This episode is hosted by Mr. Kranthi kiran Akula, a graduate student from India. Today we have with us Dr.Enrique Lopez-Juez and Dr.Naresh Loudya from the Royal Holloway University of London. Dr.Lopez and Dr.Naresh would be sharing details of their new and exciting findings recently published in ‘Philosophical Transactions of the Royal Society B’ and the paper is titled “Retrograde signalling in a virescent mutant triggers an anterograde delay of Chloroplast biogenesis that requires GUN1 and is essential for survival”.
