Description
Huihong Shi and collaborators compare magnesium handling in the two founding sugarcane species in a 2026 study. Magnesium is central to chlorophyll and photosynthesis, yet how the two species regulate it was unknown. The transporter gene family for the mineral was listed in both species, activity was tracked across leaf development and daily cycles, and one carrier gene was tested in bacteria and in rice.
The two species responded differently to mineral supply, and their versions of the transporter gene followed distinct expression patterns. Both versions restored mineral uptake in a deficient bacterial strain, confirming shared transport ability. Boosting the wild species version in rice raised growth under low mineral levels and tolerance of excess. Promoter analysis pointed to different control factors in each species, suggesting distinct strategies for mineral balance.
