Summary: An endo-beta-1,3(4)-glucanase AnENG16A from Aspergillus nidulans exhibits distinctive catalytic features, producing 3-O-beta cellobiosyl-D-glucose and 3-O-beta gentiobiosyl-D-glucose with high antioxidant activity. The linkage type at the non-reducing end of beta-glucotrioses may enhance antioxidant activity compared to beta-1,3-linkage.

Summary: Perennial para- and endo-dormancy are seasonally separate phenomena. Para-dormancy is the suppression of axillary buds (AXBs) by a growing shoot, while endo-dormancy is the short-day elicited arrest of terminal and AXBs. ABA and GA play important roles in both phenomena. Blocking ABA biosynthesis reduced ABA levels, upregulated GA3ox-biosynthetic genes, and initiated branching, while blocking GA(4) biosynthesis promoted callose deposition and endo-dormancy. The results provide new insights into the roles of ABA and GA in dormancy cycling.

Summary: In eudicots, the role of callose in water uptake and seed metabolic events during germination is unclear. Suppressing GhGLU19 in cotton seeds improves germination by accumulating callose and modulating metabolism, providing a potential way to enhance germination in cotton production and other eudicot crops.

Summary: Rice sheath blight is a serious disease that affects rice production, but the mechanisms of defense are poorly understood. This study found that the expression levels of beta-glucanase family genes are responsive to infection and positively regulate rice resistance to sheath blight. OsBGL2 was also found to co-localize with AtPDCB1 and limit the permeability of plasmodesmata. The identification and functional elucidation of these genes help fill the gap in understanding the mechanism of plasmodesmata permeability in rice sheath blight resistance.

Summary: Fruit softening is an irreversible process that can cause losses and waste during postharvest transportation and storage. In this study, two cell wall-related genes in tomato were knocked out using genome editing, and it was found that simultaneous knockout of these genes enhanced fruit firmness and reduced cell wall disassembly.

Summary: This study analyzed the effects of chitosan on Fusarium infection in garlic. It was found that chitosan with low and medium molecular weight could inhibit the growth of Fusarium and prevent disease symptoms when applied as pre-treatment. The treatment also affected the activity of chitinase and beta-1,3-glucanase enzymes. In addition, chitosan treatment increased the transcription levels of related genes in garlic already infected with Fusarium.

Summary: Grafting is commonly used to enhance stress tolerance and fruit yield in horticultural crops. Ribonucleoprotein complexes consisting of mRNAs and proteins play crucial roles in communication between scions and stocks in grafted plants. This study identified a beta-1,3-glucanase (PbPDBG) that facilitates ankyrin-mediated callose degradation at plasmodesmata, promoting long-distance transport of ribonucleoprotein complexes. These findings underscore the importance of PbPDBG in ankyrin-mediated callose degradation.

Summary: In this study, a maize mutant named mlgh1 was identified with increased MLG content due to a mutation in the GRMZM2G137535 gene, which encodes a GH17 licheninase capable of degrading MLG. Overexpression of this gene resulted in a significant reduction in MLG content and increased saccharification yields. Moreover, cycling of MLG content during day/night cycles was disrupted in the mlgh1 mutant, suggesting a regulatory role of MLG degradation in gene expression.

Summary: In this study, a strain called Paenibacillus sp. GKG was isolated and found to produce hydrolysis zones. Proteomic analysis revealed the enzymes secreted by this strain. PsLam81A, an endo-beta-1,3-glucanase containing GH81 catalytic and CBM56 carbohydrate-binding modules, was identified and characterized. It was found that the CBM56 module enhanced the hydrolytic activity of specific substrates.

Summary: The mechanism of endo-type action on laminarin by GH55 endo-beta-1,3-glucanase MnLam55A was investigated, revealing its preference for cleaving the nonreducing terminal beta 1-3-linkage of the laminar-ioligosaccharide moiety. The crystal structure of MnLam55A showed similarities to exo-beta-1,3-glucosidases, but possessed an extended substrate-binding cleft.

Summary: Stipe elongation growth is driven by lateral extension of stipe cells, requiring loosening of the cell wall to accommodate protoplast enlargement. Chitinases are key in stipe wall extension, while 3-glucanases play a role in wall remodeling. Fungal expansin-like proteins may enhance chitin hydrolysis and aid in stipe wall extension growth.

Summary: The cell wall of mature pollen grain is a specialized structure with outer sporopollenin-based exine for protection and inner cellulose-based intine for germination. The complex process of wall development involves the deposition of multiple cell wall polymers in a controlled sequence. The development of tomato pollen wall has been described with a timeline of key events, including exine deposition, tapetum degeneration, and intine formation during pollen maturation.

Summary: The study found that the application of CuNPs is more beneficial for the biological and biochemical activities of Brassica napus rhizospheric soil compared to the application of AgNPs. The abundance of all tested microbial groups showed a positive correlation with CuNPs but a negative correlation with AgNPs in each application version. Additionally, the impact of different NP concentrations on soil pH value and biochemical parameters varied between CuNPs and AgNPs.

Summary: In this systemic review, the importance of non-forest woody vegetation (NFWV) for pollinators in agricultural landscapes is discussed. Flowering trees and shrubs in the temperate climate zone provide nectar sugar, pollen, nesting niches, and host plants for wild pollinators. Creating woodland strips/groups is a cost-effective strategy to improve pollinator habitats and ensure food resources throughout the year.
