Spermidine synthase is an enzyme that catalyzes the transfer of the propylamine group from
S-adenosylmethionine to putrescine in the biosynthesis of spermidine, and which plays a …

A cDNA for a putative 42kD spermidine synthase (OsSPDS2) was cloned from rice. The
deduced OsSPDS2 sequence showed highest similarity with Arabidopsis AtSPDS3 …

In the present study, we isolated a spermidine synthase gene from Antheraea pernyi
(ApSpds) using expressed sequence tag method. The obtained cDNA sequence of 1483 bp …

Two cDNAs from young pea fruits coding for functional spermidine synthases (EC 2.5. 1.16)
were isolated. The corresponding genes were named psSPDSYN1 and psSPDSYN2. Both …

Spermidine possesses multiple healthy functions, and soybeans contain the most abundant
spermidine. In this study, spermidine contents of soybeans from different varieties and …

Polyamines, including putrescine, spermidine, and spermine, play essential roles in a wide
variety of prokaryotic and eukaryotic organisms. Rice (Oryza sativa) contains four putative …

Spermidine synthase (SPDS) is a key enzyme in the polyamine anabolic pathway. SPDS
genes help regulate plant response to environmental stresses, but their roles in pepper …

Of the polyamines (PAs), plants contain at least two kinds of tetraamines, spermine (Spm)
and thermospermine (T-Spm). They seem to have different functions in plants because the …

The Arabidopsis genome contains four genes that encode proteins similar to both
spermidine synthase and spermine synthase of other organisms. Our previous study …

Polyamines are ubiquitous positively charged metabolites that play an important role in wide
fundamental cellular processes; because of their importance, the homeostasis of these …
