The phosphatidylethanolamine-binding protein (PEBP) gene family exists in all eukaryote kingdoms, with three subfamilies: (FLOWERING LOCUS T)-like, (TERMINAL FLOWER 1)-like, and (MOTHER OF FT AND TFL1)-like. genes promote flowering, genes act as a repressor of the floral transition, and genes have functions in flowering promotion and regulating seed germination. We identified and characterized orthologs of the / gene family in petunia to elucidate their expression patterns and evolution. Thirteen /-like genes were isolated from petunia, with the five -like genes mainly expressed in leaves. The circadian rhythms of five -like genes and (petunia CONSTANS ortholog) were figured out. The expression of was contrary to that of , , , and . had a circadian clock different from , but coincided with ; it decreased in daytime and accumulated at night. Two of the -like genes with differential circadian rhythm and higher expression levels, and , were used to transform . Eventually, overexpressing strongly delayed flowering, whereas overexpression of produced extremely early-flowering phenotype. Different from previous reports, , , and were relatively highly expressed in roots. Taken together, this study demonstrates that petunia -like genes, like , are able to respond to photoperiod. The expression pattern of / gene family in petunia contributes to a new insight into the functional evolution of this gene family.

During the transition to the reproductive phase, the shoot apical meristem switches from the developmental program that generates vegetative organs and instead produces flowers. In this study, we exam...
Genes in the FLOWERING LOCUS T (FT) family integrate external and internal signals to control various aspects of plant development. In soybean (Glycine max), FT2a and FT5a play a major role in floral ...
Comparative RNA-sequencing and DNA methylation analyses of apple (Malus domestica Borkh.) buds with diverse flowering capabilities reveal novel insights into the regulatory mechanisms of flower bud formation.
In plants, DNA methylation (i.e., chromatin modification) is important for various biological processes, including growth, development, and flowering. Because 'Fuji' apple trees are alternate bearing ...
The life cycles of plants are characterized by two major life history transitions-germination and the initiation of flowering-the timing of which are important determinants of fitness. Unlike annuals,...
An orthologous gene of SEPALLATA1, designated as IiSEP1, was isolated from Isatis indigotica. The genomic DNA of IiSEP1 is 3.1 Kb in length. The full-length cDNA of IiSEP1 is 1481 bp and contains a ...

Lung cancer is a leading cause of cancer mortality among adults worldwide. The incidence rates of lung cancer among never smoking females in some parts of East Asia are among the highest i...
The research involves the establishment of a cohort including as much as possible cases of macrothrombocytopenia related to a "MYH9 syndrome" and the study of mutations and polymorphisms o...
Mirror movements are involuntary, symmetrical and simultaneous movements occurring on one side of the body that accompany controlateral voluntary movements. Congenital mirror movements (CM...
This study will look for new types of gene changes that may be related to cancer in some patients. Some gene changes (mutations) are passed on from parents to offspring (child). Other gene...
Tops of plants when in flower, including the stems, leaves and blooms.
An order of dicotyledonous flowering plants which includes six families. It is best known for its ornamental plants such as LONICERA (honeysuckle), VIBURNUM (arrowwood and guelder rose), and SCABIOSA (scabious, or pincushion flower).
Identification of individuals who are heterozygous at a GENETIC LOCUS for a recessive PHENOTYPE.
The loss of one allele at a specific locus, caused by a deletion mutation; or loss of a chromosome from a chromosome pair, resulting in abnormal hemizygosity. It is detected when heterozygous markers for a locus appear monomorphic because one of the ALLELES was deleted. When this occurs at a tumor suppressor gene locus where one of the alleles is already abnormal, it can result in neoplastic transformation (CELL TRANSFORMATION, NEOPLASTIC).
A plant family of the order Gentianales, subclass Asteridae, class Magnoliopsida. They have leaflike appendages at the base of the leafstalks, have terminal flower clusters. Petals have four or five overlapping lobes and the fruit is a capsule containing winged or wingless seeds.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
