TL;DR: It is proposed that JA evolved as a plant hormone for stress adaptation, beginning with the emergence of vascular plants, and the four active enzymes have characteristics similar to those in seed plants.
Abstract: Jasmonic acid (JA) is involved in a variety of physiological responses in seed plants. However, the detection and role of JA in lycophytes, a group of seedless vascular plants, have remained elusive until recently. This study provides the first evidence of 12-oxo-phytodienoic acid (OPDA), JA and jasmonoyl-isoleucine (JA-Ile) in the model lycophyte Selaginella moellendorffii. Mechanical wounding stimulated the accumulation of OPDA, JA and JA-Ile. These data were corroborated by the detection of enzymatically active allene oxide synthase (AOS), allene oxide cyclase (AOC), 12-oxo-phytodienoic acid reductase 3 (OPR3) and JA-Ile synthase (JAR1) in S. moellendorffii. SmAOS2 is involved in the first committed step of JA biosynthesis. SmAOC1 is a crucial enzyme for generating the basic structure of jasmonates and is actively involved in the formation of OPDA. SmOPR5, a functionally active OPR3-like enzyme, is also vital for the reduction of (+)-cis-OPDA, the only isomer of the JA precursor. The conjugation of JA to Ile by SmJAR1 demonstrates that S. moellendorffii produces JA-Ile. Thus, the four active enzymes have characteristics similar to those in seed plants. Wounding and JA treatment induced the expression of SmAOC1 and SmOPR5. Furthermore, JA inhibited the growth of shoots in S. moellendorffii, which suggests that JA functions as a signaling molecule in S. moellendorffii. This study proposes that JA evolved as a plant hormone for stress adaptation, beginning with the emergence of vascular plants.

TL;DR: The results showed a wide distribution of culturable chitinolytic bacteria in the rhizospheres of various agronomic plants, which could potentially be utilized for the biological control of soil-borne phytopathogenic fungi.
Abstract: A total of 100 isolates of chitinolytic bacteria were obtained from the rhizospheres of various agronomic plants, and the 16S rRNA gene sequences of these isolates were determined. Phylogenetic analyses revealed that 81 isolates belonged to the classes Betaproteobacteria (39 isolates) and Gammaproteobacteria (42 isolates). Of the remaining 19 isolates, 16 belonged to the phylum Firmicutes. Clustering analysis identified 6 and 3 operational taxonomic units (OTUs) in Gammaproteobacteria and Betaproteobacteria, respectively, at the genus level. The majority of chitinolytic bacteria in Gammaproteobacteria belonged to the genera Serratia, Stenotrophomonas, and Lysobacter (14, 15, and 7 isolates, respectively) while those in Betaproteobacteria belonged to the genus Mitsuaria (37 isolates). The 16 isolates placed in Firmicutes belonged to 2 genera, Paenibacillus and Bacillus (8 isolates each). The isolates in the remaining OTUs belonged to the genera Erwinia, Aeromonas, Pseudomonas, Achromobacter, Flavobacterium, and Microbacterium, in less abundance. These results showed a wide distribution of culturable chitinolytic bacteria in the rhizospheres of various agronomic plants. Considering the potential antagonistic activity of chitinolytic enzymes against phytopathogenic fungi, which is exhibited by fungal cell wall degradation, the above-mentioned native chitinolytic bacteria in rhizospheres could potentially be utilized for the biological control of soil-borne phytopathogenic fungi.
