Auxin involvement in tepal senescence and abscission in Lilium: a tale of two lilies.

Lombardi L, Arrom L, Mariotti L, Battelli R, Picciarelli P, Kille P, Stead T, Munné-Bosch S, Rogers HJ - J. Exp. Bot. (2014)

Bottom Line: For example, tepals of Lilium longiflorum wilt substantially, while those of the closely related Lilium longiflorum×Asiatic hybrid (L.A.) abscise turgid.There was a dramatic increase in auxin levels with senescence in L. longiflorum but not in Lilium L.A.Fifty auxin-related genes were expressed in early senescent L. longiflorum tepals including 12 ARF-related genes.

Relative expression of ARF-like genes by real time RT-PCR. Transcript levels of the ARF6/8-like gene (A, B) and the ARF7/19-like gene (C, D) in L. longiflorum (A, C) and Lilium L.A. (B, D) at the stages defined in Fig 1. Results are means±SE, n=10. Different letters indicate significant differences among stages as determined by one-way analysis of variance.

Figure 5: Relative expression of ARF-like genes by real time RT-PCR. Transcript levels of the ARF6/8-like gene (A, B) and the ARF7/19-like gene (C, D) in L. longiflorum (A, C) and Lilium L.A. (B, D) at the stages defined in Fig 1. Results are means±SE, n=10. Different letters indicate significant differences among stages as determined by one-way analysis of variance.

Mentions: The transcript level of the ARF6/8 homologue fell with tepal age in both lilies but with different patterns (Fig. 5A, B). In Lilium L.A., there was a peak in transcript level at FB, which then essentially disappeared at abscission; in L. longiflorum, the highest expression was in CB and expression then declined gradually.
