Tea is the second most popular nonalcoholic beverage consumed in the world, made from the buds and young leaves of the tea plants (). Tea trees, perennial evergreen plants, contain abundant specialized metabolites and suffer from severe herbivore and pathogen attacks in nature. Thus, there has been considerable attention focusing on investigating the precise function of specialized metabolites in plant resistance against pests and diseases.

Article Synopsis
  • Tea plants face tough environments and rely on jasmonates to manage both biotic (like pests and diseases) and abiotic (like extreme weather) stresses.
  • Recent developments in understanding jasmonic acid biosynthesis and its signaling pathways are highlighted, emphasizing their role in the plants' stress responses.
  • Future research aims to enhance knowledge of the JA pathway, with an emphasis on improving genetic transformation techniques to identify new regulatory components.

Article Synopsis
  • * When tea plants were attacked by a pest called Ectropis grisescens, they produced more quercetin glucosides, which are a special form of quercetin.
  • * A specific protein called UGT89AC1 is important for making these protective substances, and plants with less of it had more trouble keeping the pests from growing.

Herbivore-induced plant volatiles prime neighbouring plants to respond more strongly to subsequent attacks. However, the key volatiles that trigger this state and their priming mechanisms remain largely unknown. The tea geometrid Ectropis obliqua is one of the most devastating leaf-feeding pests of tea plants.

Gay, bisexual, and other men who have sex with men (MSM) continue to be the population most affected by human immunodeficiency virus (HIV) in the United States. In 2014, 81% of diagnoses of HIV infection were among adult and adolescent males, and among these, 83% of infections were attributable to male-to-male sexual contact (1). Since 2006, CDC has recommended HIV testing at least annually for sexually active MSM to foster early detection of HIV infection and prevent HIV transmission (2,3).
