We investigated the effects of catecholamine on flower-induction in P. nil (cv. Violet). GC-SIM analysis identified dopamine for the first time in P. nil seedlings. Dopamine levels in the cotyledons did not show a significant change during the inducing dark treatment. The dopamine content of cotyledons exposed to various durations of darkness were 0.1-0.2 nmol/g fresh weight. The same content w...

The transcription factor LEAFY is a master regulator of flowering and of flower development. It acts as a component of a switch that mediates the transition from the vegetative to the reproductive phase of plant development. Auxin is a plant hormone with many different roles in plant growth, including the induction of new primordia of both leaves and flowers at the shoot apex. We report that LE...

Experiments were conducted with containerized ;Tahiti' lime (Citrus latifolia Tan.) trees in order to define conditions needed to induce flowering. Cyclical or continuous water stress for 4 to 5 weeks induced flowering. Moderate (-2.25 megapascals, midday) or severe (-3.5 megapascals, midday) water stress as measured by leaf xylem pressure potential, for as little as 2 weeks induced flowering, ...

In the last 15 years, knowledge of the molecular and genetic mechanisms that underlie floral induction, floral patterning, and floral organ identity has exploded. Elucidation of basic mechanisms has derived primarily from work in three dicot species: Antirrhinum majus, Arabidopsis thaliana, and Petunia hybrida. Although Antirrhinum and petunia have contributed fundamental breakthroughs to our u...

Reprogramming of cell identities during development frequently requires changes in the chromatin state that need to be restricted to the correct cell populations. Here we identify an auxin hormone-regulated chromatin state switch that directs reprogramming from transit amplifying to primordium founder cell fate in Arabidopsis inflorescences. Upon auxin sensing, the MONOPTEROS transcription fact...

To increase our understanding of the genes involved in flower development in citrus, we identified genes differentially expressed between juveniles and adults of an early-flowering mutant of trifoliate orange (precocious trifoliate orange, Poncirus trifoliata L. Raf.) by suppressive subtractive hybridization (SSH) and macroarray hybridization analyses. Based on dot blot analysis, we confirmed t...

Through investigation on farmer, company and relevant bureau of local government, an analysis was conducted on organizational evolution of flower industrial cluster through induction and statistical methods. The research indicated that the organizational scale and structure had been unceasingly evolved during the process resulting in such industrial cluster. In recent years, the industrial clus...
