the northwest highlands. Phytophthora infestans The JP-2 genotype - also known as SIB-1, a subpopulation of A1 with a IIa mitochondrial haplotype - was found here by Akino et al 2010, and is genetically close to European populations. It is shared with Japan, China, and Korea. TH-1 (in the Ia mtDNA haplotype, of the A2 mating type) is shared with southwest China and Nepal, as reported for samples from 1994-1997 by Guo et al 2010. The US-1 population - a subtype of A1 in the Ib mt haplotype - is shared with China, India, Nepal, Japan, Taiwan, and Vietnam. It is first known in Asia from a Thai sample from 1981, but not reported until Saville and Ristaino 2020. A2 was unknown here until a restriction fragment length polymorphism (TH-1) was found in a 1994 sample by Gotoh et al 2005. Other samples from the same year from Chiang Mai, analysed by Nishimura et al 1999, showed both A1 (specifically US-1) and A2 (specifically a metalaxyl-sensitive genotype) on potato, but only US-1 on tomato. Twenty-five samples from 2000-2002 were found (by Petchaboon et al 2014) to have RG57s that matched European populations of the IIa mtDNA haplotype, of the A1 mating type - another two being other A1s. They used Day et al 2004's nomenclature for this almost universal potato parasite lineage, calling it RF006. This result was confirmed by a pers. comm. from employees of Agriculture Victoria in 2020, who know it as the simple sequence repeat genotype EU 8 A1 from samples they have from 2009 from Thailand. This is probably the same lineage that was found in 2006-2009 samples and reported by Jaimasit and Prakob in 2010 - 117 of them all being A1, IIa. Their samples were mostly metalaxyl-sensitive but with some -intermediate and some -resistant. Rice production in Thailand represents a significant portion of the Thai economy and labor force.[1] In 2017, the value of all Thai rice traded was 174.5 billion baht, about 12.9% of all farm production.[2] Of the 40% of Thais who work in agriculture, 16 million of them are rice farmers by one estimate.[3][4] Soybeans Thailand produces only of soybeans a year, meeting only two percent of a total demand nearing three million tonnes. Thailand imports about two million tonnes annually to meet a growing demand from the livestock and aquaculture sectors both in Thailand and neighbouring countries. Poultry farms and
