First Plant Cell Atlas Symposium

Virtual Symposium
December 9 & 10, 2021

Objectives

The goal of the Plant Cell Atlas (PCA) is to bring together a community who will comprehensively describe plant cell types by integrating high-resolution subcellular and cellular location information of nucleic acids, proteins, and metabolites.

Symposium Goals:
1) Share the most exciting scientific and technological breakthroughs in plant single cell science.
2) Create a forum for people interested in plant single cell approaches to meet and network.
3) Discuss community building and how PCA relevant data could be analyzed, annotated, and accessed.

Each day will consist of three oral sessions and two poster sessions. Each oral session will feature one invited speaker and 2 speakers selected from abstract submissions. Each oral session will also include time to discuss PCA community building and data handling. Further details of the agenda will be posted here in the upcoming months.

Recordings of the five of the talks can be found on the PCA YouTube channel.
