“…Our research found that 3 ET response factors ( ERF92s ) interact with the 4 class II chitinases ( CHIs ) ( Figure 7 ). Previous research has shown that CHI participates in the catabolic process of cell wall macromolecules ( De Andrade Silva et al., 2020 ). Under boron deficiency, ERF92s were downregulated, while CHIs were upregulated in A. melanoxylon stem ( Supplementary Files 6 , 8 ).…”

Boron is an essential micronutrient for plant growth as it participates in cell wall integrity. The growth and development of Acacia melanoxylon stem can be adversely affected by a lack of boron. To explore the mechanism of boron deficiency in A. melanoxylon stem, the changes in morphological attributes, physiological, endogenous hormone levels, and the cell structure and component contents were examined. In addition, the molecular mechanism of shortened internodes resulting from boron deficiency was elucidated through transcriptome analysis. The results showed that boron deficiency resulted in decreased height, shortened internodes, and reduced root length and surface area, corresponding with decreased boron content in the roots, stems, and leaves of A. melanoxylon. In shortened internodes of stems, oxidative damage, and disordered hormone homeostasis were induced, the cell wall was thickened, hemicellulose and water-soluble pectin contents decreased, while the cellulose content increased under boron deficiency. Furthermore, plenty of genes associated with cell wall metabolism and structural components, including GAUTs, CESAs, IRXs, EXPs, TBLs, and XTHs were downregulated under boron deficiency. Alterations of gene expression in hormone signaling pathways comprising IAA, GA, CTK, ET, ABA, and JA were observed under boron deficiency. TFs, homologous to HD1s, NAC10, NAC73, MYB46s, MYB58, and ERF92s were found to interact with genes related to cell wall metabolism, and the structural components were identified. We established a regulatory mechanism network of boron deficiency-induced shortened internodes in A. melanoxylon based on the above results. This research provides a theoretical basis for understanding the response mechanism of woody plants to boron deficiency.

“…Studies describe witches’ broom as a serious problem for world cocoa production, as the disease can cause various negative effects on plantations, as found in countries in which the disease has occurred (de Andrade Silva et al, 2020; Hedger et al, 1987; Meinhardt et al, 2008). The literature reports that of all the continents in the world, the disease is restricted to the Americas and the Caribbean, constituting a bottleneck for cocoa production in these areas (Fiorin et al, 2018; Marelli et al, 2019).…”

The cocoa tree (Theobroma cacao) is native to the Americas, specifically South America, in the region of the Amazon Rainforest (Ploetz, 2007). Among the indigenous peoples inhabiting tropical America, the plant has such importance that it became known as the food of the gods (de Souza et al., 2018). The cocoa tree is from the Malvaceae family, which is composed of the former families Sterculiaceae, Bombacaeae, Malvaceae sensu lato, and Tiliaceae (Ploetz, 2007).The fruits of the tree, called cocoa, appear along the trunk of the plant. The beans, considered the most commercially profitable part of the plant, are inside the pods. Currently, the international trade in cocoa beans has made cocoa farming an important activity for several countries (Fiorin et al., 2018).Cocoa bean production is the basis of the billion-dollar industry of cocoa transformation (Moretti-Almeida et al., 2019). Various products are obtained from the beans, chocolate being the most important and well known (Pimenta Neto et al., 2018;de Souza et al., 2018). Cocoa is produced in countries in Africa, Asia, South America, and Central America among others; however, Africa is the largest producer in the world (Pimenta Neto et al., 2018). Among the cocoa-producing countries, Ivory Coast (Côte d'Ivoire), Ghana, and Indonesia stand out, as they are responsible for more than half of the world production of cocoa beans (Campos-Vega et al., 2018).

“…The use of interactomics and homology between genes and proteins provides a basis for the functional association of genes [14]. Such an approach using PPI networks based on model organisms has already been successfully used to understand T. cacao-pathogen interactions or M. perniciosa development, among others [15,16]. This approach allows for a better understanding of the molecular and physiological mechanisms and processes in the plant.…”

Cupuassu (Theobroma grandiflorum [Willd. ex Sprengel] Schumann) seeds constitute the raw material for oil extraction and fabrication of cupulate (product similar to chocolate). However, fungal diseases such as witches’ broom caused by Moniliophthora perniciosa have interfered with the large-scale development of cupuassu plantations. Cupuassu genetic breeding programmes focus on a variety of biotechnological tools or approaches to select genes related to quality or resistance mechanisms. In this study, we used expression and interactomics analyses of preselected genes involved in fruit quality and/or resistance to better understand the molecular and physiological mechanisms associated with these plant processes. It was found that i) resistant and susceptible cupuassu genotypes showed different pulp characteristics as well as gene expression patterns; ii) monosaccharide and carbohydrate transport pathways were enhanced during fruit maturation; iii) sugar accumulation participated in signal transduction associated with fruit development and stress response in maturing fruits; and iv) maturing pulp and seeds showed increased phospholipid metabolism and translocation, as well as immune system activation. The TgSTP1, TgWRKY33, TgCZF1, and TgUBA1 genes in cupuassu and the orthologues of DIN10, CNI1, and TET8 identified by the interactomics approach may be good candidates for marker-assisted selection in breeding programmes focusing on both fruit quality and resistance/tolerance to biotic/abiotic stress.
