M.; Maucher, H.; Schneider, B.; Stenzel, I.; Wasternack, C.; Boland, W.; Coronalon: a powerful tool in plant stress physiology FEBS Lett. 563, 17-22, (2004) DOI: 10.1016/S0014-5793(04)00239-X
Coronalon, a synthetic 6‐ethyl indanoyl isoleucine conjugate, has been designed as a highly active mimic of octadecanoid phytohormones that are involved in insect and disease resistance. The spectrum of biological activities that is affected by coronalon was investigated in nine different plant systems specifically responding to jasmonates and/or 12‐oxo‐phytodienoic acid. In all bioassays analyzed, coronalon demonstrated a general strong activity at low micromolar concentrations. The results obtained showed the induction of (i) defense‐related secondary metabolite accumulation in both cell cultures and plant tissues, (ii) specific abiotic and biotic stress‐related gene expression, and (iii) root growth retardation. The general activity of coronalon in the induction of plant stress responses together with its simple and efficient synthesis suggests that this compound might serve as a valuable tool in the examination of various aspects in plant stress physiology. Moreover, coronalon might become employed in agriculture to elicit plant resistance against various aggressors.
Flores, R.; Delgado, S.; Gas, M.-E.; Carbonell, A.; Molina, D.; Gago, S.; De la Peña, M.; Viroids: the minimal non-coding RNAs with autonomous replication FEBS Lett. 567, 42-48, (2004) DOI: 10.1016/j.febslet.2004.03.118
Viroids are small (246–401 nucleotides), non‐coding, circular RNAs able to replicate autonomously in certain plants. Viroids are classified into the families Pospiviroidae and Avsunviroidae , whose members replicate in the nucleus and chloroplast, respectively. Replication occurs by an RNA‐based rolling‐circle mechanism in three steps: (1) synthesis of longer‐than‐unit strands catalyzed by host DNA‐dependent RNA polymerases forced to transcribe RNA templates, (2) processing to unit‐length, which in family Avsunviroidae is mediated by hammerhead ribozymes, and (3) circularization either through an RNA ligase or autocatalytically. Disease induction might result from the accumulation of viroid‐specific small interfering RNAs that, via RNA silencing, could interfere with normal developmental pathways.
