      rice.

AB  - Root system architecture is very important for plant growth and crop yield. It is 
      essential for nutrient and water uptake, anchoring, and mechanical support. Root 
      growth angle (RGA) is a vital constituent of root system architecture and is used 
      as a parameter for variety evaluation in plant breeding. However, little is known 
      about the underlying molecular mechanisms that determine root growth angle in 
      rice (Oryza sativa). In this study, a rice mutant large root angle1 (lra1) was 
      isolated and shown to exhibit a large RGA and reduced sensitivity to gravity. 
      Genome resequencing and complementation assays identified OsPIN2 as the gene 
      responsible for the mutant phenotypes. OsPIN2 was mainly expressed in roots and 
      the base of shoots, and showed polar localization in the plasma membrane of root 
      epidermal and cortex cells. OsPIN2 was shown to play an important role in 
      mediating root gravitropic responses in rice and was essential for plants to 
      produce normal RGAs. Taken together, our findings suggest that OsPIN2 plays an 
      important role in root gravitropic responses and determining the root system 
      architecture in rice by affecting polar auxin transport in the root tip.
