Two-dimensional spreads of synaptonemal complexes from solanaceous plants. V. Tomato (Lycopersicon esculentum) karyotype and idiogram

Abstract

We used a hypotonic bursting technique to spread synaptonemal complexes (SCs) from tomato primary microsporocytes. Based on these spreads, we have prepared a karyotype and an idiogram for tomato SCs. Each SC was related to its corresponding chromosome by observing SCs from tomatoes that were trisomic for each chromosome. We have compared this SC karyotype with previously published pachytene chromosome karyotypes for tomato.Key words: synaptonemal complex, tomato, karyotype, idiogram.
