Viroids are plant pathogens that consist of a short stretch (a few hundred nucleobases) of highly complementary‚ circular‚ single-stranded RNA without the protein coat that is typical for viruses.[1] The smallest discovered is a 220 nucleobase scRNA (small cytoplasmic RNA) associated with the rice yellow mottle sobemovirus (RYMV).[2] In comparison‚ the genome of the smallest known viruses capable of causing an infection by themselves are around 2kilobases in size. The human pathogen hepatitis D is

A plants volatile organic compound (VOC) composition is the hand that swats unwanted visitors‚ welcomes visitation from much needed pollinators‚ and the substantial determinant in a plants identity and overall evolutionary fitness within the plant community. Understanding the mechanics of volatile formation is essential in interpreting their importance in plant life‚ and in plant-animal interactions. A huge allocation of energy is assumed to be given to the production of volatiles‚ and is therefore
