Functional and genomic characterization of a wound- and methyl jasmonate-inducible chalcone isomerase in Eremochloa ophiuroides [Munro] Hack.

Eremochloa ophiuroides, a perennial warm-season lawn grass, has a characteristic phenotype of red pigmentation in tissues during maturation. The putative gene families associated with the red coloration were previously identified in E. ophiuroides.

Rice terpene synthase 20 (OsTPS20) plays an important role in producing terpene volatiles in response to abiotic stresses.

This study examined the volatile terpenes produced by rice seedlings in response to oxidative stress induced by various abiotic factors. Solid-phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) analyses revealed that when exposed to UV-B radiation, rice seedlings emitted a bouquet of monoterpene mixtures in a time-dependent manner. The mixtures comprised limonene, sabinene, myrcene, α-terpinene, β-ocimene, γ-terpinene, and α-terpinolene.
