Dawn of a new era for parasitic plant biology.

Parasitic Plants
Dodder, that orange thread-like tangle strangling plants in your garden beds, and the ghost-like broomrape erupting under your tomatoes belong to a poorly understood group of plants that genomics is only now cracking open — meaning targeted, chemical-free controls may finally be on the horizon.
Some plants skip photosynthesis entirely and instead tap into a neighboring plant like a parasite, draining it of water, sugars, and nutrients through a specialized attachment called a haustorium. For a long time, scientists struggled to study these plants because their genomes are strange and complex. New DNA-reading technologies are changing that, opening the door to real breakthroughs in understanding — and fighting — these fascinating biological thieves.
Key Findings
Advances in long-read genome sequencing have made it feasible to assemble the complex, often bloated genomes of parasitic plants for the first time at scale
The field is converging on shared molecular mechanisms by which parasites sense and invade host roots, offering potential universal intervention targets
New model systems and genetic tools (including CRISPR) are being established in parasitic plant lineages, enabling functional experiments that were previously impossible
chevron_right Technical Summary
A landmark perspective piece signals that parasitic plant science is entering a transformative phase, driven by new genomic tools and sequencing breakthroughs that are finally making it possible to study — and potentially control — plants that steal water and nutrients directly from host roots and stems.

Cuscuta, commonly known as dodder or amarbel, is a genus of over 201 species of yellow, orange, or red parasitic plants. The genus possess minimal chlorophyll and utilize haustoria to extract nutrient and water from host's vascular system. Formerly treated as the only genus in the family Cuscutac...
