“…The core members of the JA-signaling pathway, including SCF COI1 (SKP1 + Cdc53/cullin + Rbx1 + F-box) E3 ubiquitin ligase, JAZ repressor proteins, and MYC2 TF, have been defined as the COI1-JAZs-MYC2 module . In our previous study, four key gene families including COI1, allene oxide synthase (AOS), allene oxide cyclase (AOC), and MYC of the JA signaling pathway were genome-wide characterized in sugarcane and indicated that ShCOI1 - 4/5/6 , ShAOS1 , and ScAOC1 genes enhanced sugarcane tolerance to salt, cold, drought, ABA, or S. scitamineum stress, but ShMYC4 negatively regulated the defense response to pathogen stress .…”

Sugarcane response to Sporisorium scitamineum is determined by multiple major genes and numerous microeffector genes. Here, time-ordered gene coexpression networks were applied to explore the interaction between sugarcane and S. scitamineum. Totally, 2459 differentially expressed genes were identified and divided into 10 levels, and several stress-related subnetworks were established. Interestingly, the Ca 2+ signaling pathway was activated to establish the response to sugarcane smut disease. Accordingly, two CAX genes (ScCAX2 and ScCAX3) were cloned and characterized from sugarcane. They were significantly upregulated under ABA stress but inhibited by MeJA treatment. Furthermore, overexpression of ScCAX2 and ScCAX3 enhanced the susceptibility of transgenic plants to the pathogen infection, suggesting its negative role in disease resistance. A regulatory model for ScCAX genes in disease response was thus depicted. This work helps to clarify the transcriptional regulation of sugarcane response to S. scitamineum stress and the function of the CAX gene in disease response.

“…In addition, lots of stressrelated modified proteins involved in ROS signaling, Ca 2+ signaling, PAL metabolic, glyoxalase system, and hormone metabolism were also identified (Figure 6c and Table S12) and could be induced under cold, drought or S. scitamineum stress (Figure 7 and Table S13). Our group has discovered that an Lascorbate peroxidase 6 gene (APX6), 87 a glyoxalase I gene (SoGloI), 88 a gretchen hagen 3 (ScGH3−1), 89 an allene oxide synthase gene (ShAOS1), 90 two calcineurin B-like protein genes (ScCBL2−1 and ScCBL3−1), 91 two catalase genes (ScCAT1 and ScCAT2), 39,92,93 three thaumatin-like proteins genes (ScTLP1, ScTLP2, and ScTLP3), 94,95 three β-1,3glucanase genes (ScGluA1, ScGluD1, and ScGluD2), 96,97 four chitinase genes (ScChi, ScChiI1, ScChiIV1, and ScChiVII1) 98,99 and the ten CBL-interacting protein kinase genes (ScCIPKs) 100 were involved in sugarcane tolerance to SA, MeJA, ABA, hydrogen peroxide (H…”

In plants, lysine acetylation (Kac), 2-hydroxyisobutyrylation (Khib), and lysine lactylation (Kla), the three new types of post-translational modification (PTM), play very important roles in growth, development, and resistance to adverse environmental stresses. Herein, we report the first global acetylome, 2-hydroxyisobutyrylome, and lactylome in sugarcane. A total of 8573 Kac, 4637 Khib, and 215 Kla sites across 3903, 1507, and 139 modified proteins were identified. Besides, homology analyses revealed the Kac, Khib, and Kla sites on histones were conserved between sugarcane and rice or poplar. Functional annotations demonstrated that the Kac, Khib, and Kla proteins were mainly involved in energy metabolism. In addition, a number of modified transcription factors and stress-related proteins, which were constitutively expressed in different tissues of sugarcane and induced by drought, cold or Sporisorium scitamineum stress, were identified. Finally, a proposed working mode on how PTM functions in sugarcane was depicted. We thus concluded that PTM should play a role in sugarcane growth, development, and response to biotic and abiotic stresses, but the mechanisms require further investigation. The present study provided the all-new comprehensive profile of proteins Kac, Khib, and Kla and a new perspective to understand the molecular mechanisms of protein PTMs in sugarcane.

“…Examples of dual-specific AOS genes include a barley enzyme capable of producing α-ketols from both 9-and 13-hydroperoxides of fatty acids [23]. The 9/13-AOSs were identified in other monocot species, including maize [6,19], rice [33], and sugarcane [34], based on their phylogenetic relationship and ability to produce both 9-and 13-ketols. Some dicot species also contain a similar mixed-function AOS, including tulips [35], tomatoes [26], and potatoes [28].…”

Ketols Emerge as Potent Oxylipin Signals Regulating Diverse Physiological Processes in Plants

Plants produce an array of oxylipins implicated in defense responses against various stresses, with about 600 oxylipins identified in plants to date. Most known oxylipins are the products of lipoxygenase (LOX)-mediated oxygenation of polyunsaturated fatty acids. One of the most well-characterized oxylipins produced by plants is the hormone jasmonic acid (JA); however, the function of the vast majority of oxylipins remains a mystery. One of the lesser-studied groups of oxylipins is comprised of ketols produced by the sequential action of LOX, allene oxide synthase (AOS), followed by non-enzymatic hydrolysis. For decades, ketols were mostly considered mere by-products of JA biosynthesis. Recent accumulating evidence suggests that ketols exhibit hormone-like signaling activities in the regulation of diverse physiological processes, including flowering, germination, plant–symbiont interactions, and defense against biotic and abiotic stresses. To complement multiple reviews on jasmonate and overall oxylipin biology, this review focuses specifically on advancing our understanding of ketol biosynthesis, occurrence, and proposed functions in diverse physiological processes.
