異なるプラスミドが宿主に与えるコストの評価

片岡 大亮1, 道羅 英夫2, 鈴木 智大2, 金原 和秀1, 新谷 政己1 1静大院・総合科技・工, 2静大，グリーン研 【目的】プラスミドは種々の微生物間を接合伝達によって伝播可能な遺伝子の運び手であり，微生物の急速な進化・適応に寄与する．プラスミドがどのような微生物に，どの程度の頻度で伝播するのか，またその宿主にどの程度の負荷を与えるのかという情報は，微生物生態を理解する上で重要である．我々は，IncP-1群に属するプラスミドpBP136の伝播可能な宿主の種類や伝達頻度を比較してきた．その過程で同一の菌株Pseudomonas putida mt-2株に由来

網羅的遺伝子発現解析を用いた増殖に伴う大腸菌の比重多様性の解明

佐々木 謙1,2, 水野 敬文2, 関口 勇地2, 青柳 秀紀1, 野田 尚宏2 1筑波大院・生命環境, 2産総研・バイオメディカル 　対数増殖期の細菌は、培地中の栄養源の枯渇や分泌物質の蓄積といった生育環境の変化を理由に定常期へと移行する。その移行の際には、細胞の小型化、細胞の球形化、核様体の凝集、細胞壁組成の変化などが起こることが一般的に知られているが、大腸菌では比重の多様性が変化することも知られている。既往の研究で、対数増殖期と定常期の大腸菌（単一株）培養液をPercoll密度勾配遠心したところ、各増殖期において比重が明確に異なる複数の細胞集団が生じることが
