Limitations of Flow Cytometry in Detecting Aneuploids: Insights From Chromosome Doubling in Hemerocallis citrina

Ziyi Wang, Hanyan Liu, Yi Lv, Yike Gao et autres

ABSTRACT Flow cytometry is a commonly used method to test for chromosome doubling, but during the doubling of Hemerocallis citrina , it was found that flow cytometry sometimes failed to accurately detect aneuploidy and mixploidy in doubled seedlings. In this study, a …

The CONSTANS-like 2 Gene Serves as a Pivotal Regulator of Flowering in Hemerocallis

Chunjing Guan, Yike Gao, Ziyi Wang, Qixiang Zhang

Hemerocallis spp. exhibit distinct flower opening times, categorized into nocturnal and diurnal types. Previous studies have demonstrated that the circadian clock and CONSTANS (CO) genes play crucial roles in regulating flowering in Hemerocallis. However, the key genes that integrate flowering pathways remain …

FLOWERING LOCUS T homologue in reblooming bearded iris (Iris spp.) plays a role in accelerating flowering and reblooming

Zhuping Fan, Yike Gao, Chunjing Guan, Rong Liu et autres

Reblooming bearded iris (Iris spp.) could have two floral initiations and thus two blooming seasons annually. The previous transcriptome profiling has identified a homologue of FLOWERING LOCUS T (FT) as a candidate key gene of reblooming. To further verify its functions in …

Interfamily wide hybridization between daylily (Hemerocallis, Xanthorrhoeaceae) and lycoris (Lycoris, Amaryllidaceae)

Yi Lv, Yike Gao, Yuxuan Cui, Wang Ying et autres

Abstract Daylily (Hemerocallis) is a perennial with high ornamental value. It is difficult to obtain innovative daylily germplasm by conventional crossbreeding. To enrich the genetic variation of Hemerocallis, daylily was used as male parent to cross with lycoris (Lycoris). Artificial pollination and …

The Mechanism of Flower Opening and Closing Times Revealed By Transcriptome Profiling

Rong Liu, Chunjing Guan, Zhuping Fan, Liya Ding et autres

Abstract Background: Circadian clock precisely control flowers open and close at specific times of day responsive to the environment, providing advantages in reproduction and adaption. Flowers of Iris dichotoma and I. domestica are ephemeral and show single opening and closing which present …

To bloom once or more times: the reblooming mechanisms of Iris germanica revealed by transcriptome profiling

Zhuping Fan, Yike Gao, Yi Ren, Chunjing Guan et autres

Abstract Background The reblooming bearded iris (Iris germanica) can bloom twice a year, in spring and autumn. The extended ornamental period makes it more popular and brings additional commercial values. However, little is known about the reblooming mechanisms, making the breeding programs …
