Hexyl gallate for the control of citrus canker caused by Xanthomonas citri subsp citri

MicrobiologyOpen, Volume 9, Issue 9, September 2020., 2020
We evaluated hexyl gallate (G6) as an alternative to copper compounds for citrus plant protection. G6 was able to protect citrus nursery trees against Xanthomonas citri infection, and it is safe for tissue culture cell lines. This study demonstrated that G6 is a promising candidate for the development and use in citrus canker management.

Rescue of Citrus sudden death‐associated virus in Nicotiana benthamiana plants from cloned cDNA: insights into mechanisms of expression of the three capsid proteins

Molecular Plant Pathology, Volume 20, Issue 5, Page 611-625, May 2019., 2019
Summary Citrus sudden death‐associated virus (CSDaV) is a member of the genus Marafivirus in the family Tymoviridae, and has been associated with citrus sudden death (CSD) disease in Brazil. Difficulties in the purification of CSDaV from infected citrus plants have prevented progress in the investigation of the role of this virus in CSD and an ...
