Summary: Pectin, including RG-I and HG, plays a central role in seed mucilage formation. This study identified the function of pectin HG in seed coat mucilage formation. The results showed that HG is required for the synthesis and expansion of seed mucilage, and it interacts with cellulose and other pectin domains to regulate its formation, expansion, and release.

Summary: This study reveals that the phosphorylation of Arabidopsis cellulose synthase 1 (AtCESA1) plays a role in regulating pectin synthesis and methylesterification in seed coat mucilage. Through the construction of mutant and transgenic lines, it was found that the phosphorylation state of AtCESA1 at the T166 site can affect the cell wall organization, as well as the levels and methylesterification of pectin and cellulose in seeds. Therefore, the phosphorylation of AtCESA1 is important for the regulation of seed development.

Summary: This study comprehensively characterized the roles of IQD9 and KLCR1 in cell wall polysaccharide biosynthesis in the seed coat epidermis. The results demonstrate that IQD9 and KLCR1 are crucial for the maintenance of seed mucilage architecture. Additionally, members of the IQD, KLCR and TRM families were found to have overlapping roles in cell wall biosynthesis.

Summary: Hull-less pumpkins, characterized by the absence of a normal lignified seed coat, are a model for studying seed coat formation. Through analysis, a mutation in the CpNST1 gene was found to be responsible for the lack of secondary cell wall biosynthesis in hull-less seed coats. The study provides mechanistic insight into seed coat secondary cell wall biosynthesis and identifies a target gene for breeders.

Summary: Parkinson's disease is characterized by the degeneration of dopaminergic neurons and the accumulation of Lewy bodies. Previous studies have examined the molecular mechanism linking nitroxidation, aS aggregation, and PD, but the impact of nitroxidation on the physiological function of aS was unclear. Our research found that nitroxidation of Y39 lengthened the disordered stretch between two consecutive alpha-helices and prevented aS from functioning as a catalyst for the clustering and fusion of synaptic vesicles.

Summary: DF1 is a key regulator of mucilage RG-I biosynthesis and interacts with GL2 to transcriptionally regulate the expression of MUM4 and GATL5. The expression of DF1 is directly regulated by TTG2 and DF1 also directly represses the expression of TTG2.

Summary: In this study, a thin-film nanocomposite (TFN) membrane with promising performance for solvent-resistant nanofiltration applications was prepared. The membrane consisted of a blend sheet of high-density polyethylene-polystyrene (PS), a basil seed mucilage-Fe(III) cross-linked interlayer, and a polyamide active layer with incorporated nanoparticles. The TFN membrane showed extraordinary dye rejection and solvent resistance compared to a similar TFC membrane.

Summary: The type III secreted transcription activator-like effector Tal2g of the rice bacterial leaf streak (BLS) pathogen Xanthomonas oryzae pv. oryzicola promotes lesion development and bacterial exudation through stomata by upregulating a putative sulfate transporter gene in rice, OsSULTR3;6. The transport mechanics, subcellular localization, potential substrates, and phenotyping of OsSULTR3;6 knockout lines generated by genome editing are being characterized to understand its role in BLS disease development.

Summary: Mortality in fisheries bycatch poses a threat to sea snakes globally. Population structure and reproductive strategies of Hydrophis schistosus and H. curtus in bycatch were studied, showing differences in mortality rates, breeding cycles, and reproductive efforts between the two species. Gravid female H. schistosus were observed carrying young from November to May, giving birth in April, while no gravid H. curtus were encountered during sampling. (C) 2021 Elsevier B.V.

Summary: This study examines the non-linear relationship between productivity growth and market power in Central European manufacturing firms from 2009 to 2017. The results show a concave relationship between both variables, and that firms in competitive industries respond more sensitively to market power. The study contributes to the literature by using both firm-level Lerner indexes and country-industry-level concentration measures to ensure robustness.

Summary: More than 200 years after von Humboldt's pioneering work on the treeline, our understanding of the cold distribution limit of upright plant growth is still incomplete. Contrary to popular belief, this study shows that the lignification of cell walls in 'woody' herbs can vary greatly, and small plants above the treeline may contain less lignin. The findings suggest that extremely cold temperatures can affect a plant's ability to lignify their secondary cell walls.

Summary: BPA is used as a precursor in the synthesis of plastics, but its presence in the environment is causing toxicity as an endocrine-disrupting chemical. Through computational studies, we have found that P450 2C9 converts BPA into hydroxycumyl alcohol as the main product. The low spin state and the properties of the substrate play important roles in determining the reaction pathway and product distribution.

Summary: Plants adapt to freezing stress through cold acclimation and deacclimation, which are regulated by changes in cell wall structure and monosaccharide composition. The balance between freezing tolerance and growth is crucial for plant development in changing environments. Arabinogalactan proteins and pectic galactan play important roles in freezing tolerance and growth, while arabinan and xyloglucan stabilize at cold acclimation levels during deacclimation.

Summary: A chemoattractant of plant-parasitic root-knot nematodes has been isolated from the Super-growing Root culture system and found to be enriched in carbohydrates, particularly arabinose and galactose. This attractant is essential for the attraction of Meloidogyne incognita but not other nematode species.

Summary: Bones play a crucial role in supporting the body, providing structure, enabling motion, and serving various other functions. The relationship between bone structure and mechanical properties is not fully understood. Through atomistic molecular dynamics simulations, we investigate the structure and mechanical properties of bone molecular models composed of collagen, hydroxyapatite, and water. Our findings reveal that the mineral and water contents of bones contribute significantly to stress levels, highlighting the importance of studying bone mechanical properties at the nanoscale.

Summary: Ion mobility mass spectrometry (IM-MS) techniques are valuable for structural characterization of biomolecular systems. However, interpreting IM-MS data is often challenging due to conformational isomerism. To address this, we developed MassCCS, an open-source code that computes the collision cross-section (CCS) of molecules using atomic and molecular buffer gas particles. MassCCS is highly accurate and efficient, especially for large macromolecular assemblies. Extensive tests showed its reliability, scalability, and performance. The code is freely available at https://github.com/cces-cepid/massccs.

Summary: Type II arabinogalactans (AGs) are diverse plant polysaccharides found in cell walls and plasma membranes as carbohydrate moieties in arabinogalactan-proteins (AGPs). The main structure of type II AG is a 1,3-beta-D-galactan main chain with 1,6-beta-D-galactan side chains decorated with sugars like alpha-L-arabinose and beta-D-glucuronic acid. Determining the structures of these complex AGs is challenging, but their modification offers scientific and commercial opportunities. This review outlines the chemical structures of type II and type II related AGs, compares structural analysis techniques, and highlights structural modifications for enhanced functionality.

Summary: This study explores the importance of cell shape for cotyledon morphogenesis in Arabidopsis. The results show that changes in cell shape lead to abnormal cotyledon shapes, and suggest that reduced cell wall cellulose content and altered cortical microtubule organization may contribute to cell deformation. Mathematical modeling and computer simulations further support these experimental observations, demonstrating that elongation of pavement cells results in irregular cotyledon shapes.
