Rubber Tree(Hevea brasiliensis)Pathogenesis-related Proteins:Stress Resistance,Laticifer Plugging,Allergenicity,and Transgenic Breeding
摘要
Abstract
Pathogenesis-related(PR)proteins are crucial functional proteins in plants responding to stress,exhibiting multiple biological roles in rubber trees(Hevea brasiliensis).This article systematically reviewed recent advances in PR protein research in rubber trees,with emphasis on the functional characteristics in stress resistance mechanisms,laticifer plugging,and allergenicity,while highlighting the critical relationship between PR proteins and laticifer plugging.PR proteins participate in defense responses against stresses through complex molecular networks,potentially influencing latex yield via laticifer plugging processes.Some PR proteins exhibit strong allergenic properties.Although transgenic studies of PR proteins have achieved preliminary progress,further optimization of expression regulation strategies is required to balance stress resistance,yield,and allergenicity.Future research should prioritize elucidating the mechanis-tic roles of PR proteins,especially investigating how the expression levels of pathogenesis-related proteins(particularly chitinases and β-1,3-glucanases)correlate with rubber productivity.Concurrently,functional exploration of understudied PR protein categories like PR-14 warrants attention.Developing precise molecular breeding technologies based on these findings will provide both theoretical foundations and technical support for rubber tree variety improvement.关键词
