A Central Role for Genetics in Plant Biology (Annu. Rev. Plant Biol.)
Plant Science Research Weekly
Plant biology as a field of study encompasses a rich plethora of subjects, some of which themselves are their own fields. Maarten Koornneef, in this memoir-style article, describes how genetics in particular shaped his career that saw the rise of Arabidopsis as the lovable poster child of plant biology…
