中文拼音 [jíxiǎotóngpēi]
極小同胚
英文
minimal homeomorphism-
A sufficient condition is given for a homeomorphism with the the average shadowing property to be minimal. in section 3. 3, we prove that if / has the potp and is equicontinuous, then / has the limit shadowing property
2節討論了平均跟蹤與偽軌跟蹤的關系，並給了有平均跟蹤的自同胚是極小的一個充分條件。Detailly, it was ( l ) to isolate and construct high efficiency expression vector of rice starch branching enzyme gene sbe2b and ( 2 ) to establish a high - effecient rice transformation system. total rna was extracted from maize endosperm 15dap ( days after pollination ). and cdna of sbe2b was obtained through rt - pcr. sequencing result showed that the full length cdna was 2. 4kbp, coding for 800 amino acids, with estimated mw 93kd
本研究從授粉15天左右的玉米胚乳中提取了總rna ，採用rt - pcr方法，克隆了玉米胚乳的澱粉分支酶基因sbe2b ，測序結果表明，玉米胚乳sbe2b的cdna全長為2 . 4kb ，編碼800個氨基酸，推測的氨基酸的分子量為93000d ，該序列與genbank中登錄號為af072725的玉米sbe2b的cdna序列有98的同源性，與水稻、大麥、小麥等禾本科植物的有關澱粉分支酶的dna序列都有極高的同源性。
