Debashish Bhattacharya and Professor Juliet Brodie from the Natural History Museum in London co-organize a Theo Murphy international scientific meeting from June 8-9, 2016 funded by the Royal Society entitled, "Into the genome: advances in the world of algal genomics." The event will take place at the Kavli Royal Society Centre, Chicheley Hall, Buckinghamshire, United Kingdom.

The research used information from 20 genomic datasets to understand how stony corals live and have survived for over 240 million years.

Research associate Huan Qiu led a study focusing on the question why the terrestrial environment become green and not red, published in the Journal of Phycology.

image of Slim Karkar Post-doc Slim Karkar publishes a paper in PNAS on the evolution of metabolic connectivity in algae
Slim's collaborative paper shows that plastid transporters are mostly of host nuclear
origin with some key components provided by foreign bacteria through horizontal gene
transfer (HGTs). This work supports the hypothesis that creation of new organelles is directed
by the host cell with the endosymbiont making a smaller contribution to host-plastid connectivity.

Arik is now situated in the Department of Vegetable Research, Institute of Plant Sciences, Volcani Center, in Bet Dagan. This follows on a successful stay at Rutgers where he worked in the Yana Bromberg and Bhattacharya labs on a collaborative project led by Paul Falkowski on the origin and evolution of redox enzymes in the earliest microbial life forms.

NSF Fuels IGERT program-funded graduate student Fatima Foflonker publishes a paper about the genome of the halotolerant green alga Picochlorum that provides insights into how horizontal gene transfer can lead to adaptation to stressful environments. This alga also offers promise for biofuel and other biotechnological applications. The work was done in collaboration with the group of Brian Palenik at the Scripps Institution of Oceanography, University of California, San Diego.

Bhattacharya, Price, Yoon et al. publish a paper in Scientific Reports
This paper shows that cyanobacteria that gave rise to a novel plastid in Paulinella chromatophora are eaten by its phagotrophic sister Paulinella ovalis and that this food is the source of horizontally transferred genes in P. ovalis. The results, for the first time, connect food, foreign gene transfer, and primary endposymbiosis in a single lineage.
