Other claims from this paper (10)
- Intervention effect RY2 had higher P acquisition efficiency than RY5 under the same P treatment.
- Observation P utilization efficiency was similar between the two stylo cultivars.
- Observation RY2 had better root growth performance than RY5 at low P.
- Observation RY2 had higher leaf and root APase activities than RY5.
- Observation RNA-seq of RY2 roots revealed 8,348 genes differentially expressed under P deficient and sufficient conditions.
- Observation Many Pi starvation regulated genes in stylo are associated with P metabolic process, protein modification process, transport and other metabolic processes.
- Observation Differentially expressed genes involved in Pi uptake and Pi homeostasis were identified, including genes for a Pi transporter, purple acid phosphatase and MATE.
- Observation Genes related to transcription factors and regulators of Pi signaling were regulated by P deficiency in stylo roots.
- Mechanism Low-P tolerance in stylo is probably manifested through regulation of root growth, Pi acquisition, cellular Pi homeostasis and the Pi signaling pathway.
- Recommendation The identified genes may be used to design breeding strategies for P-efficient stylo cultivars grown on acid soils in the tropics.
