We used the ORGANISMS web resource (Pafilis et al., 2013) to programmatically identify taxa comentioned with C. arabica (NCBI Taxonomy ID: 13443) in PubMed abstracts. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors. The filter function was used to rank plant species or genera according to their co‐occurrence at the site of first discovery of H. vastatrix (Lake Kenya region) (Ferreira & Boley, 1991; Waller, 1982) and/or the site of first reported outbreak of CLR (Sri Lanka [Ceylon]) (Berkeley & Broome, 1869). Similarly, R. prinoides is the alternate host of Puccinia coronate (causal pathogen of crown rust in cultivated and wild oat) (Nazareno et al., 2017). Infections can spread quickly, and leaf rust infestations have the ability to wipe out entire coffee crops. These rust pathogens have been reported to infect eight diverse host plants from six different families in greenhouse inoculation experiments (Kaitera, Hiltunen, & Hantula, 2017). Since the ORGANISMS web resources uses fully automated pattern matching to identify taxa from the NCBI Taxonomy in PubMed abstracts, the mentions contained in ORGANISMS may contain both false‐positive matches (the taxon is falsely recognized in the abstract) and false‐negative matches (the taxon is falsely overlooked in the abstract). While coffee rust was known to be indigenous to coffee-growing regions of Africa, it was unheard of on the South American continent.

Rubus is of high interest as it is the only commonly found genus in both the category one ranking of the HAHR and with the ATM method. To begin with, an initial plant species pool was compiled, consisting of 377 different species or genera collated from different sources relating to flora mapping at one of the approximate sites of origin of native (undomesticated) coffee(south‐western highlands of Ethiopia). It lacks the urediniospore stage of the life cycle. Entering through the Carquinez Straits at San Francisco, the winds split northwards into the Sacramento Valley and southwards into the San Joaquin Valley. The rust pathogen can be easily transported long distances by wind. Furthermore, these plant species are known hosts of Hemileia holstii (MyCoPortal, 2018), Kuehneola uredinis (Van Reenen, 1995), and Puccinia coronata (Nazareno et al., 2017), respectively. The cedar-apple rust fungus is an example of a microcyclic, heteroecious rust, because while it does require both the apple and the red-cedar tree to complete its life cycle, it produces only four types of spores. et Br., was first detected in Coffea arabica in January 1970, in the southern region of Bahia state. Previous reports of susceptibility to Hemileia spp. Filed Under: Conventional, News, Plant Diseases. in order to survive.. the flax rust fungus Melampsora ... for the alternate hosts for two economically important species such as the soybean rust fungus P. pachyrhizi and the coffee rust H. vastatrix (Slaminko et al., 2008; Talhinhas et al., 2017). Dry urediniospores can survive up to 6 weeks on detached plant tissue, but will only germinate again in the presence of rain or heavy dew (Arneson, 2000). Despite the need for the alternate host, like many ‘macrocyclic’ rust species (those requiring two separate hosts), T. discolor is capable of continued growth on stone fruit and nut trees. One of the major diseases threatening coffee production is coffee leaf rust (CLR), caused by the biotrophic rust fungus, Hemileia vastatrix Berk. Due to these aspects of spore transmission and the fact that urediniospores have a limited ability to survive on nonliving coffee leaves, we assumed that this first CLR outbreak was the result of the longer‐living teliospores being transported to Sri Lanka on dry plant material. Abstract Coffee leaf rust (CLR), caused by the fungal pathogen Hemileia vastatrix, has plagued coffee production worldwide for over 150 years. Some macrocyclic rust fungi complete their life cycle on a single host and are called autoecious, whereas others require two different or alternate hosts and are called heteroecious. The 2012 Coffee leaf rust epidemic In 2012 there was a major increase in coffee rust across ten Latin American and Caribbean countries. The HAHR method produced a low‐ranking short list (Table 1), a medium‐ranking list (Table 2), and a high‐ranking list (Table 3) of plant species. These taxa included plants, animals, fungi, and bacteria. or other rust pathogens were prioritized in the final ranking. First identified in the 1860s in both East Africa and Sri Lanka, the pathogen Hemileia Vastatrix — which causes leaf rust or “la roya” in Spanish — has since made its way all over the coffee-growing world. plantations world‐wide (McCook, 2006), and the white pine blister rust (Cronartium ribicola) which has been epidemic in the native ranges of North American white pines (Pinus sp.) Thus, it is a problem that is nothing short of costly. They generally do not kill the host plant but can severely reduce growth and yield. ORGANISMS recognizes terms from the NCBI Taxonomy via ATM and is updated weekly.

The causal organism of stone fruit and nut rust disease is called Tranzschelia discolor. This occurs through repeated cycling of the uredial state, often referred to as the ‘repeating stage.’ That is, the uredial fruiting bodies can give rise to urediospores that repeatedly infect stone fruit and nut trees. A manual cross‐referencing approach was applied to the list of species generated by the ATM method by using the “find” function in MS Excel for all of the plant species listed in the HAHR method (Tables 1-3). Coffee rust was first reported in the East African coffee trees around Lake Victoria in 1861 and likely originated in the area. Today, the disease is present in virtually all arabica and conilon (Coffea canephora) coffee-growing areas of Brazil, and continues to threaten coffee production with losses that range from 30 to 50 %. The rust of faba beans is macrocyclic, or contains 5 spores during its life cycle. Mitochondrial genomes have been identified and reported in a couple of rust genomic studies, not only for high-quality draft genomes but also for rust fungi with no reference genomes or with low quality assembly, e.g., the coffee rust fungus (H. vastatrix) and the soybean rust fungi (Ph. Transcontinental air dispersion of H. vastatrix urediniospores has been reported, but this spore type is more frequently dispersed locally by rain‐splash due to a tendency to adhere strongly to each other, to leaves, and to smooth surfaces (Brown & Hovmøller, 2002; Nutman, Roberts, & Bock, 1960). In the mid 1800’s coffee leaf rust obliterated the coffee industry in Sri Lanka (Ceylon) and changed its agriculture completely (it is now the fourth largest producer of tea).
