Abstract
|
|
|
|
We used petiole/leaf cuttings from potato (Solanum tuberosum L.) to study the effect of plant hormones on expression of the vegetative MADS-box gene, POTM1-1. Transcript levels were constitutive after treatments with exogenous ABA, GA_3, methyl jasmonate (MeJa), and NAA. However, transcripts amounts were reduced when tissues were treated with BA. High levels of cytokinin disrupted apical dominance and promoted axillary-bud formation. Therefore, based on these results, the POTM1-1 gene may conceivably be involved in maintaining the proper development of vegetative axillary meristems.
