According to the space - tim e maturation during the development of the vessel elements in primary vascular system : the vessel elememts of the cotyledons and the lower portion of cnz formed firstly , then downward hypocotyl - root zone , at length , the vessel elememts of the upper and middle portion of cnz and epicotyl - shoot region connected with each other , the result uphold the seedling partition model that divides seedling into cnz , hypocotyl - root region and epicotyl - shoot region 根據(jù)金魚草幼苗初生維管系統(tǒng)導(dǎo)管分子發(fā)育的時(shí)空性,即子葉和子葉節(jié)區(qū)下部導(dǎo)管分子先形成,然后向下形成下胚軸-根區(qū)的導(dǎo)管分子,最后子葉節(jié)區(qū)中、上部與上胚軸-苗區(qū)的導(dǎo)管分子再發(fā)生連接,據(jù)此支持將幼苗分為子葉節(jié)區(qū)、下胚軸-根區(qū)和上胚軸-苗區(qū)的幼苗分區(qū)模型。
The results showed that the vessel element did n ' t differentiate after the seeds had imbibied for 6 hours ; 6 hours after seeds germination , two loci ? ne below the middle portion of the cotyledon and the other in the lower portion of cotyledon - node zone ( cnz ) initiated the differentiation of vessel element simultaneously , then elongated towards the cotyledonary apex and hypocotyl - root region respectively ; eventually the two promoter loci began to interconnect through vessel elements 結(jié)果表明:種子吸漲6h ,未有導(dǎo)管分子的分化;種子萌發(fā)后6小時(shí)期間,自子葉中部偏下方和子葉節(jié)區(qū)下部的兩個(gè)位點(diǎn)同時(shí)啟動(dòng)導(dǎo)管分子的分化,并分別向子葉葉尖和下胚軸-根的方向延伸;爾后,在發(fā)生兩個(gè)啟動(dòng)位點(diǎn)之間發(fā)生導(dǎo)管分子的連接。
