Rapid plant regeneration from Gerbera jamesonii Bolus callus cultures
A high frequency shoot organogenesis and plant establishment protocol has been developed for Gerbera jamesonii from ex vitro leaf derived callus. The optimal callus was developed on Murashige and Skoog (MS) basal medium supplemented with 0.4 mg L 6-benzylaminopurine (BAP), 4.0 mg L -naphthalene acetic acid (NAA) and 3% (w/v) sucrose. Two callus types differing in their structures and growth rat...
متن کاملDraft genome sequence of the New Jersey aster yellows strain of ‘Candidatus Phytoplasma asteris’
The NJAY (New Jersey aster yellows) strain of 'Candidatus Phytoplasma asteris' is a significant plant pathogen responsible for causing severe lettuce yellows in the U.S. state of New Jersey. A draft genome sequence was prepared for this organism. A total of 177,847 reads were assembled into 75 contigs > 518 bp with a total base value of 652,092 and an overall [G+C] content of 27.1%. A total of ...
متن کاملThe phytoplasma associated with ash yellows and lilac witches'-broom: 'Candidatus phytoplasma fraxini'.
Phytoplasmas associated with the plant diseases ash yellows (AshY, occurring in Fraxinus) and lilac witches'-broom (LWB, occurring in Syringa) represent a putative species-level taxon. Phytoplasmal DNA from 19 ash or lilac sources across the known geographic range of AshY (71-113 degrees W) was examined to determine if AshY and LWB phytoplasmas are a coherent group, if variability exists in bot...
متن کامل"Candidatus phytoplasma australiense," a new phytoplasma taxon associated with Australian grapevine yellows.
A phytoplasma was detected in naturally diseased 'Chardonnay' grapevines exhibiting symptoms of Australian grapevine yellows disease. The use of PCR designed to amplify phytoplasma DNA resulted in detection of phytoplasma DNA in all of the diseased plants examined; no phytoplasma DNA was detected in healthy seedling grapevines. The collective restriction fragment length polymorphism (RFLP) patt...
متن کاملRapid in vitro regeneration of Gerbera jamesonii (H. Bolus ex Hook. f.) from different explants
Rapid in vitro multiplication of shoots has been described using capitular sections and leaf explants in Gerbera jamesonii. Three types of basal media regimes were used including MS and two of its modified forms⎯MSI and MSA. Shoot induction was achieved on all three regimes but MSI medium supplemented with Kn (4 mg/l) and IAA (0.5 mg/l) was ideal for shoot bud initiation (8-11) from capitular s...
