In vitro pollen germination of wild type, atptr1-1, atptr5-1, atptr1-2 atptr5-1, and 35S:AtPTR5a. A, Pollen germination rate of wild type, atptr1-1, atptr5-1, atptr1-2 atptr5-1, and 35S:AtPTR5a. Pollen was germinated for 14 h on GM (Footitt et al., 2007) in the absence or presence of 20 or 100 μm of the toxic dipeptide Ala-Eth. Germination was defined as emergence of the pollen tubes. B, Germination and growth of pollen tubes of wild type, atptr1-1, atptr5-1, atptr1-2 atptr5-1, and 35S:AtPTR5a; bar = 25 μm. Germination and pollen tube growth of atptr1-2 and atptr5-2 mutants was comparable to results shown for atptr1-1 and atptr5-1, respectively (data not shown).
