Germplasm Phenotype:

• SALK_111625C  — The ren1-3 pollen grains sometimes develop moderately bublous tubes, but they are fertile (unlike the sterile pollen grains caused by the more severe alleles ren1-1 and ren1-2).
• ren1-1  — The sterile ren1-1 pollen grains from this heterozygous plant germinate precociously at a higher rate than wild type pollen tubes, and they often form bulbous tubes that are incapable of adhering to or entering the stigma. The domain of ROP1 expression in the pollen tubes is expanded in these mutants. GFP:RIC4, which binds to the PM-localized active form of ROP1, is also visible across an abnormally broad area in the pollen tube tips of ren1-1 mutants.
• ren1-2  — The sterile ren1-2 mutant pollen grains from this heterozygous plant germinate precociously at a higher rate than wild type pollen tubes, and they often form non-functional bulbous tubes.
