The 14th Nordic Photosynthesis Congress

From Basics to Redesigning Photosynthesis
#npc14 #npc14turku #nordicphotosynthesiscongress

Program

The program of NPC14 covers structures and evolution of photosynthetic complexes, regulation, and acclimation of photosynthesis, as well as bioengineering and synthetic biology for improvement of photosynthetic yield and production of valuable biocompounds. It will not be divided into distinct sessions, but all participants are asked to take into consideration the theme of the conference in the presentations.

The program will be comprised of invited lectures, oral presentations (15 + 5 min), and short flash presentations given by young researchers (5 min). Posters will be presented in electronic form in separate poster sessions.

Oral presentations

Oral presentations (15 + 5 min) and short flash presentations (5min) will be selected based on the abstracts (deadline for submission 27 March). Please indicate in the registration form your willingness to give a presentation. Notification for the accepted oral presentations will be confirmed at the beginning of April. Others have the opportunity to present an electronic poster (see below).

Standard audiovisual equipment, laser pointer, wireless slide advancer and microphones, will be available for use during oral presentations. The lectures will be installed on a communal computer from a pocket memory stick, but also your own laptops may be used. Speakers are kindly asked to report to the session chair no later than 20 minutes prior to the start of their session. Technical staff will be available for assistance during this time.

Electronic posters

Electronic posters will be presented e.g. as a PowerPoint show. Bring your own laptop and prepare a short (ca. 3-5 min) presentation in the form that it will run automatically during the given poster session. The presenter is kindly asked to be at the poster during the session.
