“…ANNEXIN genes encode calcium-dependent phospholipid-binding proteins and represent a multigene family in both plants and animals ( Mortimer et al., 2008 ; Divya et al., 2010 ). They can function as Ca 2+ -binding and regulating channels or participate in diverse cellular processes including responses to environmental stresses and signaling during plant growth and development ( Jami et al., 2012 ; Yadav et al., 2018 ; He et al., 2019 ; Saad et al., 2020 ).…”

Annexin 1 (ANN1) is the most abundant member of the evolutionary conserved multigene protein superfamily of annexins in plants. Generally, annexins participate in diverse cellular processes, such as cell growth, differentiation, vesicle trafficking, and stress responses. The expression of annexins is developmentally regulated, and it is sensitive to the external environment. ANN1 is expressed in almost all Arabidopsis tissues, while the most abundant is in the root, root hairs, and in the hypocotyl epidermal cells. Annexins were also occasionally proposed to associate with cytoskeleton and vesicles, but they were never developmentally localized at the subcellular level in diverse plant tissues and organs. Using advanced light-sheet fluorescence microscopy (LSFM), we followed the developmental and subcellular localization of GFP-tagged ANN1 in post-embryonic Arabidopsis organs. By contrast to conventional microscopy, LSFM allowed long-term imaging of ANN1-GFP in Arabidopsis plants at near-environmental conditions without affecting plant viability. We studied developmental regulation of ANN1-GFP expression and localization in growing Arabidopsis roots: strong accumulation was found in the root cap and epidermal cells (preferentially in elongating trichoblasts), but it was depleted in dividing cells localized in deeper layers of the root meristem. During root hair development, ANN1-GFP accumulated at the tips of emerging and growing root hairs, which was accompanied by decreased abundance in the trichoblasts. In aerial plant parts, ANN1-GFP was localized mainly in the cortical cytoplasm of trichomes and epidermal cells of hypocotyls, cotyledons, true leaves, and their petioles. At the subcellular level, ANN1-GFP was enriched at the plasma membrane (PM) and vesicles of non-dividing cells and in mitotic and cytokinetic microtubular arrays of dividing cells. Additionally, an independent immunolocalization method confirmed ANN1-GFP association with mitotic and cytokinetic microtubules (PPBs and phragmoplasts) in dividing cells of the lateral root cap. Lattice LSFM revealed subcellular accumulation of ANN1-GFP around the nuclear envelope of elongating trichoblasts. Massive relocation and accumulation of ANN1-GFP at the PM and in Hechtian strands and reticulum in plasmolyzed cells suggest a possible osmoprotective role of ANN1-GFP during plasmolysis/deplasmolysis cycle. This study shows complex developmental and subcellular localization patterns of ANN1 in living Arabidopsis plants.

“…Os CEBiP is the major long-chain CO receptor in rice, whereas Os CERK1 does not appear to bind COs directly [ 19 , 24 , 25 ]. However, the Os CERK1 from rice may play a bifunctional role, and in complex with the co-receptor Os LYK2, stimulates the recognition of CO4-5 and activation of specific symbiotic reactions [ 15 , 26 , 27 ]. Similarly, a bifunctional role of the homolog of the CERK1 receptor in the banana Musa acuminata ( Ma LYK1) during pathogenic and symbiotic interactions has been identified [ 28 ].…”

This study focused on the interactions of pea (Pisum sativum L.) plants with phytopathogenic and beneficial fungi. Here, we examined whether the lysin-motif (LysM) receptor-like kinase PsLYK9 is directly involved in the perception of long- and short-chain chitooligosaccharides (COs) released after hydrolysis of the cell walls of phytopathogenic fungi and identified in arbuscular mycorrhizal (AM) fungal exudates. The identification and analysis of pea mutants impaired in the lyk9 gene confirmed the involvement of PsLYK9 in symbiosis development with AM fungi. Additionally, PsLYK9 regulated the immune response and resistance to phytopathogenic fungi, suggesting its bifunctional role. The existence of co-receptors may provide explanations for the potential dual role of PsLYK9 in the regulation of interactions with pathogenic and AM fungi. Co-immunoprecipitation assay revealed that PsLYK9 and two proposed co-receptors, PsLYR4 and PsLYR3, can form complexes. Analysis of binding capacity showed that PsLYK9 and PsLYR4, synthesized as extracellular domains in insect cells, were able to bind the deacetylated (DA) oligomers CO5-DA–CO8-DA. Our results suggest that the receptor complex consisting of PsLYK9 and PsLYR4 can trigger a signal pathway that stimulates the immune response in peas. However, PsLYR3 seems not to be involved in the perception of CO4-5, as a possible co-receptor of PsLYK9.

Background Genome-wide association study (GWAS) has become an accepted and powerful method for understanding the associations between phenotypes and genotypes. In agricultural production, uniform and rapid germination is an important prerequisite in crop production. Here, a rice (Oryza sativa L.) GWAS with 33,934 SNPs (MAF > 0.05) for eight germination traits including germination percentage (GP), shoot (SL) and root length (RL), root (RFW) and shoot fresh weight (SFW), root (RDW) and shoot (SDW) dry weight, and number of days to germinate (NDG) was performed to define genomic regions influencing seed germination. Results Loci (43) with 70 significant germination-associated markers were detected across all rice chromosomes. Some of novel candidate associated genes were: LOC_Os01g26210 (OsWAK6) co-located with qGR-1 that is seed vigor QTL, LOC_Os07g23944 (GH31) with an α-glucosidases /starch lyase activity; id7000519 marker that corresponds to a gene cluster containing glutathione S-transferase and glucan endo-1,3-β-glucosidase co-located with qAG3 germination-related marker, LOC_Os06g47640 (calmodulin-related calcium sensor protein 29) involved in the inhibition of ABA during seed germination, and id4006430 marker that corresponds to a gene cluster containing three GH17 hydrolytic enzyme that are co-located with qHD4 and qGI1 markers. Conclusion The germination process is an initial and important step in the production of agricultural products, especially for rice, which is a crop plant that is grown in flooded lands. Here, the genetic diversity of rice genotypes was put under scrutiny for germination. Our GWAS results identified several likely candidate genes for germination traits that will greatly contribute to our understanding of the genetic complexity underlying the corresponding traits. The associated genes with the germination traits can be generally classified as hydrolytic enzymes and regulatory proteins that can directly or indirectly influence germination.
