A unique highly reducing polyketide synthase (HR-PKS) with a reductase domain was identified in a betaenone biosynthetic gene cluster. Successful heterologous expression and characterization of the HR-PKS and trans-acting enoyl reductase (ER) provide insights into the core structure formation with a decalin scaffold and allow reconstitution of the betaenone biosynthetic machinery.

Cyanobacteria are widespread, photosynthetic, gram-negative bacteria that generate numerous bioactive secondary metabolites complex biosynthetic enzymatic machinery. The model cyanobacterium sp. strain PCC 7002, hereafter referred to as PCC 7002, contains a type I polyketide synthase (PKS), termed olefin synthase (OlsWT), that synthesizes 1-nonadecene and 1,14-nonadecadiene: α-olefins that are important for growth at low temperatures.

Recent genome mining work revealed that unexplored habitats exhibit great potential for discovering new nonribosomal peptides (NRPs) and ribosomally synthesized and post-translationally modified peptides (RiPPs). Lanthipeptides are a group of RiPPs exhibiting a variety of biological functions. They are characterized by the presence of the thioether-containing bis-amino acids lanthionine and/or methyllanthionine.

The JAZ protein family, serving as a key negative regulator in the jasmonic acid signaling pathway, interacts with transcription factors to play an essential role in plant growth, development, and stress responses. However, minimal research has focused on the role of JAZ transcription factors in regulating the growth, development, and stress responses of maize. In this study, we cloned the JAZ gene ZmJAZ13 from maize (Zea mays L.

Jujube (Ziziphus ujuba Mill.) holds great importance as a fruit tree in China, with strong tolerance to drought and saline stress, but its growth is limited by vulnerability to cold stress. Consequently, the role of MAPK cascades in mediating jujube cold stress response remains unclear, with the specific function of ZjMAPKK4 in this context yet to be fully elucidated.
