The draft genome of Xylella fastidiosa subsp. pauca strain 11399, a transformable citrus-pathogenic strain, is reported here. The 11399 genome size is 2,690,704 bp and has a G+C content of 52.7%. The draft genome of 11399 reveals the absence of four type I restriction-modification system genes.

Yolk/shell capsules containing a volume/hydrophobicity transformable core and an ultra-thin silica shell have been prepared. When an external magnetic field induced the temperature, the cores exhibit a significant triggering size shrinkage and the diameter decreases more than 10 times, causing solid shells destruction and physical collapse, leading to drug burst release.
