Abstract Background Wheat is one of the most widely planted crops worldwide. The heading date is important for wheat environmental adaptability, as it not only controls flowering time but also determines the yield component in terms of grain number per spike. Results In this research, homozygous genotypes with early and late heading dates derived from backcrossed progeny were selected to conduct RNA-Seq analysis at the double ridge stage (W2.0) and androgynous primordium differentiation stage (W3.5) of the leaf and apical meristem, respectively. In total, 18,352 differentially expressed genes (DEGs) were identified, many of which are strongly associated with wheat heading date genes. Gene Ontology (GO) enrichment analysis revealed that carbohydrate metabolism, trehalose metabolic process, photosynthesis, and light reaction are closely related to the flowering time regulation pathway. Based on MapMan metabolic analysis, the DEGs are mainly involved in the light reaction, hormone signaling, lipid metabolism, secondary metabolism, and nucleotide synthesis. In addition, 1,225 DEGs were annotated to 45 transcription factor gene families, including LFY, SBP, and MADS-box transcription factors closely related to flowering time. Weighted gene co-expression network analysis (WGCNA) showed that 16, 336, 446, and 124 DEGs have biological connections with Vrn1-5 A, Vrn3-7B, Ppd-1D, and WSOC1, respectively. Furthermore, TraesCS2D02G181400 encodes a MADS-MIKC transcription factor and is co-expressed with Vrn1-5 A, which indicates that this gene may be related to flowering time. Conclusions RNA-Seq analysis provided transcriptome data for the wheat heading date at key flower development stages of double ridge (W2.0) and androgynous primordium differentiation (W3.5). Based on the DEGs identified, co-expression networks of key flowering time genes in Vrn1-5 A, Vrn3-7B, WSOC1, and Ppd-1D were established. Moreover, we discovered a potential candidate flowering time gene, TraesCS2D02G181400. Taken together, these results serve as a foundation for further study on the regulatory mechanism of the wheat heading date.

Abstract It has long been known that the pollen shedding time in pine trees is correlated with temperature, but the molecular basis for this has remained largely unknown. To better understand the mechanisms driving temperature response and to identify the hub regulators of pollen shedding time regulation in Pinus tabuliformis Carr., we identified a set of temperature-sensitive genes by carrying out a comparative transcriptome analysis using six early pollen shedding trees (EPs) and six late pollen shedding trees (LPs) during mid-winter and at three consecutive time points in early spring. We carried out a weighted gene co-expression network analysis and constructed a transcription factor (TF) collaborative network, merging the common but differentially expressed TFs of the EPs and LPs into a joint network. We found five hub genes in the core TF module whose expression was rapidly induced by low temperatures. The transcriptional activity of this TF module was strongly associated with pollen shedding time, and likely to produce the fine balance between cold hardiness and growth activity in early spring. We confirmed the key role of temperature in regulating flowering time and identified a transcription factor module associated with pollen shedding time in P. tabuliformis. This suggests that repression of growth activity by repressors is the main mechanism balancing growth and cold hardiness in pine trees in early spring. Our results provide new insights into the molecular mechanisms regulating seasonal flowering time in pines.
