“…Cellulose accounts for approximately 20% of plant primary cell walls and approximately 50% of secondary cell walls by weight (Baez et al ., 2022 ). Almost all the genes related to cellulose synthesis were increased from Melioideae to Cedreloideae; the gene numbers of cellulose synthase A (CESA), glycosyltransferase STELLO1 (STL), cellulose synthase interactive protein (CSI) and sucrose synthetases (SUS) in T. sinensis genome were almost double of those in A. indica and M. azedarach (Figure S5 ).…”

Summary Meliaceae is a useful plant family owing to its high‐quality timber and its many limonoids that have pharmacological and biological activities. Although some genomes of Meliaceae species have been reported, many questions regarding their unique family features, namely wood quality and natural products, have not been answered. In this study, we provide the whole‐genome sequence of Melia azedarach comprising 237.16 Mb with a contig N50 of 8.07 Mb, and an improved genome sequence of Azadirachta indica comprising 223.66 Mb with a contig N50 of 8.91 Mb. Moreover, genome skimming data, transcriptomes and other published genomes were comprehensively analysed to determine the genes and proteins that produce superior wood and valuable limonoids. Phylogenetic analysis of chloroplast genomes, single‐copy gene families and single‐nucleotide polymorphisms revealed that Meliaceae should be classified into two subfamilies: Cedreloideae and Melioideae. Although the Meliaceae species did not undergo additional whole‐genome duplication events, the secondary wall biosynthetic genes of the woody Cedreloideae species, Toona sinensis, expanded significantly compared to those of A. indica and M. azedarach, especially in downstream transcription factors and cellulose/hemicellulose biosynthesis‐related genes. Moreover, expanded special oxidosqualene cyclase catalogues can help diversify Sapindales skeletons, and the clustered genes that regulate terpene chain elongation, cyclization and modification would support their roles in limonoid biosynthesis. The expanded clans of terpene synthase, O‐methyltransferase and cytochrome P450, which are mainly derived from tandem duplication, are responsible for the different limonoid classes among the species. These results are beneficial for further investigations of wood development and limonoid biosynthesis.

“…Hemicellulose helps maintain the integrity and stability of the cell wall, and can account for 25% of the secondary wall's content (Baez et al, 2022;Julian and Zabotina, 2022). Hemicellulose can be divided into three classes: xylan, glucomannan and galactoglucomannan.…”

“…Thus, plant growth and morphogenesis are mechanistically controlled by the properties of cell walls. Plants have evolved signaling mechanisms to monitor the changes in the cell wall structure, thereby triggering corresponsive responses to sustain cell wall integrity (CWI) [ 2 , 3 , 4 ]. Changes in cell wall architecture can occur under environmental stresses or some developmental processes [ 5 ].…”

Plant cell walls are essential structures for plant growth and development as well as plant adaptation to environmental stresses. Thus, plants have evolved signaling mechanisms to monitor the changes in the cell wall structure, triggering compensatory changes to sustain cell wall integrity (CWI). CWI signaling can be initiated in response to environmental and developmental signals. However, while environmental stress-associated CWI signaling has been extensively studied and reviewed, less attention has been paid to CWI signaling in relation to plant growth and development under normal conditions. Fleshy fruit development and ripening is a unique process in which dramatic alternations occur in cell wall architecture. Emerging evidence suggests that CWI signaling plays a pivotal role in fruit ripening. In this review, we summarize and discuss the CWI signaling in relation to fruit ripening, which will include cell wall fragment signaling, calcium signaling, and NO signaling, as well as Receptor-Like Protein Kinase (RLKs) signaling with an emphasis on the signaling of FERONIA and THESEUS, two members of RLKs that may act as potential CWI sensors in the modulation of hormonal signal origination and transduction in fruit development and ripening.

“…Firstly thought as a physical barrier that hinders the entry of the pathogen into the protoplast, the CW is also the first system that participates in the perception of the intruder upon pathogen apparition (Bacete et al, 2018; Vaahtera et al, 2019; Molina et al, 2021) and it is a metabolically-active cellular compartment in which different enzymes participate reinforcing and/or maintaining the structure (Delaunois et al, 2014; Farvardin et al, 2020). This defensive structure is composed of cellulose, hemicellulose (such as xyloglucan or xylans) and pectin (such as homogalacturonan -HG- and rhamnogalacturonan I and II –RGI and RGII-) polysaccharides, whose proportions can vary depending on the tissue and plant species and under the pressure of different biotic and abiotic stresses (Baez et al, 2022). The development of disease could be the result of the pathogen interfering with one or more of all these defensive responses.…”

The molecular mechanism that drives the resistance/susceptibility of common bean to Pseudomonas syringae pv. phaseolicola (Pph) has not been clarified yet. For this purpose, 15-day-old common bean plants, variety riñón, were infected with Pph to analyze the transcriptomic changes at 2 and 9 h. RNA-seq analysis showed an upregulation of defense-related genes at 2h, most of them being downregulated at 9h, suggesting that Pph would inhibit the transcriptomic reprogramming of the plant. This trend was also observed in the modulation of 101 cell wall (CW) related genes. However, the changes in CW composition at early stages of Pph infection were related to homogalacturonan (HG) methylation and the formation of HG egg boxes. A common bean pectin methylesterase inhibitor 3 (PvPMEI3) gene - closely related to AtPMEI3 - was detected. In addition, PMEI3 protein was located in the apoplast and had inhibitory activity. Therefore, PvPMEI3 seems to be a good candidate to play a key role in infection, because Arabidopsis pmei3 mutant showed susceptibility to Pph. All these changes could be an attempt to reinforce the CW structure and thus, hinder the attack of the bacterium. However, these transcriptional and CW-remodeling processes are not deep enough to block the action of the pathogen.
