Chloroplast DNA (cp) and nuclear ribosomal DNA (rDNA) variation was investigated in 45 accessions of cultivated and wild Manihot species. Ten independent mutations, 8 point mutations and 2 length mutations were identified, using eight restriction enzymes and 12 heterologous cpDNA probes from mung...

Similar to humans, plants are populated with different sets of microorganisms with potential roles on host and ecosystem functions. Endophytic microorganisms colonize root tissues inter- and/or intracellularly producing a wide range of compounds useful for plants growth as well as for protection ...
