Title : Genome-wide Characterization and Analysis of MADS-boxTranscription FactorGene FamilyRelated toFlower Induction in Pineapple (Ananascomosus)
Abstract:
MADS-box transcription factors are vital regulators participating in plant growth and development, but a little information is available regarding the MADS-box gene family in Pineapple (Ananascomosus), a very important tropical fruit in the world. Herein, 40 MADS-box genes were identified in Pineapple, and could be divided into two types, in which 26 AcMADSs were grouped in type II (MIKC), while 14 in type I. Transcriptome analysis of pineapple buds revealed that many MADS-box genes were activated by ethephon after 1 d treatment. Some candidate AcMADSs participating in flowering were identified for further functional characterization in pineapple, and all data provide new insight into AcMADS-mediated flowering related to ethylene in Pineapple.
