Green Carbon Food Security Transcriptomes Regulomes

Green Carbon is the organic ‘living’ carbon stored in the biosphere, captured through photosynthesis, a process critically dependent on the activity of RubisCO – a key enzyme in the global carbon cycle. RubisCO is arguably the most abundant protein on our planet, feeding all life on Earth, but much of this abundance can be ascribed to its inefficiency. Over the last 600Mya, nature has optimized ways to overcome this flaw by evolving methods of photosynthetic carbon acquisition, collectively called the Carbon Concentrating Mechanisms (CCM). In this talk, I will present our work on marine algal CCM to improve RubisCO efficiency for higher biomass production and, in turn, food security. We investigate biophysical CCM in the unicellular green alga Chlamydomonas reinhardtii (or Chlamy), by constructing and superimposing Spatio-temporal molecular networks of key physiological processes in the diurnal cycle and devising ways to reduce data dimensionality via supervised and unsupervised clustering strategies.
