The MADS-box family of transcription factors has been defined on the basis of primary sequence similarity amongst numerous proteins from a diverse range of eukaryotic organisms including yeasts, plants, insects, amphibians and mammals. The MADS-box is a conserved motif found within the DNA-binding ...
)摘 要:M I K C 是MA D S -b o x 蛋白家族中一类保守的转录因子家族,参与调控植物的开花时间和花器官发育㊂通过对黑麦M I K C 基因家族的分析,为研究黑麦各时期组织器官的功能奠定基础㊂利用P F a m 和B L A S T P 两种方法确定黑麦M I K C 家族共47个蛋白序列,将以上蛋白序列利用T B t...
box family gene,the genome-wide of beet MADS-box geneswere first identified by bioinformatics,and chromosomal localization,phylogenetic relationship,gene structure,conserveddomain,expression pattern and proteins function connections were predicted and analyzed. The results showed that therewere 34 MADS-box ...
Protein-protein interactionsPlant developmentFunctional edundancyTranscription factors are key regulators of plant development. One of the major groups of transcription factors is the MADS-box family, of which at least 80 members are encoded in the Arabidopsis genome. In this study, 23 members of ...
“We exploited a hidden Markov model that produces a profile out of a multiple sequence alignment. A profile for MADS-box proteins was built to screen the Arabidopis genome to identify new members of this family. Only hits with a E value of <1 were considered to be members of the family...
