Meet Balanophora, The Parasitic Plant That Barely Qualifies As A Plant – Asian Scientist Magazine

AsianScientist (Feb. 04, 2026) – At first look, you may mistake the elusive Balanophora for mushrooms. In reality, they’re parasitic vegetation that reside underground, rising solely to flower.

With out the flexibility to photosynthesise, nor a root system of their very own, they feed off the roots of host timber. Some species solely produce seeds asexually, a uncommon incidence within the plant kingdom.

“Balanophora has misplaced a lot of what defines it as a plant, however retained sufficient to perform as a parasite. It’s an interesting instance of how one thing so unusual can evolve from an ancestor that appeared like a standard plant with leaves and a standard root system,” stated Dr Petra Svetlikova, Science and Know-how Affiliate on the Okinawa Institute of Science and Know-how(OIST).

Scientists from OIST, Kobe College and the College of Taipei collaborated to check vegetation from the Balanophora genus, a difficult endeavour because the choosy vegetation parasitise only some tree species.

“These vegetation are uncommon, patchy and sometimes restricted to steep, humid forests. However years of expertise with learning Balanophora each within the lab and in discipline research, in addition to long-standing relationships with native naturalists made this mission potential,” stated Suetsugu Kenji, botanist at Kobe College.

Sampling seven species of Balanophora from 12 populations throughout Taiwan and Japan, they carried out genetic evaluation to map out the relationships between every species and learn how they tailored to their parasitic life-style.

The researchers had been notably keen on plastids – plant cell organelles which have their very own genetic materials, corresponding to chloroplasts. As parasitic vegetation turn out to be extra reliant on their hosts and abandon photosynthesis, their plastids are inclined to lose genes and even disappear solely.

Balanophora isn’t any totally different – its plastid genome is 10 occasions smaller than that of typical photosynthetic vegetation. “It’s thrilling to see how far a plant can cut back its plastid genome, which at first look appears as if the plastid is on the verge of disappearing,” stated Suetsugu. “However trying extra carefully we discovered that many proteins are nonetheless transported to the plastid, exhibiting that although the plant has deserted photosynthesis, the plastid remains to be a significant a part of the plant’s metabolism.”

The scientists additionally tracked the evolution of Balanophora’s atypical reproductive technique. Some Balanophora species are able to facultative agamospermy – producing seeds with out fertilisation, and a few are obligately agamospermous, solely reproducing on this method.

Obligate agamospermy is exceedingly uncommon in vegetation, with disadvantages corresponding to a scarcity of genetic variety, accumulation of dangerous mutations, and a better extinction danger.

“Fascinatingly, we discovered that the obligately agamospermous Balanophora species had been all island species,” stated Dr. Svetlikova. The power to breed asexually permits a single feminine plant to propagate throughout a brand new landmass by cloning itself, a bonus with regards to colonising islands.

The findings from this research are a helpful stepping stone to know non-photosynthetic vegetation and what function plastids play in sustaining them.

“Most recognized habitats of Balanophora are protected in Okinawa, however the populations face extinction by logging and unauthorised assortment,” stated Dr Svetlikova. “We hope to be taught as a lot as we are able to about this unbelievable, historical plant earlier than it’s too late. It serves as a reminder of how evolution continues to shock us.”
