Mutualistic association can improve a plant's health and productivity. G-type lectin receptor-like kinase (PtLecRLK1) is a susceptibility factor in that permits root colonization by a beneficial fungus, . Engineering PtLecRLK1 also permits root colonization in non-host plants similar to . The intracellular signaling reprogramed by PtLecRLK1 upon recognition of to allow for the development and maintenance of symbiosis is yet to be determined. In this study, phosphoproteomics was utilized to identify phosphorylation-based relevant signaling pathways associated with recognition of in transgenic switchgrass roots. Our finding shows that in transgenic plants modifies the chitin-triggered plant defense and MAPK signaling along with a significant adjustment in phytohormone signaling, ROS balance, endocytosis, cytoskeleton movement, and proteasomal degradation in order to facilitate the establishment and maintenance of colonization. Moreover, protein-protein interaction data implicate a cGMP-dependent protein kinase as a potential substrate of .

Introduction: The binding of the spike (S) protein of SARS-CoV-2 to angiotensin-converting enzyme 2 (ACE2) is a critical stage in the process of infection. While previous studies indicated that the S protein and ACE2 are extensively glycosylated, the functions of glycans in their interactions remain uncertain.
Objectives: This study aimed to investigate the glycan receptors of SARS-CoV-2 and evaluate the inhibitory effects of galactosylated glycoproteins derived from bovine milk on the attachment of SARS-CoV-2 pseudovirus.

Article Synopsis
- Solanum lycopersicum, a key crop, has its genome sequenced, revealing important information about lectin receptor-like kinases (LecRLKs), particularly L-type and G-type families.
- The study identified 161 lectin genes in the tomato genome, with gene duplication analysis showing that tandem and segmental duplications significantly contribute to the expansion of G-type LecRLKs.
- Differential expression analysis during abiotic stresses (like drought and heat) highlighted specific LecRLK genes, suggesting their roles in stress response and the potential for improving crop resilience through genetic strategies.

This study examines the invasion and immune evasion mechanisms of a highly virulent strain through transcriptomic profiling of tilapia gills following acute immersion. We identified 8192 differentially expressed genes (DEGs) at 2 h, 6 h, and 12 h post-infection.

Cucumber () fruit spines are a classic material for researching the development of multicellular trichomes. Some key genes that influence trichome development have been confirmed to be associated with cuticle biosynthesis and secondary metabolism. However, the biological mechanisms underlying trichome development, cuticle biosynthesis, and secondary metabolism in cucumber remain poorly understood.
