Phytuberol

Phytuberol (2 mL l^-1 10% (w/v) Rhizoctonia bataticola fungal elicitor + 100 mg l^-1 β-cyclodextrin; 48 h) production is induced in Solanum tuberosum hairy root cultures, with peak production of ~40 μg g^-1 dry wt achieved under these conditions^[1].
Phytuberol (2 days after inoculation) accumulation is induced by inoculation with Pseudomonas solanacearum U-7 in Burley 21 and Mito 3 tobacco callus (3.83 μg/g dry wt and 1.15 μg/g dry wt, respectively), but not in Bright Yellow 4 or Coker 319 tobacco callus^[2].
Phytuberol (4 days after inoculation; 3-6 weeks post-transplant growth period) accumulation induced by Pseudomonas solanacearum U-7 in Burley 21 tobacco callus is stable at ~1.6-1.8 μg/g dry wt in 3-5-week-old tissues, but drops to a trace level in 6-week-old tissues^[2].
Phytuberol (0 to 4 days after inoculation) accumulation in Burley 21 tobacco callus inoculated with Pseudomonas solanacearum U-7 increases over time, reaching its maximum 4 days after inoculation^[2].
Phytuberol (4 days after inoculation) accumulation in Burley 21 tobacco callus is induced to high levels (6.7-6.8 μg/g dry wt) by inoculation with Pseudomonas solanacearum strains (M23R and U-7), while inoculation with Pseudomonas syringae pv. tabaci strains (6602 and 7246) induces low phytuberol accumulation (0.24-0.41 μg/g dry wt)^[2].
Phytuberol (36-84 h) accumulates to increasing levels in Ethrel-treated Kennebec potato tuber slices inoculated with incompatible race 4 of Phytophthora infestans, reaching 37 μg/g fresh weight after 84 hours of incubation^[3].
Phytuberol (72 h) accumulates to 43 μg/g fresh weight in Ethrel-treated Kennebec potato tuber slices and 95 μg/g fresh weight in Ethrel-treated Russet Burbank potato tuber slices inoculated with Helminthosporium victoriae after 72 hours of incubation^[3].
Phytuberol (72 h) accumulates to 41 μg/g fresh weight in Ethrel-treated Kennebec potato tuber slices and 67 μg/g fresh weight in Ethrel-treated Russet Burbank potato tuber slices inoculated with Helminthosporium carbonum after 72 hours of incubation^[3].
Phytuberol (36-84 h) accumulates to increasing levels in Ethrel-treated Kennebec and Russet Burbank potato tuber slices treated with autoclaved cell-free sonicates of Phytophthora infestans race 4, reaching 17 μg/g and 14 μg/g fresh weight respectively after 84 hours of incubation^[3].
Phytuberol (72 h) accumulates to 25 μg/g fresh weight in Ethrel-treated Kennebec potato tuber slices treated with autoclaved cell-free sonicates of Pythium aphanidermatum after 72 hours of incubation^[3].
Phytuberol (72 h) accumulates to 23 μg/g fresh weight in Ethrel-treated Kennebec potato tuber slices treated with autoclaved cell-free sonicates of Achlya flagellata after 72 hours of incubation^[3].
Phytuberol accumulates in Ethrel-treated Kennebec potato tuber slices treated with autoclaved cell-free sonicates of Phytophthora infestans race 4 at 14°C, 19°C, and 25°C, with maximum accumulation (31 μg/g fresh weight) occurring at 19°C; no phytuberol is detected at 30°C or 36°C^[3].
Phytuberol (100 μliters/liter; 72 h) accumulates to 52 μg/g fresh weight in Kennebec potato tuber slices treated with autoclaved cell-free sonicates of Phytophthora infestans race 4 and exposed to 100 μliters/liter ethylene after 72 hours of incubation^[3].
