UGT87A2, an Arabidopsis glycosyltransferase, regulates flowering time via FLOWERING LOCUS C.

Numai utilizatorii înregistrați pot traduce articole

• Family 1 glycosyltransferases comprise the greatest number of glycosyltransferases found in plants. The widespread occurrence and diversity of glycosides throughout the plant kingdom underscore the importance of these glycosyltransferases. • Here, we describe the identification and

HISTONE DEACETYLASE6 interacts with FLOWERING LOCUS D and regulates flowering in Arabidopsis.

Numai utilizatorii înregistrați pot traduce articole

Histone acetylation and deacetylation play an important role in epigenetic controls of gene expression. HISTONE DEACETYLASE6 (HDA6) is a REDUCED POTASSIUM DEPENDENCY3-type histone deacetylase, and the Arabidopsis (Arabidopsis thaliana) hda6 mutant axe1-5 displayed a late-flowering phenotype.

Graft-transmissible action of Arabidopsis FLOWERING LOCUS T protein to promote flowering.

Numai utilizatorii înregistrați pot traduce articole

Day length perceived by a leaf is a major environmental factor that controls the timing of flowering. It has been believed that a mobile, long-distance signal called florigen is produced in the leaf, and is transported to the shoot apex where it triggers floral morphogenesis. Grafting experiments

Salicylic acid and the flowering gene FLOWERING LOCUS T homolog are involved in poor-nutrition stress-induced flowering of Pharbitis nil.

The short-day plants Pharbitis nil (synonym Ipomoea nil), var. Violet and Tendan were grown in a diluted nutrient solution or tap water for 20 days under long-day conditions. Violet plants were induced to flower and vegetative growth was inhibited, whereas Tendan plants were not induced to flower,

Overexpression of TCP8 delays Arabidopsis flowering through a FLOWERING LOCUS C-dependent pathway.

Numai utilizatorii înregistrați pot traduce articole

Flowering is a key process in the life cycle of plants. The transition from vegetative to reproductive growth is thus under sophisticated regulation by endogenous and environmental signals. The plant-specific Teosinte Branched 1/Cycloidea/Proliferating Cell Factors (TCP) family

Major flowering time gene, flowering locus C, regulates seed germination in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Flowering locus C (FLC) is a major regulator of flowering responses to seasonal environmental factors. Here, we document that FLC also regulates another major life-history transition-seed germination, and that natural variation at the FLC locus and in FLC expression is associated with natural

Flowering time modulation by a vacuolar SNARE via FLOWERING LOCUS C in Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

The transition of plant growth from vegetative to reproductive phases is one of the most important and dramatic events during the plant life cycle. In Arabidopsis thaliana, flowering promotion involves at least four genetically defined regulatory pathways, including the photoperiod-dependent,

Long-distance, graft-transmissible action of Arabidopsis FLOWERING LOCUS T protein to promote flowering.

Numai utilizatorii înregistrați pot traduce articole

Day length perceived by a leaf is a major environmental factor that controls the timing of flowering. It has been believed that a mobile, long-distance signal called florigen is produced in the leaf under inductive day length conditions, and is transported to the shoot apex where it triggers floral

FPF1 promotes flowering in Arabidopsis.

Numai utilizatorii înregistrați pot traduce articole

We have characterized the gene flowering promoting factor1 (FPF1), which is expressed in apical meristems immediately after the photoperiodic induction of flowering in the long-day plants mustard and Arabidopsis. In early transition stages, expression is only detectable in the peripheral zone of

Stress-induced flowering.

Numai utilizatorii înregistrați pot traduce articole

Many plant species can be induced to flower by responding to stress factors. The short-day plants Pharbitis nil and Perilla frutescens var. crispa flower under long days in response to the stress of poor nutrition or low-intensity light. Grafting experiments using two varieties of P. nil revealed

Arabidopsis inositol polyphosphate multikinase delays flowering time through mediating transcriptional activation of FLOWERING LOCUS C.

Numai utilizatorii înregistrați pot traduce articole

Timely flowering is critical for successful reproduction and seed yield in plants. A diverse range of regulators have been found to control flowering time in response to environmental and endogenous signals. Among these regulators, FLOWERING LOCUS C (FLC) acts as a central repressor of floral

Histone H2B monoubiquitination in the chromatin of FLOWERING LOCUS C regulates flowering time in Arabidopsis.

Numai utilizatorii înregistrați pot traduce articole

Ubiquitination is one of many known histone modifications that regulate gene expression. Here, we examine the Arabidopsis thaliana homologs of the yeast E2 and E3 enzymes responsible for H2B monoubiquitination (H2Bub1). Arabidopsis has two E3 homologs (HISTONE MONOUBIQUITINATION1 [HUB1] and HUB2)

ABSCISIC ACID-INSENSITIVE 4 negatively regulates flowering through directly promoting Arabidopsis FLOWERING LOCUS C transcription.

Numai utilizatorii înregistrați pot traduce articole

During the life cycle of a plant, one of the major biological processes is the transition from the vegetative to the reproductive stage. In Arabidopsis, flowering time is precisely controlled by extensive environmental and internal cues. Gibberellins (GAs) promote flowering, while abscisic acid

Flowering and determinacy in Arabidopsis.

Numai utilizatorii înregistrați pot traduce articole

Meristems provide new cells to produce organs throughout the life of a plant, and their continuous activity depends on regulatory genes that balance the proliferation of meristem cells with their recruitment to organogenesis. During flower development, this balance is shifted towards organogenesis,

Genetic analysis of early flowering mutants in Arabidopsis defines a class of pleiotropic developmental regulator required for expression of the flowering-time switch flowering locus C.

Numai utilizatorii înregistrați pot traduce articole

The Arabidopsis flowering-repressor gene FLOWERING LOCUS C (FLC) is a developmental switch used to trigger floral induction after extended growth in the cold, a process termed vernalization. In vernalized plants, FLC becomes transcriptionally silenced through a process that involves an epigenetic
