Dormancy-associated MADS-box genes and microRNAs jointly control dormancy transition in pear (Pyrus pyrifolia white pear group) flower bud.
Bud dormancy in perennial plants is indispensable to survival over winter and to regrowth and development in the following year. However, the molecular pathways of endo-dormancy induction, maintenance, and release are still unclear, especially in fruit crops. To identify genes with roles in regulating endo-dormancy, 30 MIKC(C)-type MADS-box genes were identified in the pear genome and character...
متن کاملPhysiological differences between bud breaking and flowering after dormancy completion revealed by DAM and FT/TFL1 expression in Japanese pear (Pyrus pyrifolia).
The regulatory mechanisms underlying bud breaking (scale leaf elongation) and flowering in the lateral flower buds of Japanese pear (Pyrus pyrifolia Nakai 'Kosui') are unknown. To more fully characterize these processes, we treated pear trees with different amounts of chilling initiated at different times. Chilling for ∼900 h at 6 °C always induced bud breaking (scale elongation in ≥70% lateral...
متن کاملAbscisic Acid (ABA ) Promotes the Induction and Maintenance of Pear (Pyrus pyrifolia White Pear Group) Flower Bud Endodormancy
Dormancy is an adaptive mechanism that allows temperate deciduous plants to survive unfavorable winter conditions. In the present work, we investigated the possible function of abscisic acid (ABA) on the endodormancy process in pear. The ABA content increased during pear flower bud endodormancy establishment and decreased towards endodormancy release. In total, 39 putative genes related to ABA ...
متن کاملTranscriptome analysis of Japanese pear (Pyrus pyrifolia Nakai) flower buds transitioning through endodormancy.
The transcriptomes of endodormant and ecodormant Japanese pear (Pyrus pyrifolia Nakai 'Kosui') flower buds were analyzed using RNA-seq technology and compared. Among de novo assembly of 114,191 unigenes, 76,995 unigenes were successfully annotated by BLAST searches against various databases. Gene Ontology (GO) enrichment analysis revealed that oxidoreductases were enriched in the molecular func...
متن کاملEffect of maleic hydrazide on endogenous cytokinin contents in lateral buds, and its possible role in ̄ower bud formation on the Japanese pear shoot
In order to elucidate the role of maleic hydrazide (MH, 1,2-dihydro-3,6-pyridazinedione; coline salt) in increasing ̄ower bud formation on the Japanese pear, the effect of MH on cytokinin contents in the lateral buds of Japanese pear shoots were investigated. Foliar application of MH at 2600 mg lÿ1 increased zeatin, zeatinriboside, and isopentenyladenine levels in lateral buds though isopenteny...
