“…Proteasome (ko03051), phenylpropanoid biosynthesis (ko00940), cytochrome P450 (ko00199), the biosynthesis of various plant secondary metabolites (ko00999), and other pathways showed enrichment in the black module. The DEGs involved in cell wall biosynthesis, expansion, phytohormone biosynthesis, signal transduction pathways, flavonoid biosynthesis, and phenylpropanoid biosynthesis were significantly enriched in Salix matsudana plant-height mutants [51]. Phenylpropanoid biosynthesis is closely related to wood formation [52] and plant height [53].…”

The Gleditsia genus has various uses, including those for medicinal, edible, chemical, timber, and ornamental purposes, and the genus is widely distributed in China. However, there is still a lack of understanding about the phenotypic and growth differences seen among species within the Gleditsia genus. In this study, we compared and analyzed the various species of Gleditsia seedlings in terms of their genotypes, chromosome numbers, physiological growth, photosynthesis, hormone content, and gene expression. The results showed that the genome size of the Gleditsia genus ranges from 686.08 M to 1034.24 M and that all Gleditsia species are diploid. Among the species studied, G. fera can be divided into fast-growing genotype, exhibited several advantages in terms of leaf type and photosynthetic capacity, high levels of GA3, and fast stem growth, making it a species with the potential for promotion and application. G. delavayi exhibited high levels of auxin and cytokinin and strong photosynthetic capacity, with rapid growth in terms of plant height. G. microphylla had the lowest levels of IAA, IBA, and NAA in the apical, and showed slow growth in terms of plant height. Weighted correlation network analysis (WGCNA) identified the hub genes associated with traits. This study lays a material and theoretical foundation for the development of new resources for Gleditsia breeding and rootstock selection and provides a basis for the mechanism of rootstock–scion interaction.

“…An F 1 individuals of Salix matsudana Koidz was produced by cross-breeding the male parent "9901" and the female parent "Yanjiang" in 2014 (Liu et al, 2021c). The branches of 30 female F 1 progenies and 30 male F 1 progenies were clipped at 10 cm lengths and 1 cm thicknesses and hydroponically cultured in water under two conditions, with water only (i.e., the normal condition, marked as "CK") and with 0.5% NaCl solution (g/v) (i.e., the salinity stress condition, marked as "T").…”

Sexual dimorphism has commonly been found in many species. The phenotypes of Salix matsudana females and males are different under salinity stress. An F1 population was selected to compare the differences between males and females. As a result, males showed stronger roots and heavier dry weights than females. The unique molecular mechanisms of males and females under salinity stress were further analyzed based on the root transcriptome of males and females. Both males and females up-regulated systemic acquired resistance genes, such as ADH and oxygenase-related genes, to resist salt. Moreover, many other abiotic stress response genes were up-regulated in males to adjust to salinity stress, while females showed more down-regulation of nitrogen metabolism-related genes to decrease the harm from salinity stress. The research on salinity tolerance in Salix matsudana males and females would help to further understand sexual dimorphism under selection pressure and provide benefits to the ecological environment.

The study of the gravity response of roots and shoots is of great significance when exploring the polarity of plants and the development of the forest industry. In our study, normal and inverted cuts of Salix matsudana (Koidz) were cultured. The total RNAs of roots and shoots were extracted. Based on the comparative transcriptome, 412 and 668 genes were differentially expressed. The plasma membrane-, cell wall-, and extracellular region-related genes were up-regulated in the shoots, while the carbon metabolism and the nitrogen metabolism were up-regulated in the roots. Combining the alternative splicing genes, we found a potential gravity response network: in the shoots, LecRLKs were highly sensitive to gravity and further affected the alternative splicing of SNARE, as well as inducing an inhomogeneous distribution of auxin and a negative geotropism curve. In the roots, AP2/ERFs and STRKs were highly sensitive to gravity and regulated the expression level of STPKs and WAKs, finally resulting in a geotropism curve. Moreover, cell division was suppressed in both the roots and the shoots under inverted conditions with different mechanisms. Cell division inhibitors (KRPs) were up-regulated in the roots, while DNA helicase MCMs were down-regulated in the shoots. These results provide an important foundation for further studies of the molecular mechanisms and genetic regulation of plant responses to gravity and the plant polarity of forest trees.
