Distribution of FISH oligo-5S rDNA and oligo-(AGGGTTT)3 in Hibiscus mutabilis L.

Abstract: Hibiscus exhibits high variation in chromosome number both within and among species. The Hibiscus mutabilis L. karyotype was analyzed in detail using fluorescence in situ hybridization (FISH) with oligonucleotide probes for (AG3T3)3 and 5S rDNA, which were tested here for the first time. In total, 90 chromosomes were counted in prometaphase and metaphase, and all exhibited similarly intense (AG3T3)3 signals at both ends. (AG3T3)3 showed little variation and thus did not allow discrimination among H. mutabilis … Show more

“…Several chromosome sizes of other woody plants have been published: 1.05–1.81 μm in L. lucidum , 1.12–2.06 μm in F. pennsylvanica , 1.50–2.32 μm in S. oblata [ 29 ], 0.97–2.16 μm in J. regia [ 31 ], 1.23–2.34 μm in Z. armatum [ 34 ], 1.07–2.41 μm in Ch. campanulatus [ 30 ], 1.82–2.85 μm in B. diaphana [ 28 ], 1.18–3.0 μm in H. mutabilis [ 32 ], 1–4 μm in Citrus species [ 39 ], and 4.03–7.21 μm in P. concolor [ 33 ]. The chromosome size in our study (0.89–3.03 μm) is close to that of H. mutabilis (1.18–3.0 μm).…”

“…(AG 3 T 3 ) 3 , a classic chromosome end marker, is typically located in the distal region of the chromosome in H. mutabilis [ 32 ], J. regia , J. sigillata [ 31 ], F. pennsylvanica , S. oblata , L. lucidum , L. × vicaryi [ 28 ], B. diaphana , and B. soulieana [ 28 ]. Other similar types of (T x A y G z ) n [ 49 ] have also been identified at each chromosome end in the woody plants C. sinensis × P. trifoliata [ 23 ], Citrus clementina Hort.…”

“…The use of oligonucleotide systems enabled the first comprehensive cytogenetic analysis of Bletilla in the genomics era. A combination of 5S rDNA, and (AG 3 T 3 ) 3 probes has been used in Hibiscus mutabilis L. [37], Hippophae rhamnoides L. [38], Chimonanthus campanulatus R. H. Chang & C. S. Ding [39], Juglans regia L. and J. sigillata Dode. [40].…”
