摘要： In recent years, the global wheat yield has faced significant challenges due to the impact of climate change and population growth. One crucial agronomic factor affecting wheat yield is plant height, primarily determined by stem length. However, our understanding of wheat stem development is limited compared to other plant organs. To unravel the genetic regulation of wheat stem development, we conducted an RNA-seq analysis on 27 samples from different internodes at three developmental stages. In total, we obtained 63,056 genes from this spatiotemporal transcriptome data, which could be clustered into four groups: elongation group (EG), maintenance group (MG), and two transition groups (ETG and MTG). Gene ontology (GO) enrichment analysis revealed that genes highly expressed in EG samples were mainly associated with cell expansion and cell wall regulation, while MG samples were enriched in photosystem and carbohydrates metabolism. Transcription factor MYB61 and NAC29 in wheat were closely related to stem elongation and probably involved in cellulose metabolism. The construction of protein interaction networks also revealed candidate key genes such as TOR, UGPI and CESA7 in stem development regulatory network. These potential wheat plant height and stem strength regulating genes could provide important genetic resources for improving wheat lodging resistance and yield, which could be applied to cultivate wheat varieties with higher and stable yields.
