體細胞雜交(somatic hybridization)是一種通過人工方法将不同物種的體細胞融合形成雜交細胞的技術,主要用于植物遺傳改良和種質資源創新。該技術通過去除細胞壁獲得原生質體,利用化學融合劑(如聚乙二醇)或物理方法(如電融合)促使不同來源的細胞膜融合,最終再生出具有雙親遺傳特性的雜種植株。
其核心應用包括:
該技術被中國農業科學院應用于柑橘類作物育種,成功獲得抗黃龍病的雜種材料。美國農業部研究顯示,體細胞雜交可縮短育種周期,特别適用于多年生木本植物改良。
“Somatic hybridization”(體細胞雜交)是生物學中的一項重要技術,其核心含義和特點如下:
指通過人工方法将不同物種或同種生物不同類型的體細胞(如去除細胞壁的原生質體)進行融合,形成雜合細胞的過程。該技術屬于無性繁殖範疇,可繞過傳統生殖隔離,實現遠緣物種間的基因交流。
傳統雜交依賴生殖細胞(如花粉與卵細胞結合),而體細胞雜交直接操作體細胞,突破有性生殖限制。例如,馬鈴薯與番茄的體細胞雜交曾産生“番茄薯”這一新物種。
如需更詳細的技術流程或案例,可參考生物學教材或專業文獻(如、6的細胞融合原理)。
