Flavin Monooxygenase-Generated N-Hydroxypipecolic Acid Is a Critical Element of Plant Systemic Immunity
Michael Hartmann,Tatyana Zeier,Friederike Bernsdorff,Vanessa Reichel-Deland,Denis Kim,Michele Hohmann,Nicola Scholten,Stefan Schuck,Andrea Bräutigam,Torsten Hölzel,Christian Ganter,Jürgen Zeier +11 more
TL;DR: A pathogen-inducible L-Lys catabolic pathway in plants that generates the N-hydroxylated amino acid NHP as a critical regulator of systemic acquired resistance to pathogen infection is identified.

Expression of the c-kit Proto-Oncogene and Its Ligand Stem Cell Factor (SCF) in Normal and Malignant Human Testicular Tissue
T. Strohmeyer,T. Strohmeyer,David Reese,David Reese,Michael Press,Michael Press,Rolf Ackermann,Rolf Ackermann,Michael Hartmann,Michael Hartmann,Dennis Slamon,Dennis Slamon +11 more
TL;DR: The detection of the c-kit receptor in normal human germ cells and its natural ligand SCF in Sertoli cells suggests the presence of a local trophic regulatory system that may be active in human spermatogenesis.

Biochemical Principles and Functional Aspects of Pipecolic Acid Biosynthesis in Plant Immunity
Michael Hartmann,Denis Kim,Friederike Bernsdorff,Ziba Ajami-Rashidi,Nicola Scholten,Stefan Schreiber,Tatyana Zeier,Stefan Schuck,Vanessa Reichel-Deland,Jürgen Zeier +9 more
TL;DR: Combined mass spectrometric and infrared spectroscopic analyses of in vitro assays and plant extracts indicate that the final product of the ALD1-catalyzed reaction is enaminic 2,3-dehydropipecolic acid (DP), whose formation involves consecutive transamination, cyclization, and isomerization steps.

N-hydroxypipecolic acid and salicylic acid: a metabolic duo for systemic acquired resistance.
Michael Hartmann,Jürgen Zeier +1 more
TL;DR: The biochemistry of NHP formation from l-Lys is outlined and novel progress on SA biosynthesis in Arabidopsis and other plant species is addressed to ensure elevated plant immunity.

l-lysine metabolism to N-hydroxypipecolic acid: an integral immune-activating pathway in plants.
Michael Hartmann,Juergen Zeier +1 more
TL;DR: A third l-lysine metabolic pathway having a major role in plant systemic acquired resistance (SAR) to pathogen infection that was recently discovered in Arabidopsis thaliana is covered, and it is shown that NHP is glycosylated inArabidopsis to form a hexose-conjugate, and open questions in Pip/NHP-related research are discussed.
