Hemileia vastatrix (#)
„Coffee rust is characterized by yellow-orange powdery lesions on the abaxial surface of leaves where it attacks through stomata; it rarely occurs on stems or fruit. All Coffea genotypes are susceptible to some degree, though cultivars such as Timor and Icatu exhibit a high resistance (Ferreira and Boley, 1991). Additional Rubiaceae can also be infected (Coutinho et al. 1995). Impaired photosynthesis, premature defoliation, and reduced floral initiation constitute most of the damage (Brown et al. 1995). This reduced photosynthetic capacity and the heavy carbohydrate sink created by fruits limit the amount the growth of woody tissue that gives rise to the next season's crop. Therefore, the following season's crop is reduced. In fact, losses due to coffee leaf rust can reach 70%, although 15-20% is more typical (Ferreira and Boley, 1991; Brown et al.“

„Researchers say they have genetically engineered coffee plants that have 70 percent less caffeine than usual in their leaves. The crucial question for brewing coffee - whether beans from those plants will have less caffeine - won't be known for three to four years when the plants mature, said study author Shinjiro Ogita.“

„In Latin America a popular drink is la yerba mate, or el mate, a tea brewed from the dried leaves of a native holly tree. In Argentina los gauchos, the cowboys of the high plains, reputedly drink mate throughout the day to maintain their strength. However you don't have to travel to the Andes to find it - the refreshing drink is available in most cafés and street corner bars.“

„The plant has shiny green leaves and small white flowers. Like coffee plants, the plants can grow to 30 feet in the wild, but they tea trees are pruned to around 3 feet for cultivation. Actually, the tea tree's leaves and the coffee plant's leaves look somewhat similar, only the tea leaves are smaller.“
