Photoperiodic flowering has been extensively studied in the annual short-day and long-day plants rice (Oryza sativa) and Arabidopsis (Arabidopsis thaliana), whereas less is known about the control of flowering in perennials. In the perennial wild strawberry, Fragaria vesca (Rosaceae), short-day and perpetual flowering long-day accessions occur. Genetic analyses showed that differences in their ...

The timing of the floral transition in Arabidopsis (Arabidopsis thaliana) is influenced by a number of environmental signals. Here, we have focused on acceleration of flowering in response to vegetative shade, a condition that is perceived as a decrease in the ratio of red to far-red radiation. We have investigated the contributions of several known flowering-time pathways to this acceleration....

Regulated RNA metabolism appears to be a critical component of molecular mechanisms directing flowering initiation in plants. A group of RNA binding proteins exerts their roles through the autonomous flowering pathway. Posttranscriptional mechanisms regulated by microRNAs (miRNAs) also play a key role in flowering-time control. Here, we demonstrate that the GIGANTEA (GI)-regulated miR172 define...

A pot experiment was conducted in a completely randomized design with five treatment and five replication, in each replication were 6 plants used. The study of zinc sulphate (ZnSO4) application (20 and 40 ppm) and Salicylic acid (SA) application (50 and 150 ppm) was compared to the control (distillated water) on growth and flowering Petunia hybrid. For each plant was used 10...

Tissue cultures of Phyllanthus tenellus Roxb. were maintained on modified MS to evaluate in vitro flowering under light of different qualities: white (control), blue, green, red, yellow, UV-A plus white and darkness; as well as different growth regulators at concentrations (μM): IBA 0.98, KIN 0.46, KIN 2.3, IBA 0.98 + KIN 0.46, IAA 1.14 + KIN 0.46. The events from vegetative to reproductive gro...

Variation in species' responses to abiotic phenological cues under climate change may cause changes in temporal overlap among interacting taxa, with potential demographic consequences. Here, we examine associations between the abiotic environment and plant-pollinator phenological synchrony using a long-term syrphid fly-flowering phenology dataset (1992-2011). Degree-days above freezing, precipi...

this experiment was conducted to determine gene action for different traits of chickpea including days to 50% flowering, days to maturity, plant height, 100-seed weight, number of primary branches, and number of pods per plant and seed yield since 2006 to 2009 in sararood dry land research sub institute in kermanshah. five genotypes arman, hashem, ilc588, iccv2 and ilc3279 were selected and cro...
