Plant tissue culture includes a wide range of techniques: protoplast, cell, anther, callus, meristem and organ culture, all having one common factor: the growth of vegetative material in an aseptic environment; i,e., the sterilized culture medium in test tubes. In spite of the fact that several o...

Methods of vegetative reproduction are discussed using the results obtained with cassava and potato. Results of clone cleaning by heat therapy and in vitro meristem culture are given. Two methods for rapid cassava multiplication are proposed: by sprouts from cuttings and single leaf cuttings, whi...

We report the first identification of novel viruses, and sequence of an entire viral genome, by a single step of high-throughput parallel sequencing of small RNAs from diseased, as well as symptomless plants. Contigs were assembled from sequenced total siRNA from plants using small sequence assem...

With the aim to find new sources of resistance to rice hoja blanca (white leaf) disease, transmitted by the insect Tagosodes orizicolus, 660 genotypes were evaluated under greenhouse and field conditions. Seven resistant genotypes were identified, and genomic studies were performed to demonstrate...
