Linear characterization of chromosomes in two species of family Euphaeidae (Odonata: Zygoptera)
Gurinder Kaur Walia, Neha Katnoria
Chromosome complement and meiotic behavior of chromosomes in two species of family Euphaeidae have been described by conventional staining, C- banding, silver nitrate staining and sequence specific staining. Anisopleura lestoides reveals two complements n=12 (without m chromosomes) and n=13 (with m chromosome), while Bayadera indica possess n=13m. In Anisopleura lestoides all the autosomal bivalents including m bivalent are showing terminal C-bands and NOR bands. Whereas in Bayadera indica, terminal C-bands on both ends in 9 autosomal bivalents and C-bands on one side in 3 bivalents, whereas terminal NOR bands are present in 10 autosomal bivalents, 1 NOR band on one side in 1 bivalent, m bivalent is C-negative and NOR-negative. X chromosome is C-positive and NOR rich in both the species. In the sequence specific staining, two autosomal bivalents show both CMA3 and DAPI bright signals and remaining bivalents including m bivalent and X chromosome possess CMA3 bright and DAPI dull regions in Anisopleura lestoides, while all the chromosomes show both DAPI and CMA3 bright signals in Bayadera indica.
