Elevated CO₂ Priming as a Sustainable Approach to Increasing Rice Tiller Number and Yield Potential.

ABSTRACT: Tillering and yield are linked in rice, with significant efforts being invested to understand the genetic basis of this phenomenon. However, in addition to genetic factors, tillering is also influenced by the environment. Exploiting experiments in which seedlings were first grown in elevated CO₂ (eCO₂) before transfer and further growth under ambient CO₂ (aCO₂) levels, we found that even moderate exposure times to eCO₂ were sufficient to induce tillering in seedlings, which was maintained in plants grown to maturity plants in controlled environment chambers. We then explored whether brief exposure to eCO₂ (eCO₂ priming) could be implemented to regulate tiller number and yield in the field. We designed a cost-effec
