Summary: This study elucidates the important roles of JcFT and JcLFY in flowering transition and floral organ development in Jatropha, as well as their relationship. JcFT is the central gene for floral meristem transition, while JcLFY is the key gene for floral and inflorescence development.

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: This study investigates the role of miRNAs in the acquisition of reproductive competence in plants. The results show that miR156/miR157 regulate the timing of vegetative phase change, while miR172 has a minor role in vegetative phase change but a major effect on reproductive competence.

Summary: MdTFL1, a floral repressor in apple, forms complexes with multiple proteins and competes with MdFT1 in regulating reproductive development. MdTFL1 and MdFT1 exhibit similar interaction patterns, suggesting possible antagonistic roles in flowering regulation. The identification of hundreds of novel interaction proteins of MdTFL1 through yeast two-hybrid screens expands the floral regulatory network and introduces new roles for TFL1 in plant development.

Summary: In this study, the genotyping of 310 Brassica rapa accessions revealed 19 homozygous and 81 heterozygous putative functional alleles of the flowering time gene BrFLC5. Overexpression of BrFLC5 was found to regulate flowering in Arabidopsis thaliana. The expression level of BrFLC5 was not associated with the G/A polymorphism in the third intron, but rather with a 584-bp insertion in the promoter region. The potential impact of high expression of functional BrFLC5 on premature bolting-resistant lines in B. rapa vegetables is discussed.

Summary: Madonna lily is a flowering geophyte that grows wild in Israel and the neighboring region, with great commercial potential as an ornamental crop. This study found that low temperature can accelerate flowering in Madonna lily, while day length has minimal effect. Additionally, bulb exposure to cold may delay flowering until the following season, depending on the developmental stage of the shoot apical meristem.

Summary: Single-nucleus RNA sequencing combined with mRNA hybridization identified key genes involved in floral initiation in litchi apical buds. The analysis of 41,641 nuclei revealed 35 cell clusters and proposed a model profiling the key events associated with litchi floral meristem identity. Interestingly, the transportability of FT and TFL1 mRNA from leaf to shoot apical meristem was proposed based on hybridization results. These findings provide insights into the molecular events during litchi floral transition and the identification of new regulators.

Summary: Evolutionarily conserved microRNAs with high copy numbers in the genome play important roles in regulating plant developmental transitions. Utilizing CRISPR-Cas9 technology, the study investigated the functions of all 5 members of the MIR172 family in Arabidopsis, revealing their distinct expression patterns and functional specificity in various developmental processes. The findings highlight the spatiotemporal changes in gene expression that underlie evolutionary novelties of microRNA gene families in nature.

Summary: By studying the key flowering-time gene FLC in precocious walnuts, it was found that FLC was specifically expressed during the bud dormancy stage of precocious walnut and its expression gradually decreased as the ambient temperature warmed. Overexpression of JrFLC in Arabidopsis thaliana delayed flowering and increased the total leaf number, suggesting that JrFLC also functions as a floral repressor in walnut and other plants.
