“…In Geranium refractum , it has been reported that the downward-facing floral orientation enhances pollen transfer [ 14 ]. Similar patterns of changes in floral orientation in Corydalis sheareri have been reported to affect pollination efficiency [ 15 ]. Interestingly, Desmodium setigerum shows a unique ability of reversing its flower colour and shape in case they are not effectively pollinated [ 16 ].…”

Flowers of Trifolium repens L. show recurving. We, therefore, studied whether this is an effective strategy employed by the species to augment reproduction. For this, fifty plants of the species were tagged and monitored. This included twenty control and twenty constrained to recurve. The remaining 10 plants were covered with a net to limit cross-pollination. Daily observations on the plants were recorded. No significant difference in the number of flowers per inflorescence between control and constrained plants was found. However, a significant difference (p < 0.001) in the number of seeds produced by control (68.35 ± 3.92) and constrained plants (22.25 ± 1.35) was observed. Three times more seeds, without compromising on seed mass (p > 0.05), were produced in the control plants. No seeds were produced in the flowers that were netted. Thus, recurving appears to help T. repens in reproduction.

Unlike most crops, which were domesticated through long periods of selection by ancient humans, horticultural plants were primarily domesticated through intentional selection over short time periods. The molecular mechanisms underlying the origin and spread of novel traits in the domestication process have remained largely unexplored in horticultural plants. Gloxinia (Sinningia speciosa), whose attractive peloric flowers influenced the thoughts of Darwin, have been cultivated since the early 19th century, but its origin and genetic basis are currently unknown. By employing multiple experimental approaches including genetic analysis, genotype–phenotype associations, gene expression analysis, and functional interrogations, we showed that a single gene encoding a TCP protein, SsCYC, controls both floral orientation and zygomorphy in gloxinia. We revealed that a causal mutation responsible for the development of peloric gloxinia lies in a 10-bp deletion in the coding sequence of SsCYC. By combining genetic inference and literature searches, we have traced the putative ancestor and reconstructed the domestication path of the peloric gloxinia, in which a 10-bp deletion in SsCYC under selection triggered its evolution from the wild progenitor. The results presented here suggest that a simple genetic change in a pleiotropic gene can promote the elaboration of floral organs under intensive selection pressure.

“…The different height treatment flowers were at angles because of the weight of the taller stems inching forward, while the same height flowers stood upright in the same horizontal positions. Floral orientation is thought to affect pollinator attraction, foraging behavior, and pollen transfer (Wang et al, 2014). However, previous studies are on species of plants that produce single flowers, and rather little is known about the effect of floral orientation on pollination in more multifaceted inflorescences.…”

Height differences in clonal stands ofTussilago farfarapromote outcrossing by influencing pollinator behaviour

7Plants with mixed mating systems balance the advantages of selfing and the costs of inbreeding. 8 Previous studies have shown that plant species with the ability to self-pollinate and cross 9 pollinate have strategies to promote outcrossing to increase genetic diversity. Various features of 10 floral morphology are thought to be deliberate mechanisms to manipulate plant mating systems. I 11 hypothesized that within-plant variation in flower stem height is a morphological trait that can 12 reduce geitonogamy by increasing pollinator movement among plants. This hypothesis was 13 tested using coltsfoot (Tussilago farfara); coltsfoot plants host several flowering stems that differ 14 in height, with each stem having a single, terminal flowerhead. I used cut flowers to create 15 'populations' of coltsfoot in which each plant had four inflorescences with equal or unequal 16 flower stalk lengths and measured frequency of insect pollinators that would stay among flowers 17 within a plant or move to other plants. All pollinators (bee flies, hover flies, solitary bees and 18 wasps) showed a marked discrimination in favor of leaving plants with flowers of different 19 heights and stayed when plants had flowers of the same height. This study shows that variation 20 in flower heights is important for reducing geitonogamy in coltsfoot and suggests that the 21 evolution of this morphological trait should be considered in studies of mating systems.22
