On the origin of plastids: new insights from elusive marine microbes

The ori­gin of the pho­to­syn­thetic or­gan­elles–the plast­ids–in eu­k­a­ryotes, some 1.5-2 bil­lion years ago, was one of the most trans­form­at­ive events in the his­tory of life. It res­ul­ted in an ex­plo­sion of di­versity of trees and all eu­k­a­ryotic al­gae, al­low­ing life as we know it to evolve. Des­pite this crit­ical im­port­ance, however, we still know little of the evol­u­tion of the early pho­to­syn­thetic eu­k­a­ryotes. In this present­a­tion, I will first provide a brief re­view on the ori­gin of plastid by en­dosym­bi­osis, and where in the eu­k­a­ryotic tree of life we find plast­ids. I will then show how the dis­cov­ery and re­cent single-cell ge­n­om­ics of an elu­sive mar­ine mi­cro­bial eu­k­a­ryotic group–the Pi­co­zoa–com­plexi­fies the cur­rent paradigm of plastid ori­gin. I will con­clude by present­ing a new model of plastid ori­gin that in­cludes a di­versity of deep-branch­ing un­known taxa sim­ilar to Pi­co­zoa, which I ar­gue need to be dis­covered and ac­coun­ted for.
