The floral primordium is initially circular, along with the edge of which slight concaves occur. The outmost whorl of tepal primordia arises as a result of apical meristem division and the floral primordium then is in the shape of triangle. Two further whorls of tepal primordia arise in spiral acropetal sequence and are alternately arranged. When the innermost whorl of tepal primordia is at the late developmental stage, the foremost stamen primordia arise almost simultaneously in spiral acropetal succession and all of the stamen primordia are ultimately arranged in a triangle-cone form. Late in stamen primordium development, carpel primordia arise as same as the young stamen primordia and grow laterally. Grooves are present on the adaxial side of each carpel and develop into ventral sutures gradually closing up.
观光木的花原基最初为近圆形,随着顶端分生组织的活动,花原基边缘处出现浅凹,形成第一轮花被片原基,此时,花原基呈三角形排列,后两轮花被片原基依次发生,与前一轮互生;在内轮花被片发生的后期,最初几枚雄蕊原基几乎同时出现,呈螺旋状向顶发生,最后排列成三角圆锥状;雄蕊原基发育后期,心皮原基开始发育,形状与发育初期的雄蕊原基相似,随后心皮原基进行侧向生长,在近轴面出现浅凹,进而发育为凹槽,形成腹缝线,最后腹缝线完全愈合。

There are three copies of R fragment in the S mt-genome, and each copy contains two closely adjacent open reading frames: orf355 and orf77. Among these three copies two BamHI fragments were cloned, and the sequence analysis showed that cox1 and cox2 gene lies upstream of the R region in each fragment, respectively. However, they locate in different strands and head to head with R. In this study, we found that:(1) The expression of cox1 and cox2 is not affected by the transcription of R region;(2) The two copies of R region transcribe in large amount in the microspores, and produce transcripts of 1.6kb and 2.8kb, respectively, in the sterile microspores; However, the abundance of these two transcripts is reduced in the fertility restored microspores, realized through the mRNA decay, and this reduction occurs at the uninucleate microspore stage;(3) In the sterile microspores, the 5 terminus of the 1.6kb transcript contains a palindrome region that can fold into a stem-loop.
本研究发现:(1) cox1和cox2的转录没有受到R区转录的影响;(2)两个拷贝的R区在在不育花粉中高丰度表达,其转录本大小分别为1.6kb和2.8kb;而在育性恢复的花粉中,这两个转录本的丰度被大大降低,进一步分析表明这一结果是通过mRNA分子的降解途径来实现的,此降解过程发生在单核花粉期;(3)在不育花粉中,1.6kb转录本的5′末端具有一段可形成茎环结构的迴文对称序列,而在可育花粉中,其5′末端短缺了9个碱基;(4)在不育花粉和育性恢复的花粉中,R区转录本的加尾位点都集中位于一个3′茎环结构之后;(5)不管是在不育花粉还是育性恢复的花粉中,orf77区域内均在第52位和100位核苷酸处发生了不同频率的C向U的编辑,从而形成UGA终止密码;(6)不管是orf55-orf77的成熟转录本还是转录前体分子,都已被加上了Poly尾巴,表明已进入降解途径;在以上实验结果的基础上,本研究对S型CMS花粉育性的恢复机理进行了如下推测:在不育花粉和育性恢复的花粉中,orf77区域内均发生了终止编辑,即由RNA编辑产生了提前终止密码子。
