Gene Details:

• Gene ID: Sb03g006765
• Gene Symbol: SbPSTOL1
• Gene Name: PHOSPHORUS-STARVATION TOLERANCE1
• Genome:
• Species: Sorghum bicolor

Functional Descriptions:

• SbPSTOL1 genes colocalized with quantitative trait loci for traits underlying root morphology and dry weight accumulation under low P via linkage mapping.
• Single-nucleotide polymorphisms (SNPs) within PSTOL1 homologs in sorghum, collectively designated SbPSTOL1, were significantly associated with grain yield under low-P conditions and also root morphology and root system architecture (RSA) traits phenotyped from hydroponically grown plants.
• Our results indicate that SbPSTOL1 homologs have the ability to enhance P uptake and sorghum performance in low-P soils by a mechanism related not only to early root growth enhancement, as was the case for rice OsPSTOL1, but also by modulating RSA.
• This study indicates that multiple SbPSTOL1 genes have a more general role in the root system, not only enhancing root morphology traits but also changing root system architecture, which leads to grain yield gain under low-P availability in the soil.
