Research Progress on Biology of Rubber Production in Rubber Tree

doi:10.3969/j.issn.1000-2561.2020.10.003

Abstract

Abstract:

Natural rubber (cis-1, 4-polyisoprene) is an important industrial raw material, commercially harvested mainly from rubber tree (Hevea brasiliensis). Important progresses have been made in the past decade on Hevea biology of rubber production, focusing on rubber biosynthesis and latex production. The present review summarized the major progress in four research areas with relation to rubber production, i.e. Hevea genome sequencing, rubber transferase, transgenic research, and transcriptomics & proteomics. Moreover, the problems were discussed and a few of research emphasis in the next 5 to 10 years were proposed. When describing the studies of rubber transferase, the recent progress in several other rubber-producing plants were included.

Key words: Hevea brasiliensis (para rubber tree), biology of rubber production, genome sequencing, rubber transferase
