Anthurium, transformation

Hui-chun Liu, Dan-qing Tian, Jian-xin Liu, Guang-ying Ma, Qing-cheng Zou, Zhu-jun Zhu
An 888-bp full-length ascorbate peroxidase (APX) complementary DNA (cDNA) gene was cloned from Anthurium andraeanum, and designated as AnAPX. It contains a 110-bp 5'-noncoding region, a 28-bp 3'-noncoding region, and a 750-bp open reading frame (ORF). This protein is hydrophilic with an aliphatic index of 81.64 and its structure consisting of α-helixes, β-turns, and random coils. The AnAPX protein showed 93%, 87%, 87%, 87%, and 86% similarities to the APX homologs from Zantedeschia aethiopica, Vitis pseudoreticulata, Gossypium hirsutum, Elaeis guineensis, and Zea mays, respectively...

KEY MESSAGE : There are multiple publications on Anthurium transformation, yet a commercial product has not been achieved. This may be due to use of non-optimum promoters here we address this problem. Different promoters and tissue types were evaluated for transient β-glucuronidase (GUS) expression in Anthurium andraeanum Hort. 'Marian Seefurth' following microprojectile bombardment. Plasmids containing the Ubiquitin 2, Actin 1, Cytochrome C1 from rice, Ubiquitin 1 from maize and 35S promoter from Cauliflower Mosaic Virus fused to a GUS reporter gene were bombarded into in vitro grown anthurium lamina, somatic embryos and roots...

The genetic basis of systemic resistance to bacterial blight disease (blight) of anthurium (Anthurium andraeanum) caused by Xanthomonas axonopodis pv. dieffenbachiae was investigated in progenies of 53 crosses involving 31 parent cultivars using segregation analysis. Inoculation of parents and progenies was achieved by injecting the petiole base of the most recent fully expanded leaf with 100 microl of 10(9) colony forming units per ml of the blight pathogen (strain X4gfp) transformed with the green fluorescent protein (GFP) gene...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
