PbIAA26 plays an important role in pear floral induction
Auxin is one of the key hormones in regulating plant growth and development. AUX/IAA genes belong to the early auxin response gene, and little was known about the role in floral induction of perennial woody plants. In this study, an AUX/IAA gene gene31333, that was renamed PbIAA26, was concerned by analyzing the gene transcription level of leaves related to the signal of floral induction in pear. In addition, 30 AUX/IAA genes (PbIAAs) were identified in pear, which were unevenly distributed on 10 chromosomes and classified into eleven groups by phylogenetic tree. Scanning cis-elements of PbIAAs promoters laid the foundation for other researchers to study the expression of regulatory PbIAAs. The expression of PbIAAs were similar in short branch leaves and long branch leaves during floral induction, except for PbIAA26. Meanwhile, overexpression of PbIAA26 in Arabidopsis showed early flowering traits. This discovery proved that PbIAA26 plays an important role in pear floral induction.
期刊介绍:
Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
