Basic helix-loop-helix (bHLH) proteins are transcription factors (TFs) that have been shown to regulate anthocyanin biosynthesis in many plant species. However, the bHLH gene family walnut ( Juglans regia L.) has not yet reported. In this study, 102 genes were identified genome and classified into 15 subfamilies according sequence similarity phylogenetic relationships. The structure, conserved domains, chromosome location of analyzed by bioinformatic methods. Gene duplication analyses revealed 42 JrbHLHs involved expansion family. We also characterized cis -regulatory elements these performed Ontology enrichment analysis functions, examined protein-protein interactions.

Hickory (Carya cathayensis) is a critical tree species of the genus Carya from Juglandaceae family that contains nutrient-rich nuts. Due to large-scale soil degradation, pests and diseases hickory are becoming more serious. Thaumatin-like proteins (TLPs) vital involved in complex defense process plant pathogens. In this study, 40 CcTLP genes were identified genome-widely phylogenetically grouped into three subfamilies. The sequence CcTLPs had conservative pattern, such as eight stable disulfide bonds, REDDD, G-X-[GF]-X-C-X-T-[GA]-D-C-X(1,2)-G-X-(2,3)-C structure. total, 57 cis-elements related stress-responsive, light-responsive, phytohormone-responsive, plant-responsive discovered. Under salicylate (SA), methyl jasmonate (MeJA), ethephon (ETH) treatments, expressions CcTLP28, CcTLP29, CcTLP30, CcTLP31, CcTLP32, CcTLP33, CcTLP37, CcTLP38, CcTLP39 different patterns. This an indication most TLP upregulated by SA downregulated MeJA. Notably, seven significantly under Botryosphaeria dothidea inoculation, especially with over 20-fold change. Nine shown subcellular localization analysis be located at plasma membrane cytoplasm. knowledge disease-resistant function promoted these results.

Intercropping with legume forages is recognized as an effective strategy for enhancing nitrogen levels in agroforestry, while mowing may influence fixation capacity and yield. This study investigated the rooting, fixation, nutritive value, yield of alfalfa (Medicago sativa L.) under intercropping varying frequencies (CK, 2, 3) from 2021 to 2023, using walnut (Juglans regia experimental subjects. The results indicated that suppressed root growth, whereas increased frequency stimulated development topsoil (0–20 cm). Specifically, average length density, surface area, volume twice- thrice-mowed treatments by 18.26, 17.45, 4.15%, respectively, comparison control. δ15N values intercropped were significantly lower than those monocropped (p < 0.05), mowing-thrice treatment increasing 38.61% compared but did not affect total content leaves or all resulted land equivalent ratios (LERs) greater 1.
