“…The CYCD3 gene is activated by CTK to promote cell division. Arabidopsis shows marked dwarfing when CYCD3 is inhibited [ 47 ]. In this study, we found that CYCD3 (cluster-12007.20005), which is involved in BR signal transduction, was significantly downregulated and that the BR content was significantly decreased in the dwarf vs. tall groups of S. davidii , which indicates that S. davidii CYCD3 may be involved in the regulation of plant height and play a negative role in BR signal transduction, affecting the division of plant cells.…”

Sophora davidii is an important plant resource in the karst region of Southwest China, but S. davidii plant-height mutants are rarely reported. Therefore, we performed phenotypic, anatomic structural, transcriptomic and metabolomic analyses to study the mechanisms responsible for S. davidii plant-height mutants. Phenotypic and anatomical observations showed that compared to the wild type, the dwarf mutant displayed a significant decrease in plant height, while the tall mutant displayed a significant increase in plant height. The dwarf mutant cells were smaller and more densely arranged, while those of the wild type and the tall mutant were larger and loosely arranged. Transcriptomic analysis revealed that differentially expressed genes (DEGs) involved in cell wall biosynthesis, expansion, phytohormone biosynthesis, signal transduction pathways, flavonoid biosynthesis and phenylpropanoid biosynthesis were significantly enriched in the S. davidii plant-height mutants. Metabolomic analysis revealed 57 significantly differential metabolites screened from both the dwarf and tall mutants. A total of 8 significantly different flavonoid compounds were annotated to LIPID MAPS, and three metabolites (chlorogenic acid, kaempferol and scopoletin) were involved in phenylpropanoid biosynthesis and flavonoid biosynthesis. These results shed light on the molecular mechanisms of plant height in S. davidii mutants and provide insight for further molecular breeding programs.

Background: Cassava is one of the three major potato crops in the world, and also the sixth-largest food crop in the world. Improving yield is still one of the main goals of cassava breeding. Plant height has a significant impact on the yield and quality of crops. However, the mechanism of cassava plant height development is still unclear. Results: In this study, we performed phenotypic, anatomic structural, and transcriptomic analyses to study the mechanisms responsible for Cassava plant-height development. Phenotypic and anatomical observations showed that compared to the high-stem cassava cultivar, the dwarf-stem cassava cultivar displayed a significant decrease in plant height, while the internode tissue xylem area significantly increased. Physiological analysis showed that the lignin content of dwarf cassava was significantly higher than that of high cassava. Transcriptome analysis showed that genes involved in cell wall synthesis and expansion, plant hormone signal transduction, phenylpropanoid biosynthesis, and flavonoid biosynthesis were significantly differentially expressed in the internode tissues of two cassava cultivars. Conclusion: These results indicate that the internode tissue cell division, secondary wall lignification, and hormones and their related gene expressions play an important role in cassava plant height development. It provides new insights into the mechanism of plant height morphogenesis in cassava. In addition, these candidate genes that regulate plant height development can serve as valuable genetic resources for future crop dwarfing breeding.

Background Cassava is one of three major potato crops and the sixth most important food crop globally. Improving yield remains a primary aim in cassava breeding. Notably, plant height significantly impacts the yield and quality of crops; however, the mechanisms underlying cassava plant height development are yet to be elucidated. Results In this study, we investigated the mechanisms responsible for cassava plant height development using phenotypic, anatomical, and transcriptomic analyses. Phenotypic and anatomical analysis revealed that compared to the high-stem cassava cultivar, the dwarf-stem cassava cultivar exhibited a significant reduction in plant height and a notable increase in internode tissue xylem area. Meanwhile, physiological analysis demonstrated that the lignin content of dwarf cassava was significantly higher than that of high cassava. Notably, transcriptome analysis of internode tissues identified several differentially expressed genes involved in cell wall synthesis and expansion, plant hormone signal transduction, phenylpropanoid biosynthesis, and flavonoid biosynthesis between the two cassava cultivars. Conclusions Our findings suggest that internode tissue cell division, secondary wall lignification, and hormone-related gene expression play important roles in cassava plant height development. Ultimately, this study provides new insights into the mechanisms of plant height morphogenesis in cassava and identifies candidate regulatory genes associated with plant height that can serve as valuable genetic resources for future crop dwarfing breeding.
