Figure 5: Functional complementation of ptb1.
From: Natural variation in PTB1 regulates rice seed setting rate by controlling pollen tube growth
(a) Plant phenotype of ptb1. (b) Plant phenotype of the PTB1-transformed ptb1 plants (ptb1–PTB1). (c) Panicle phenotype of ptb1. (d) Panicle phenotype of the ptb1–PTB1 transgenic plants. (e) Co-segregation of the introduced PTB1 and the fertile panicle phenotype. The white lined box indicates that the transgenic plants were resistant to the herbicide Barstar (a Barstar resistance gene was placed in the T-DNA region of the pHB vector) and non-transformed plants remained sensitive. T1-S, Barstar-sensitive T1 plants; T1-R, Barstar-resistant T1 plants.
