Jasmonic Acid Methyl Ester
Jasmonate (JA) and its derivatives are lipid-based plant hormones that regulate a wide range of processes in plants, ranging from growth and photosynthesis to reproductive development. In particular, JAs are critical for plant defense against herbivory and plant responses to poor environmental conditions and other kinds of abiotic and biotic challenges. Some JAs can also be released as volatile organic compounds (VOCs) to permit communication between plants in anticipation of mutual dangers. History The isolation of methyl jasmonate (MeJa) from jasmine oil derived from '' Jasminum grandiflorum'' led to the discovery of the molecular structure of jasmonates and their name in 1962 while jasmonic acid itself was isolated from '' Lasiodiplodia theobromae'' by Alderidge et al in 1971. Biosynthesis Biosynthesis is reviewed by Acosta and Farmer 2010, Wasternack and Hause 2013, and Wasternack and Song 2017. Jasmonates (JA) are oxylipins, i.e. derivatives of oxygenated fatty acid. ...

Jasminum Grandiflorum
''Jasminum grandiflorum'', also known variously as the Spanish jasmine, Royal jasmine, Catalan jasmine, among others, is a species of jasmine native to South Asia, the Arabian peninsula, East and Northeast Africa and the Yunnan and Sichuan regions of China. The species is widely cultivated and is reportedly naturalized in Guinea, the Maldive Islands, Mauritius, Réunion, Java, the Cook Islands, Chiapas, Central America, and the Caribbean.It is closely related to, and sometimes treated as merely a form of, ''Jasminum officinale''.Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . The plant is known as "saman pichcha" or "pichcha" in Sri Lanka. Description It is a scrambling deciduous shrub growing to 2–4 m tall. The leaves are opposite, 5–12 cm long, pinnate with 5–11 leaflets. The flowers are produced in open cymes, the individual flowers are white having corolla with a basal tube 13–25 mm long and five lobes 13–22 mm long.Flora of C ...
