Challenges in studies on flowering time: interfaces between phenological research and the molecular network of flowering genes [PDF]

open access: yes, 2018
Flowering time is a well-studied subject in ecology, evolution and molecular biology. Long-term phenological studies have shown relationships between flowering time and environmental and endogenous factors in many species.

The genetic equidistance result of molecular evolution is independent of mutation rates [PDF]

open access: yes, 2008
The well-established genetic equidistance result shows that sister species are approximately equidistant to a simpler outgroup as measured by DNA or protein dissimilarity.

Evolution of size-dependent flowering in Onopordum illyricum: A quantitative assessment of the role of stochastic selection pressures [PDF]

open access: yes, 1999
We explore the evolution of delayed, size-dependent reproduction in the monocarpic perennial Onopordum illyricum, using a range of mathematical models, parameterized with long-term field data.

Joint QTL mapping and transcriptome sequencing analysis reveal candidate flowering time genes in Brassica napus L

open access: yesBMC Genomics, 2019
Background Optimum flowering time is a key agronomic trait in Brassica napus. To investigate the genetic architecture and genetic regulation of flowering time in this important crop, we conducted quantitative trait loci (QTL) analysis of flowering time ...

Flowering: a time for integration

open access: yesThe 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 ...

Multiparental mapping of plant height and flowering time QTL in partially isogenic sorghum families. [PDF]

open access: yes, 2014
Sorghum varieties suitable for grain production at temperate latitudes show dwarfism and photoperiod insensitivity, both of which are controlled by a small number of loci with large effects.

Phenological Gardens Protocol [PDF]

open access: yes, 2003
The purpose of this resource is to observe the flowering and leaf stages of selected garden plants throughout the year. After a phenological garden is planted, students observe the growth of leaves and blooming of flowers on the plants. These plants were

Flowering in time: genes controlling photoperiodic flowering inArabidopsis [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2001
Successful sexual reproduction in plants relies upon the strict coordination of flowering time with favourable seasons of the year. One of the most important seasonal cues for the model plantArabidopsis thaliana(Arabidopsis) is day length. Genes influencing flowering time inArabidopsishave been isolated, some of which are involved in the perception and
