Other claims from this paper (7)
- Association Both Arabidopsis phloem mutants had compromised carbon partitioning, more strongly in ops opl2.
- Association Both phloem mutants had compromised transport velocity, more strongly in ops opl2.
- Intervention effect Exogenous sucrose partially rescued ops opl2 root growth.
- Mechanism Reciprocal grafting showed that root growth defects in ops and ops opl2 were root autonomous.
- Intervention effect Sucrose supplementation rescued short roots of source-limited starch mutants.
- Association Impaired root phloem restricted growth of wild-type scions.
- Recommendation The authors suggest targeted modulation of sink phloem development to improve crop performance.
