. Different durations of R at the 8th hBatches (12) from each treatment then given 10min R interruptions over rest of the dark period

Lessons learned – science research

Control the variables Devise a model Physiology is important to establish the parameters for genetic

control

Scientific curiosity is universal

Science is competitive: King and Heide discussion

Reflective writingCareers moduleKath Houston

Link to module learning outcomes3. Carry out critical reflection on your own professional progress and plan for future professional development over the long, medium and short term. 4. Actively contribute to a community of practice 5. Demonstrate engagement with professional ethics and values espoused by the University and Professional Bodies, regarding inter-alia inclusivity, quality assurance and enhancement

Lessons learned

Good at collaboration

Crucial importance of functioning communities of practice

Responsibility as supervisor

Not very good at writing up for publication!
