“…Lower accumulation of TCA cycle intermediates at growth light under combined cold and drought may also indicate a higher level of photorespiration and overreduction of NAD + /NADH ratio which reduces glycolysis and energy production. Additionally, the fact is that transaconitic acid, a geometric isomer of cis-aconitic acid, is generally more abundant in grasses and the exogenous application of this compound damaged photosynthesis in soybean (Bortolo et al 2018). The activity of aconitate isomerase did not regulate trans-aconitic acid content but its presence was found to be necessary for the accumulation of trans-aconitic acid in wheat seedlings (Thompson et al 1997).…”

“…Aconitic acid is another metabolite that was significantly upregulated by more than 2-fold in C3H/APX-KD compared to WT ( Supplement Table 7 ). This metabolite has been previously demonstrated to strongly inhibit the soybean ( Glycine max ) plant’s growth and its photosynthetic ability while enhancing the cellular H 2 O 2 content ( Bortolo et al., 2018 ). Metabolomics also detected a substantial decrease of an ascorbate conjugate metabolite which could be related to ascorbate recycling ( Supplement Table 7 ).…”

A bifunctional peroxidase enzyme, 4-coumarate 3-hydroxylase (C3H/APX), provides a parallel route to the shikimate shunt pathway for the conversion of 4-coumarate to caffeate in the early steps of lignin biosynthesis. Knockdown of C3H/APX (C3H/APX-KD) expression has been shown to reduce the lignin content in Brachypodium distachyon. However, like many other lignin-modified plants, C3H/APX-KDs show unpredictable pleiotropic phenotypes, including stunted growth, delayed senescence, and reduced seed yield. A system-wide level understanding of altered biological processes in lignin-modified plants can help pinpoint the lignin-modification associated growth defects to benefit future studies aiming to negate the yield penalty. Here, a multi-omic approach was used to characterize molecular changes resulting from C3H/APX-KD associated lignin modification and negative growth phenotype in Brachypodium distachyon. Our findings demonstrate that C3H/APX knockdown in Brachypodium stems substantially alters the abundance of enzymes implicated in the phenylpropanoid biosynthetic pathway and disrupt cellular redox homeostasis. Moreover, it elicits plant defense responses associated with intracellular kinases and phytohormone-based signaling to facilitate growth-defense trade-offs. A deeper understanding along with potential targets to mitigate the pleiotropic phenotypes identified in this study could aid to increase the economic feasibility of lignocellulosic biofuel production.

“…In this study, the allelopathic effects of root aqueous extracts from different ages of persistent roots on the cultivation of sugarcane seedlings were studied. The results showed that the allelochemicals released from the persistent roots of sugarcane may play three roles ( Bortolo et al., 2018 ; Li et al., 2021 ; Zhou et al., 2021 ). First, allelochemicals can affect the accumulation of osmoregulatory molecules, including REL and Pro, SP, and SS.…”

Sugarcane ratoon performance declines with increasing age due to the intergenerational accumulation and release of allelochemicals by old sugarcane roots. We aimed to clarify the effects of these allelochemicals on sugarcane seedling growth under continuous sugarcane ratoon cropping. We investigated the allelopathic effects of treatment with root aqueous extracts from sugarcane ratoons of different ages on the osmoregulatory substance content, antioxidant enzyme activity, membrane lipid peroxidation product content, photosynthetic physiological characteristics, and root exudate enzymatic characteristics of sugarcane seedlings. The root aqueous extracts exerted allelopathic effects on sugarcane seedlings. The relative electrolyte leakage, proline content, soluble protein content, soluble sugar content, malondialdehyde content, and catalase activity of the leaves were more sensitive than those of the roots. Conversely, the superoxide dismutase and peroxidase activities of the roots (positive response) were more sensitive than those of the leaves (negative response). The total chlorophyll content and net photosynthetic rate of the leaves exhibited relatively sensitive negative responses. Urease activity negatively responded but sucrase activity positively responded. We concluded that the root aqueous extracts of sugarcane ratoons may exert their allelopathic effects by affecting the level of osmoregulatory substances and causing peroxidative damage to the cell membranes of sugarcane seedlings and altering the activities of various enzymes in the rhizosphere.
