Summary: Plants have evolved intricate signaling pathways to perceive and respond to temperature, unlike animals who can avoid unfavorable conditions. While general acclimation processes occur throughout the whole plant, specific temperature responses are limited to certain tissues or cell types. Epigenomic analyses have been successful in understanding global responses, but more localized responses pose challenges due to inaccessibility of relevant chromatin. More research with higher spatiotemporal resolution is needed for future analyses.

Summary: This study identified 12 BrPEBP genes and focused on the functional analysis of BrFT-like genes. BrFT1 and BrFT2 promote flowering by upregulating the expression of floral meristem identity genes, while BrTSF and BrBFT have no clear effect on flowering. The study also revealed the importance of BrFT1 and BrFT2 in inflorescence organogenesis and the transition to flowering. The study provides insights into the functional diversity of BrFT-like homologs.

Summary: The FD gene in Arabidopsis plays a role in inducing flowering by interacting with the FT gene. Similarly, two FT homologs in Platanus acerifolia, PaFT and PaFTL, are involved in diverse developmental processes. The closely related FD homologs, PaFDL1 and PaFDL2, were found to have maximal expression levels during floral transition and undergo post-transcriptional alternative splicing. Overexpressing different transcript forms in tobacco resulted in accelerated floral initiation and abnormal flowers, suggesting a role for the PaFDL proteins in floral development.

Summary: The study identified florigen gene variants FT2a and FT5a in soybeans, which delay flowering time under short-day conditions and increase yield. Additionally, it was found that FT2a and FT5a variants have diverse origins and played distinct roles as soybean spread to lower latitudes.

Summary: The transition from vegetative to inflorescence shoot apical meristem is a key developmental switch in flowering plants, modulated by various stimuli and controlled by regulatory networks. FT and TFL1, as major components of florigen, play universal and multifaceted roles in plant development, with modulations of their pathways having a considerable impact on plant reproductive success. Their functional conservation and divergence in various plant species are discussed, highlighting their important roles in plant development and crop domestication.

Summary: FT-like genes play a crucial role in regulating flowering time in angiosperm plants. In barley, the HvFT4 gene specifically delays flowering time and suppresses reproductive development, impacting spikelet formation and grain yield. Understanding the genetic basis of FT-like genes can lead to novel breeding strategies for improving barley productivity.

Summary: Flowering time is crucial for plant reproductive success and is influenced by floral bud differentiation and development time. This study investigated the floral bud development of spring and autumn-flowering Pleione species through continuous anatomical observations. The transition from vegetative to reproductive growth occurred in June for both types, but the spring-flowering species had a longer dormancy period, resulting in a longer time from bud initiation to flowering compared to the autumn-flowering species. These findings have implications for breeding new varieties and regulating flowering time in horticultural production, as well as enhancing our understanding of flowering time evolution in related species.

Summary: A comprehensive study was conducted on Ma bamboo to understand the molecular regulatory mechanism of bamboo flowering. The results identified differentially expressed genes related to the flowering pathway, with DlFT1 being a candidate gene that promotes flowering in bamboo. These findings provide a better understanding of the roles of florigen genes in bamboo and have implications for regulating bamboo flowering in the future.
