Summary: Selective pressures from herbicides have led to genetic changes in physiological traits of weeds, such as flowering time. The PfAGL28 gene isolated from herbicide-resistant weeds plays a crucial role in early flowering and pod formation. Overexpression of PfAGL28 in Arabidopsis thaliana resulted in early-flowering phenotype, providing insights into the flowering mechanisms of herbicide-resistant weeds.

Summary: This study systematically identified and characterized MADS-box genes in Iris laevigata, a plant species with beautiful flowers and strong cold resistance. The researchers found 41 putative MADS-box genes and selected IlSEP3 and IlSVP for functional studies. They showed that IlSEP3 promotes flowering, while IlSVP does not significantly affect phenotypes. This work fills the knowledge gap in key flowering control genes in I. laevigata and provides insights into the genetic regulation of flowering time in this plant species.

Summary: The study demonstrates that MSI1 and HDA6 interact to repress flowering time control genes through histone modifications. HDA6-mediated H3K9 deacetylation is dependent on MSI1, while H3K27Me3 mediated by PRC2 containing MSI1 is also dependent on HDA6. The findings reveal the crucial role of the HDA6-MSI1 module in mediating the interaction between histone deacetylation and H3K27Me3 to repress gene expression.

Summary: The photoperiod response gene Ppd-H1 interacts with drought stress signals to modulate spike development in barley. Wild-type Ppd-H1 allele can mitigate the negative effects of drought on barley growth and spike development. The genetic differences in developmental response to drought are correlated with the differential down-regulation of flowering promotors in barley.

Summary: In this study, two MADS-box genes (LsAG2 and LsDEF1) in L. speciosa were isolated, and their overexpression in Arabidopsis thaliana resulted in different phenotypes and the up-regulation of endogenous genes related to flowering. These findings provide a theoretical basis for understanding the flowering time, flower development, and genetic improvement of double-petaled flowers in the genus of Lagerstroemia.

Summary: NLP6 and NLP7 act as activators in nitrate signaling and repressors under ammonium conditions to regulate different genes. Nuclear localization and nucleocytosolic shuttling of NLP6 and NLP7 are independent of each other. NLP6 and NLP7 play a more dominant role in the response to high nitrate.

Summary: There have been successful studies that have sped up the flowering cycle in woody perennial horticultural species. In one study, a gene from silver birch was used to accelerate flowering in apple, and similar results were achieved in European pear. These transformed pear lines were able to flower and produce fruit within a short period of time, showing potential for use in rapid breeding programs.

Summary: The CmFL1 gene in chrysanthemums plays a crucial role in controlling flowering time and inflorescence meristem development. Overexpression of CmFL1 leads to early flowering, while suppression of CmFL1 expression increases floret numbers. Furthermore, CmFL1 regulation also affects other genes involved in flowering and inflorescence meristem development.

Summary: In this study, we identified and characterized MADS-box genes involved in the regulation of flowering time in Davidia involucrata, a deciduous perennial tree. Two key genes, DiMADS-1 and DiMADS-2, were found to be specifically expressed during flower development in Davidia involucrata. Transgenic experiments showed that DiMADS-1 promoted early flowering while DiMADS-2 delayed flowering and inhibited plant growth. These findings provide valuable insights into the molecular mechanisms underlying flowering time regulation in Davidia involucrata.

Summary: In this study, the DNA-binding profile of the MADS-domain protein SEPALLATA3 was investigated using SELEX-seq, revealing a novel DNA-binding mode and a preference for AT-rich flanking motifs. The highly conserved arginine residue in the DNA-binding domain was found to play a crucial role in nucleotide recognition, particularly at specific positions within the CArG-box motif. These findings suggest a unique DNA-binding specificity for SEPALLATA3 compared to other MADS-domain proteins.

Summary: The study identified the evolutionary stages and expansion of NAC transcription factors in green plants, particularly in hexaploid wheat. The results showed that tandem replications during polyploidization play a significant role in increasing the number of NAC transcription factors in wheat. Additionally, the analysis of TaNACs in wheat revealed distinct groups and clusters, indicating the presence of neofunctionalization and subfunctionalization genes which are important in responding to various stresses.

Summary: In this study, 15 SINA-type E3 ubiquitin ligases were identified and cloned from wheat. The transcription level of TaSINA2B was significantly induced by drought, osmotic, and abscisic acid treatments. Wheat with the TaSINA2B promoter showed higher drought tolerance and gene expression levels, mainly due to a 64 bp insertion in its promoter. TaSINA2B-overexpressing transgenic wheat lines exhibited enhanced drought tolerance through promoting root growth. An interaction between TaSINA2B and TaSINA1D was also detected. TaSINA1D-overexpressing transgenic wheat lines showed similar drought tolerance and root growth phenotype to those observed when TaSINA2B was overexpressed.

Summary: In this study, a diversity panel of wheat accessions was used to analyze and examine the genetic variation in grain copper content. Twelve candidate genes associated with grain copper content were identified through a genome-wide association study, and three of them were considered to be important for wheat grain. Additionally, the study found that grain copper content gradually decreased with release years among wheat accessions in China, and was influenced by yield factors.

Summary: This study investigated the effect of steam explosion (SE) treatment on the soluble dietary fiber (SDF) content of wheat bran, finding a significant increase in total SDF content after treatment. The molecular weight of SDF decreased and the surface became disintegrated, while thermodynamic characteristics improved and similar functional groups were identified. These effects may enhance the physicochemical properties of SDF and increase the application value of wheat bran.
