| Abstract | Availability of cis-1,4-polyisoprene from Hevea brasiliensis has become important for many kinds of products, as it isused in automobiles, gloves, and adhesives. Increasing the yield of latex from rubber trees would contribute to income in tropicalcountries. The latex yield depends on various factors, including plant hormones and aging. This work focused on studying theeffects of these factors on dry rubber content and on proteome profiles. The results suggest that dry rubber content slightlydecreased upon hormonal treatment, and increased with maturation. Both factors affected the protein concentration. Comparativeproteomic analysis indicated that ethylene stimulation altered abundances of 1,553 soluble proteins and 1,001 rubber-boundproteins. Plant maturation affected abundances of 2,961 soluble proteins and 839 rubber-bound proteins. These results provideuseful information about the protein-level mechanisms of rubber biosynthesis, affecting rubber yield in response to hormonetreatment and aging. |
