In 2022, we were pleased to see the fruits of our efforts to promote interdisciplinary projects as three Alliance led or supported collaborative, interdisciplinary projects addressing knowledge gaps in various components of phytobiomes began. With this success, we expanded the Alliance structure by adding four Working Groups tasked by the Coordinating Committee to lead, identify gaps in resources or knowledge, and coordinate specific aspects within disciplines and technologies. And, last but not least, we were thrilled to finally meet in person at the International Phytobiomes Conference held September 2022 in Denver, Colorado.
