About

Dr. Jeongim Kim is an associate professor in the Horticultural Sciences Department at the University of Florida and a member of the Plant Molecular and Cellular Biology (PMCB) graduate program. She earned her PhD at Purdue University, where she studied auxin biosynthesis and plant abiotic stress physiology. During her post-doctoral training at Purdue, Dr. Kim focused on phenylpropanoid biosynthesis and participated in several projects aimed at increasing biofuel production. Her research interests center on understanding the molecular mechanisms underlying metabolic networks that integrate plant stress responses and growth.

• Aldoximes are precursors of auxins in Arabidopsis and maize

  New Phytologist · 2021 · 43 citations

  Senior authorCorresponding

  Two natural auxins, phenylacetic acid (PAA) and indole-3-acetic acid (IAA), play crucial roles in plant growth and development. One route of IAA biosynthesis uses the glucosinolate intermediate indole-3-acetaldoxime (IAOx) as a precursor, which is thought to occur only in glucosinolate-producing plants in Brassicales. A recent study showed that overproducing phenylacetaldoxime (PAOx) in Arabidopsis increases PAA production. However, it remains unknown whether this increased PAA resulted from hyd…

• Occurrence, Function, and Biosynthesis of the Natural Auxin Phenylacetic Acid (PAA) in Plants

  Plants · 2023-01-06 · 30 citations

  reviewOpen accessSenior authorCorresponding

  Auxins are a class of plant hormones playing crucial roles in a plant's growth, development, and stress responses. Phenylacetic acid (PAA) is a phenylalanine-derived natural auxin found widely in plants. Although the auxin activity of PAA in plants was identified several decades ago, PAA homeostasis and its function remain poorly understood, whereas indole-3-acetic acid (IAA), the most potent auxin, has been used for most auxin studies. Recent studies have revealed unique features of PAA distinc…

• Postharvest storage temperature strategies affect anthocyanin levels, total phenolic content, antioxidant activity, chemical attributes of juice, and physical qualities of blood orange fruit

  Food Chemistry Advances · 2024-05-08 · 29 citations

  articleOpen access

  The potential of storing ‘Budd Blood’ blood orange fruit at different temperatures (6, 8, 10, and 12°C) for 60 days after harvest was investigated to enhance anthocyanin, total phenolic content, antioxidant activity, and to understand temperature effects on other physicochemical attributes. Fruit weight and firmness losses increased during storage, with the lowest losses occurring at 6°C. Titratable acidity (TA) decreased, and the lowest values were recorded at 10 and 12°C. Total soluble solids…

• Profiling phenolic compounds in juice and peel of fourteen pomegranate (Punica granatum L.) varieties grown in Florida, USA

  Food Chemistry Advances · 2023-03-09 · 25 citations

  articleOpen access

  • A variation in phenolic compounds was found in juice and peel between 14 varieties. • Pomegranate peel contains the highest levels of gallic and ellagic acids. • Punicalagin a and b presented the highest phenolic content in pomegranate juice. Pomegranate ( Punica granatum L.) fruit contain several health-promoting compounds, but the profiles of these compounds and their variations in nutraceutical value are still lacking. Thus, the profile of phenolic compounds in juice and peel of fourteen po…

• Aldoxime Metabolism Is Linked to Phenylpropanoid Production in Camelina sativa

  Frontiers in Plant Science · 2020 · 25 citations

  Senior authorCorresponding

  involved in PAL degradation is up-regulated in the transgenic lines. Our results suggest a link between aldoxime metabolism and phenylpropanoid production in Camelina and that the molecular mechanism behind the crosstalk is conserved in Arabidopsis and Camelina.
