Peran Trehalose Metabolisme Sepanjang Masa Kehidupan Tanaman

Abstract

Abstract
Trehalose/T6P has important role at entire plant stage of life starting from embryonic
stage, vegetative growth, generative growth and senescence. The roles include cell
devision, cell shape, plant architectecture, and plant responses to biotic and abiotic stress.
Syncrunizing between energy demand and energy availability is the main mode of the
roles through reprogramming of gene expression responsible for anabolism and/or
catabolism processes depending on given situation including biotic and abiotic stress.
Moreover, proteins of trehalose metabolism are suggested to affect enzyme activity of
target proteins. SnRK1 and bZIP11 involve in all those modes. Understanding crusial
roles of trehalose metabolism in plant therefore is necessary in order to get benefit from
this pathway for agricultural issue.
Abstrak
Trehalose/T6P berperan penting bagi tahapan kehidupan tanaman dari tahap embryo,
pertumbuahn vegetatif, pertumbuhan generatif, hingga sanesensi. Peran molekul tersebut
berpengaruh pada pembelahan sel, bentuk sel, arsitektur tanaman dan respon tumbuhan
terhadap stres biotik dan abiotik. Pengintegrasian antara kebutuhan dan ketersediaan
energi merupakan modus utama dalam peran tersebut melalui pemrograman ekspresi gen
yang bertanggung jawab terhadap proses anabolisme dan atau katabolisme sesuai dengan
situasi tertentu termasuk dalam kondisi stres biotic dan abiotik. Selain itu, protein-protein
dalam lintasan metabolisme trehalose ini juga diduga mempengaruhi aktivitas enzimenzim
target. Peran krusial metabolisme trehalose, manusia dapat memanfaatkan lintasan
ini untuk kepentingan pertanian.
