A study of the molecular structure of lily purple sub-room formation.

Recently, the lily research group of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences revealed the key mechanism of lily purple sub-room formation.
recently published online in the International Journal of Molecular Sciences.
lily is an important ornamental, edible and medicinal plant.
Its ornamental value is mainly to see flowers (flowers are filmed), but one of its flowers from flowering to flowering natural viewing period is usually only 10-20 days, lily-cut vase insertion life is generally 7-15 days, the group viewing period is usually about 1 month.
flowers, that is, the flowers are aging off, it lost its ornamental value.
In lily resources, a small number of lily species or varieties, such as Lilium nepalense D. Don and Asian lily cultivar Tiny Padhye, have purple or fuchsia sub-houses, and when petals fall off, the purple sub-houses of these varieties puff up to form fruit, with good viewing effect and up to 2-3 months of fruit-watching period.
red-purple lily houses and fruits can form a new lily viewing value, if this ornamental nature can be extended to more lily varieties, will break through the existing lily limited to ornamental flowers (pieces) this limitation.
the study used a combination of anatomy, metabolomics, comparative transcriptomics and molecular biology to study the molecular structure of lily purple sub-room formation.
color pigment of the purple sub-room is the main component of the car chrysanthemum-3-scented glycoside, and mainly accumulated in the sub-room wall under the first layer of cells.
expression spectrum suggests that the co-expression of all structural genes (except LhANS) involved in the anthophysine synthesis path pathline in the purple sub-room is a key mechanism for the formation of the purple sub-room.
addition, the study found that LhMYB12-Lat, an important regulatory factor for controlling anthyanin glycoside synthesis in lily petals, also plays an important role in regulating antholine synthesis in sub-rooms.
