Latest Patents

Gonsalves holds a patent for a new and distinct variety of plum named 'HoneySweet'. This transgenic plum is characterized by the presence of the plum pox virus coat protein gene, along with genes for kanamycin resistance (NPTII) and β-glucuronidase (GUS). The introduction of the plum pox virus coat protein transgene imparts a high level of resistance to the plum pox virus. In field tests, 'HoneySweet' has demonstrated immunity to the transmission of the plum pox virus by natural aphid vectors. When inoculated with the plum pox virus, 'HoneySweet' supports only a very low level of the virus and remains symptomless or exhibits only transient, mild symptoms. The fruit of 'HoneySweet' is large, sweet, firm, and visually appealing. The tree itself is productive and vigorous, exhibiting an upright growth habit. Gonsalves has 1 patent to his name.
