Issue 89 of Haustorium is now available, featuring the latest developments and discoveries in parasitic plant research. Highlights include the first confirmed report of sunflower broomrape (Orobanche cumana) in North America, raising concerns for sunflower production, and a fascinating feature on the striking purple toothwort.
This issue also includes updates on combating Striga, from genome editing research to the expanding impact of the Toothpick Project across Kenya, Uganda, and Tanzania. Readers can discover rare and extraordinary parasitic plants from around the world, including rediscovered species once thought extinct.
As always, Haustorium includes recent theses, publications, and updates from the International Parasitic Plants Society, along with news about the postponed 18th World Congress on Parasitic Plants. The issue also once again contains an extensive Literature section featuring more than 180 recent research articles and publications from around the world.
Special thanks go to Chris Parker, whose tremendous effort once again made this issue possible, and to Lytton Musselman for his continued support and contributions to the parasitic plant community.
