Environmental control of rice flowering time

Plant Communications, 2023
Correct measurement of environmental parameters is fundamental for plant fitness and survival, as well as for timing developmental transitions, including the switch from vegetative to reproductive growth. Important parameters that affect flowering time include day length (photoperiod) and temperature. Their response pathways have been best described in

Olive phenology as a sensitive indicator of future climatic warming in the Mediterranean [PDF]

, 2000
Experimental and modelling work suggests a strong dependence of olive flowering date on spring temperatures. Since airborne pollen concentrations reflect the flowering phenology of olive populations within a radius of 50 km, they may be a sensitive ...

Diversification of flowering plants in space and time

Nature Communications, 2023
The rapid diversification and high species richness of flowering plants is regarded as ‘Darwin’s second abominable mystery’. Today the global spatiotemporal pattern of plant diversification remains elusive.

BEE FLOWERS: A HYPOTHESIS ON FLOWER VARIETY AND BLOOMING TIMES [PDF]

Evolution, 1975
In arctic (Kevan, 1972), temperate (Lovell, 1903), and tropical regions, the flowers of different species of plants in a given habitat at any one time usually exhibit a variety of colors, scents, morphologies, and blooming times. Bees are the primary pollinators of many of them (Baker and Hurd, 1968).

TEMPRANILLO is a regulator of juvenility in plants [PDF]

, 2014
Many plants are incapable of flowering in inductive daylengths during the early juvenile vegetative phase (JVP). Arabidopsis mutants with reduced expression of TEMPRANILLO (TEM), a repressor of FLOWERING LOCUS T (FT) had a shorter JVP than wild-type ...

Topographic heterogeneity lengthens the duration of pollinator resources

Ecology and Evolution, 2020
The availability of sufficient and diverse resources across time is important for maintenance of biodiversity and ecosystem functioning. In this study, we examine the potential for variation in environmental conditions across topographic gradients to ...

Apomictic development during different flower development stages in Crataegus tanacetifolia (Lam.) Pers., endemic to Turkey

Notulae Scientia Biologicae, 2021
In this study, aposporic apomictic development and its relation to the different flower development stages were investigated by light and fluorescence microscopy in Crataegus tanacetifolia (Lam.) Pers. (Rosaceae). At pre-anthesis stage, aposporic initial

A Time to Grow, a Time to Flower [PDF]

The Plant Cell, 2005
Flowering is one of the most critical timing decisions for higher plants because it can determine the difference between reproductive success and failure. The transition from vegetative growth to flowering is controlled by a complex network of interconnected pathways influenced by ...

The role of BoFLC2 in cauliflower (Brassica oleracea var. botrytis L.) reproductive development [PDF]

, 2014
In agricultural species that are sexually propagated or whose marketable organ is a reproductive structure, management of the flowering process is critical.

Flowering: a time for integration

The International Journal of Developmental Biology, 2005
Flowering time is under the control of multiple environmental cues such as photoperiod and exposure to cold temperatures (vernalization). A few regulators named integrators of flowering time signals (LEAFY, SOC1 /AGL20 and FT ) integrate inputs from the different flowering cascades and convey the resulting outcome to floral meristem identity genes at ...
