Pollination biology of Aristolochia tagala, a rare species of medicinal importance [PDF]
, 2006 Floral phenology, pollination biology and breeding system were studied in Aristolochia tagala Cham (Aristolochiaceae) grown under ex situ conditions. The flower exhibits structural features typical of fly-trap mechanism described for other Aristolochia ...

Evolutionary Constraints to Viroid Evolution [PDF]
, 2009 We suggest that viroids are trapped into adaptive peaks as the result of adaptive constraints. The first one is imposed by the necessity to fold into packed structures to escape from RNA silencing.

Time-Course Microarray Analysis Reveals Differences between Transcriptional Changes in Tomato Leaves Triggered by Mild and Severe Variants of Potato Spindle Tuber Viroid [PDF]
, 2018 Viroids are small non-capsidated non-coding RNA replicons that utilize host factors for efficient propagation and spread through the entire plant. They can incite specific disease symptoms in susceptible plants.
