Floral transition in lisianthus (Eustoma grandiflorum)

Scientia Horticulturae, 2002
Abstract Floral transition was studied in lisianthus [Eustoma grandiflorum (Raf.) Shinn.] plants grown in a greenhouse at two planting times (winter and summer) under two photoperiod regimes: long day (LD) and short day (SD), 16 h/8 h and 8 h/16 h (light/dark), respectively.

Anthocyanin pigmentation of lisianthus flower petals

Plant Science, 1999
Abstract In most lisianthus flowers anthocyanin coloration occurs very late in petal development just preceding unfurling of the petals. We have developed through breeding several lisianthus lines in which coloration occurs at a very early developmental stage.

Cell wall sited flavonoids in lisianthus flower petals

Phytochemistry, 2000
Flavonoids are considered to be located predominantly in the vacuoles of epidermal cells and in the cuticular wax of terrestrial plants. However, recent reports have suggested that flavonoids may also reside elsewhere in the cells of green leaves. In the present study of lisianthus flower petals, it is demonstrated that ca.

Transformation of lisianthus (Eustoma grandiflorum)

Plant Cell Reports, 1997
Transformed plants from three cultivars of Eustoma grandiflorum (lisianthus) were produced by cocultivating young leaf pieces with Agrobacterium tumefaciens strain A722 containing the binary vectors pKIWI110 and pLN26. Both vectors contain the selectable marker gene for neomycin phosphotransferase II.

Transgenic Eustoma grandiflorum (Lisianthus)

2001
Lisianthus or prairie gentian [Eustoma grandiflorum (Griseb.) Shinn.] is a member of the family Gentianaceae and native to the prairies of the U.S.A. (Shinners 1957). A typical wild-type plant produces a single stem with a purple flower. Intensive breeding in Japan over the past 40 years has resulted in the generation of cut-flower varieties with ...

Somatic Embryogenesis in Lisianthus (Eustoma russellianum Griseb.)

2016
Somatic embryogenesis is, for the main floricultural crops, a promising system for commercial scale-up, providing cloned material to be traded as seedlings. Somatic embryos, having the contemporary presence of root apical meristem and shoot apical meristem, can be readily acclimatized.

MODIFYING LISIANTHUS TRAITS BY GENETIC ENGINEERING

Acta Horticulturae, 2001
The control of flowering time is an essential issue for most ornamentals. The molecular basis of this trait has been extensively studied in model plants, yielding useful information on the role of various genes which could potentially be used in heterologous systems.

Transformation in Eustoma grandiflorum (Lisianthus)

1993
Lisianthus (Eustoma grandiflorum (Griseb) Shinn.] is a gentian native to the central and southern United States (Bailey 1949, Shinners 1957). Due to its large flowers, long stems, and extended vase life, it is an increasingly popular cut flower. The typical wild plant has blue-purple flowers, but intensive breeding in Japan over the last 30 years has ...

Lisianthus Leaf Curl a New Disease of Lisianthus Caused by Tomato Yellow Leaf Curl Virus

Plant Disease, 1995
In 1992 viruslike symptoms appeared on lisianthus plants grown at different locations in Israel. The symptoms included distortion of the growing tips, cup-shaped leaves, and swelling of veins on the lower surface of the leaves. Plants infected at an early stage did not yeld flowers, but late infections did not impair flowering.
