Differential expression of metabolites in genetic variants of the endangered plant Ziziphus celata.

Ziziphus celata (Florida jujube) is a spiny flowering shrub native to Florida, found only along the Lake Wales Ridge in Highlands and Polk Counties. It is officially listed as "endangered" at federal and state levels and very little is known about it. Efforts continue to characterize compounds in genomic variants of this species in order to make inforined decisions regarding habitat restoration. Gas chromatography - mass spectrometry (GC-MS) and ultra-performance liquid chromatography - tandem mass spectrometry (UPLC-MS/MS) with multiple reaction monitoring were used to obtain coinparative information on the metal)olites detected in two distinct genotypes (labeled 436 and 353) of the plant. These data were analyzed by relative signal, class, subclass, and KEGG pathway. Where possible, this information was connected to specific plant functions. This information will help to shed light on the varied strategies used by Ziziphus celata for communication, defense, stress response. growth regulation, and other survival processes.
