“…Transient overexpression of miR7125 or repression of its target, CCR, in apple fruit decreased lignin deposition under light-induced conditions [117]. In chickpea, overexpressing CamiR397 decreased the transcript levels of its targets, LAC4 and LAC17L and lignin accumulation in the root xylem and reduced xylem wall thickness [118]. A similar role of miR397 was observed during stone cell development in pear fruit [119].…”

Lignin is an important secondary metabolite that maintains the mechanical strength of horticultural plants and enhances their ability to respond to external environmental changes such as biotic and abiotic stresses. However, excessive accumulation of lignin can lead to lignification of horticultural products, reducing their taste quality and nutritional value. Therefore, the lignin content of horticultural products needs to be controlled at a reasonable level, and studying and regulating lignin metabolism is very meaningful work. This article focuses on the synthesis, accumulation, and regulation of lignin in horticultural crops in recent years, provides a systematic analysis of its molecular mechanism and application prospects, and sheds insights into the directions that need further research in the future. This article provides an important basis for the regulation of lignin accumulation and lignification in horticultural crops and proposes new ideas for improving the quality of horticultural crops.

“…We observed that the expression levels of 4CL (CA.PGAv.1.6.scaffold546.13) and CCoAOMT (CCoAOMTCA.PGAv.1.6.scaffold354.27) were up-regulated in KANG ( Figure 9 and Figure S2 ), which modulated the lignin content, implying they may influence the resistance of pepper to C. capsici . In the chickpea root, microRNA397 reportedly regulates the tolerance to drought and fungal infections by controlling lignin deposition [ 35 ]. Phytohormones play a critical role in plant responses to viral infections [ 36 ].…”

Pepper (Capsicum annuum L.) is a herbaceous plant species in the family Solanaceae. Capsicum anthracnose is caused by the genus Colletotrichum. spp., which decreases pepper production by about 50% each year due to anthracnose. In this study, we evaluated the resistance of red ripe fruits from 17 pepper varieties against anthracnose fungus Colletotrichum capsici. We assessed the size of the lesion diameter and conducted significance analysis to identify the resistant variety of B158 and susceptible variety of B161. We selected a resistant cultivar B158 and a susceptible cultivar B161 of pepper and used a transcription to investigate the molecular mechanisms underlying the plant’s resistance to C. capsici, of which little is known. The inoculated fruit from these two varieties were used for the comparative transcription analysis, which revealed the anthracnose-induced differential transcription in the resistant and susceptible pepper samples. In the environment of an anthrax infection, we found that there were more differentially expressed genes in resistant varieties compared to susceptible varieties. Moreover, the response to stimulus and stress ability was stronger in the KANG. The transcription analysis revealed the activation of plant hormone signaling pathways, phenylpropanoid synthesis, and metabolic processes in the defense response of peppers against anthracnose. In addition, ARR-B, AP2-EREBP, bHLH, WRKY, and NAC are associated with disease resistance to anthracnose. Notably, WRKY and NAC were found to have a potentially positive regulatory role in the defense response against anthracnose. These findings contribute to a more comprehensive understanding of the resistance mechanisms of red pepper fruit to anthracnose infection, providing valuable molecular insights for further research on the resistance mechanisms and genetic regulations during this developmental stage of pepper.

“…Likewise, the altered accumulation of lignin in the plant SCW leads to different responses to drought. For instance, the microRNA CamiR397 in chickpea (Cicer arietinum) can target the transcripts of lignin biosynthesis genes, reducing plant sensitivity to drought and pathogen infection by decreasing deposition of lignin (Sharma et al 2023). Overexpression of PtoMYB170 in transgenic poplar leads to stronger ligni cation and thicker SCW in xylem (Xu et al 2017).…”

Moso bamboo (Phyllostachys edulis) is a highly valuable woody bamboo species. A better understanding of its regulation of lignin deposition would significantly benefit its cultivation and breeding. Here, we identified PeMYB26, an transcription factor gene that is primarily expressed in the vascular system. PeMYB26 encodes an R2R3-MYB transcriptional activator that localizes to the nucleus. Heterologous expression of PeMYB26 under control of the cauliflower mosaic virus 35S promoter caused widening of xylem, thickening of vessel elements, and deposition of lignin in transgenic tobacco (Nicotiana tabacum) plants. Moreover, transcript abundances of the lignin biosynthesis genes PAL（PHENYLALANINE AMMONIA-LYASE）, CAD（CINNAMYL ALCOHOL DEHYDROGENASE）, COMT（CAFFEATE O-METHYLTRANSFERASE） and CCR （CINNAMOYL CoA REDUCTASE ）were markedly higher in N. tabacum lines overexpressing PeMYB26 than in control lines. In particular, the expression of PeCCR was highly promoted by PeMYB26. These results indicate that PeMYB26 plays a positive role in regulating lignin accumulation and xylem formation.
