Strictosidine activation in Apocynaceae: towards a "nuclear time bomb"? [PDF]

open access: yes, 2010
Background The first two enzymatic steps of monoterpene indole alkaloid (MIA) biosynthetic pathway are catalysed by strictosidine synthase (STR) that condensates tryptamine and secologanin to form strictosidine and by strictosidine β-D-glucosidase (SGD ...

Pangenome analysis reveals the genetic mechanism underlying high‐altitude adaptation in Qinghai–Xizang (Tibet) Plateau Rhododendron

open access: yesJournal of Integrative Plant Biology, EarlyView.
Pan‐genome analysis reveals that high‐altitude Rhododendron species resist alpine cold stress by rapidly sensing and engaging the chilling response pathway and genes that directly and indirectly protect the plant from UV radiation. Heritable genomic features such as long terminal repeats contribute to the adaptive diversification of Rhododendron ...

Photoactivated [3+2] Addition of 6,7--angustilobine B to Fullerene [C]

open access: yesNatural Product Communications, 2012
A synthesis of a new alkaloid-fullerene conjugate ( 1 ) is reported. The reaction was carried out by photoinduced [3+2] cycloaddition of the Alstonia indole alkaloid, 6,7- seco -angustilobine B ( 2 ), to fullerene[C 60 ] ( 3 ) under aerobic conditions ...

Benzoxazinoid‐mediated microbiome feedbacks enhance Arabidopsis growth and defence

open access: yesNew Phytologist, EarlyView.
Summary Plants modulate their surrounding microbiome via root exudates and such conditioned soil microbiomes feed back on the performance of the next generation of plants. How plants perceive altered soil microbiomes and modulate their performance in response to such microbiome feedbacks, however, remains largely unknown.
