'冬枣'、枝条扭曲及恢复变异的SSR鉴定和枝叶特征
SSR Analysis and Characteristics of Branch and Leaf of Twisted Branch Mutant from'Dongzao'and Its Revertant
摘要
Abstract
'Dongzao'(Ziziphus jujuba cv.'Dongzao'),twisted branch mutant and its revertant are a set of mutation materials.The objective of this study was to identify these variants by SSR and explore the char-acteristics of leaf and branch of the twisted branch mutants based on morphological and anatomical obser-vation.Fifty-two band types were amplified by 37 pairs of SSR primers from the genomic DNA of'Dong-zao',twisted branch mutant and its revertant,but no differences among three materials were found.Leaf transverse diameter,leaf perimeter,leaf area,long thorn and short thorn length of twisted branch mutant and its revertant were significantly lower than those of'Dongzao'.Leaf thickness,upper epidermis thick-ness,palisade tissue thickness,the ratio of palisade thickness/spongy tissue thickness and leaf tissue com-pactness of the revertant were significantly higher than those of'Dongzao'and twisted branch mutant.Leaf main vein thickness,vessel area,vessel diameter and vessel wall thickness of'Dongzao'were signifi-cantly larger than those of the twisted branch mutant and its revertant.The genetic background of'Dong-zao',twisted branch mutant of'Dongzao'and its revertant was the same,yet the branch and leaf traits dis-tinctively varied in three materials.'Dongzao'and both mutants could be used as materials for exploration of twisted branch growth mechanism.关键词
