| phenylpropanoid amides of serotonin accumulate in witches' broom diseased bamboo. | aciculosporium take (ascomycota; clavicipitaceae), causes the witches' broom disease in bamboo, particularly phyllostachys bambusoides. since it was observed that endogenous indole-3-acetic acid is reduced in the twigs of the diseased bamboo, the symptoms (bushy appearance) may be induced by reduction in auxin levels. furthermore, two indolic compounds accumulated in diseased twigs, these being identified as n-p-coumaroylserotonin and n-feruloylserotonin by lc-ms, 1h nmr and 13c nmr spectroscopi ... | 2003 | 14561512 |
| mechanisms of bamboo witches' broom symptom development caused by endophytic/epiphytic fungi. | aciculosporium take causes continuous shoot growth but maintains normal leaf-arrangement and branching patterns in the host plant, which eventually resulting in witches' broom disease of bamboo. an in situ hybridization technique with a species-specific oligonucleotide probe was recently used to demonstrate that endophytic mycelia of a. take is predominantly distributed in the intercellular spaces of the shoot apical meristem of the host. endophytic hyphae in meristematic tissues, which may prod ... | 2010 | 20118669 |
| specific in situ visualization of the pathogenic endophytic fungus aciculosporium take, the cause of witches' broom in bamboo. | the endophytic fungus aciculosporium take (ascomycota; clavicipitaceae) causes continuous shoot growth in bamboo. the colonized shoot eventually results in witches' broom formation but maintains normal leaf arrangement and branching pattern. to analyze the mechanism of well-regulated symptom development, the location of the fungal endophytic hyphae in host tissues was visualized. a colorimetric in situ hybridization technique using a species-specific oligonucleotide probe targeting the 18s rrna ... | 2009 | 19465522 |
