High-Throughput Sequencing Reveals New Viroid Species in in Mexico.

In the main cactus pear ()-producing region in the State of Mexico, fruit production occupies the largest cultivated area with 15,800 ha, while 900 ha are cultivated for edible young pads ("nopalitos") which are consumed as vegetables. Two composite samples consisting of cladodes of plants for fruit production ( = 6) and another of "nopalitos" ( = 6) showing virus-like symptoms were collected. Both sample sets were subjected to high-throughput sequencing (HTS) to identify the viruses and viroids.
