“…Nodulin genes are found in high transcript levels in floral tissues (Szczyglowski and Amyot, 2003). Other enod40 genes have been cloned from non-legumes include tomato (Vleghels et al, 2003), maize (Compaan et al, 2003), rye grass ( Lolium ) and barley ( Hordeum ) (Knud, 2003). Enod40 levels are elevated during arbuscular mycorrhizal root colonization of tobacco ( Nicotiana bentana ) and alfalfa ( Medicago truncatula ) (Sinvany et al, 2002).…”

Proteomic Studies on the Effects of Lipo-Chitooligosaccharide and Thuricin 17 under Unstressed and Salt Stressed Conditions in Arabidopsis thaliana

Plants, being sessile organisms, are exposed to widely varying environmental conditions throughout their life cycle. Compatible plant-microbe interactions favor plant growth and development, and help plants deal with these environmental challenges. Microorganisms produce a diverse range of elicitor molecules to establish symbiotic relationships with the plants they associate with, in a given ecological niche. Lipo-chitooligosaccharide (LCO) and Thuricin 17 (Th17) are two such compounds shown to positively influence plant growth of both legumes and non-legumes. Arabidopsis thaliana responded positively to treatment with the bacterial signal compounds LCO and Th17 in the presence of salt stress (up to 250 mM NaCl). Shotgun proteomics of unstressed and 250 mM NaCl stressed A. thaliana rosettes (7 days post stress) in combination with the LCO and Th17 revealed many known, putative, hypothetical, and unknown proteins. Overall, carbon and energy metabolic pathways were affected under both unstressed and salt stressed conditions when treated with these signals. PEP carboxylase, Rubisco-oxygenase large subunit, pyruvate kinase, and proteins of photosystems I and II were some of the noteworthy proteins enhanced by the signals, along with other stress related proteins. These findings suggest that the proteome of A. thaliana rosettes is altered by the bacterial signals tested, and more so under salt stress, thereby imparting a positive effect on plant growth under high salt stress. The roles of the identified proteins are discussed here in relation to salt stress adaptation, which, when translated to field grown crops can be a crucial component and of significant importance in agriculture and global food production. The mass spectrometry proteomics data have been deposited to the ProteomeXchange with identifier PXD004742.

“…These findings indicate that ENOD40 was originally involved in another plant developmental pathway, and was then recruited into the symbiotic nodulation pathway. However, a maize knockout mutant of an ENOD40 homolog showed no phenotypic aberrations in plant growth or development (21).…”

In recent years, numerous biochemical and genetic studies have demonstrated that peptide signaling plays a greater than anticipated role in various aspects of plant growth and development. A substantial proportion of these peptides are secretory and act as local signals mediating cell-to-cell communication. Specific receptors for several peptides were identified as being membrane-localized receptor kinases, the largest family of receptor-like molecules in plants. These findings illustrate the importance of peptide signaling in the regulation of plant growth, functions that were previously ascribed to the combined action of small lipophilic compounds referred to as "traditional plant hormones." Here, we outline recent advances in the current understanding of biologically active peptides in plants, currently regarded as a new class of plant hormones.

“…Gene silencing of two Medicago truncatula ENOD40 genes, ENOD40‐1 and ENOD40‐2 , demonstrated that both genes are involved in nodule initiation and bacteroid development (Wan et al ., 2007). Orthologues of ENOD40 have also been found in other non‐legume plants, suggesting roles outside of symbiosis (Kouchi et al ., 1999; Compaan et al ., 2003; Vleghels et al ., 2003; Gulyyaev and Roussis, 2007). When soybean ENOD40 was expressed in wheat germ extracts, two peptides with sizes of 12‐ (peptide A) and 24 (peptide B) amino acid residues were formed (Röhrig et al ., 2002).…”

SummaryExtracellular plant peptides perform a large variety of functions, including signalling and defence. Intracellular peptides often have physiological functions or may merely be the products of general proteolysis. Plant peptides have been identified and, in part, functionally characterized through biochemical and genetic studies, which are lengthy and in some cases impractical. Peptidomics is a branch of proteomics that has been developed over the last 5 years, and has been used mainly to study neuropeptides in animals and the degradome of proteases. Peptidomics is a fast, efficient methodology that can detect minute and transient amounts of peptides and identify their post-translational modifications. This review describes known plant peptides and introduces the use of peptidomics for the detection of novel plant peptides.
