Advancing Plant Science Through Diverse Perspectives
Behind the innovative manuscripts published in Plant Physiology during May and June 2024 are researchers, professors, professionals and students dedicated to expanding the frontiers of plant science. These First Authors come from various backgrounds and bring unique experiences that inform their scientific work and passion for plants.
Exploring the Interplay of Auxin, Nitrate, and Tissue Adhesion
Phanu Theodore Serivichyaswat, a Researcher at the Swedish Museum of Natural History, is the First Author of the article “Auxin signaling in the cambium promotes tissue adhesion and vascular formation during Arabidopsis graft healing.” Serivichyaswat’s research interests focus on plant genomics and evolution, inspired in part by Taylor Swift’s use of plant-themed imagery in her music.
“Taylor Swift has inspired me to love plants and plant science. She often uses plant-themed imagery and metaphors in her music. In songs like ‘Out of the Woods’, ‘Clean’, and ‘All Too Well’, she uses references to forests, trees, and leaves to convey emotions and themes of growth, renewal, and resilience. I became aware of the important role of plants in our culture and scientific community through Swift’s music.”
Serivichyaswat’s work examines how auxin signaling in the cambium, the tissue responsible for secondary growth, facilitates the adhesion and formation of vascular tissues during graft healing in Arabidopsis. Understanding the molecular mechanisms underlying this process can provide insights into improving grafting techniques, which are crucial for fruit tree cultivation and the vegetative propagation of other economically important plants.
