Chromosoma | 1950

Chromosome studies on Teillium Kamtschaticum Pall. and its allies. XXII. critical evidence of the spiral theory of crossing-over

Hajime Matsuura

SummaryIt was demonstrated that actual breaks and reunions of chromatids occur regularly within meiotic chromosomes at the first metaphase. These breaks are inferred to have originated from the parallelization of the relational spiral and to give rise to crossing-over, as predicted earlier (Matsuura, 1940).

THE EFFECT OF LOW TEMPERATURE TREATMENT ON MEIOTIC CHROMOSOMES IN TRILLIUM KAMTSCHATICUM PALL

I-Min Liu; Hajime Matsuura

オオバナノエンレイソウの還元分裂の全期間を低温処理 (0°C) した結果, 次の事柄が観察された.1) 第一中期における介在キアズマ頻度が, 対照区に比べて著しく増加した. そして染色体腕別でのその頻度は, 長さに従って増加率が大であった.2) 染色体の異常としては, 第一中期において一価染色体, 染色体断片及びキアズマ切断が多数観察された. なお後期において出現した染色体橋は, 明らかにキアズマ切断によるものであった.介在キアズマの増加, 及びキアズマ切断頻度と染色体橋の出現頻度の関係は, 新二面説にもとずいて説明した.
