Plants or plant organs were photographed and typical images are shown in panels A-E. A Tomato plants inoculated with CMV-PV at the seedling stage show marked stunting right compared to mock-inoculated plants left. B Mature, expanded leaves of infected left and mock-inoculated right plants.

Bees spent longer buzz-pollinating sonicating flowers on CMV-infected tomato plants. Single bees were released into the flight arena containing three mock-inoculated and three CMV-infected flowering tomato plants Fig 6 ; S8 Fig.

The time each bee spent buzz-pollinating its first five choices of flower was measured using a stopwatch. Sensitivity analysis showing discrete time exponential growth rates for a rare mutant type of plant in the vicinity of the equilibrium from which that type is absent.

A Growth rate of resistant mutants in the vicinity of the 0,0,1 equilibrium at which only susceptible plants are present. The panel shows a series of full two-way sensitivity analyses of the model, showing effects on the growth rate of rare mutant resistant plants in the vicinity of the equilibrium at which only susceptible plants are present, caused by independently changing pairs of parameters all other parameters fixed.

All pair-wise combinations of two parameters are shown: In all cases, the magnitude of the largest Eigenvalue of the Jacobian matrix at the model equilibrium—which is equivalent to the initial discrete time rate of exponential growth over successive seasons of rare mutant resistant plants -is shown by color.

Note that Fig 8 in the main text characterises long-term evolutionary outcomes by distinguishing regions in which growth rates of each type of mutant are larger than or smaller than one, and so in which the equilibria can be invaded or not: B Growth rate of susceptible mutant plants in the vicinity of the 1,0,0 equilibrium at which only homozygous resistant plants are present all other details as per Panel A.

Design of free choice bee-pollination experiment. A A large flight arena x x 90cm: H x W x D was constructed out of nylon netting with three zipped doors to allow full access. Sliding gates on the side of the small arena permitted one bee to be released into the larger arena containing three mock-inoculated and three cucumber mosaic virus CMV -infected flowering tomato plants.

One of main problems deterring the establishment of cooperation between species is the existence hidden characteristics due to information asymmetry 1: Specifically, plants often conceal the reward e.

Signalling could provide a mechanism to solve this problem 1. In signalling game between plants and pollinators, honest signals are those that are positively correlated with the amount of rewards. The most honest signalling is the direct and conspicuous display of the reward itself 3. The floral traits that are uncoupled from the rewards within flowers could be as honest signals to advertise rewards for pollinators. The floral signals positively correlated with the amount of rewards have been documented for floral colour changes after post-pollination 78the size of petals and corolla-tube diameters in Silene virginica 9corolla tube length in Erysimum mediohispanicum 10petal length in Turnera ulmifolia 11symmetrical flowers in Epilobium angustifolium 12bract size in Dalechampia ipomoeifolia 13and floral scent in Brassica rapa In plant-pollinator signalling game, the central question is how the honest signals have been established when the interests of signallers and receivers conflict partly.

On the one hand, because floral signals and rewards are uncoupled within one flower, plants could reduce the cost by sending dishonest signals signals with low correlation to the amount of rewards According to costly signaling theory 16 — 18the cost of signals is an essential element for stable honest signaling in any signalling scenario and it thus extends to the plant-pollinator interactions.

If the benefits for low and high quality signallers are same, the effectiveness of signalling depends on the strength of the correlation between the cost and the quality desired by the receiver: When the signal has a cost, only good quality individuals will find it profitable to advertise their quality, therefore the signal will be honest.

On the other hand, pollinators usually rely on floral signals to assess the amount of rewards. The foraging behaviour of pollinators could lead to the honest signals offered by plants though repeated interactions with plants. Pollinators, such as bumble bees, not only learn positive or adverse associations between floral signals and rewards 20but also gather the information about reward amount and use this information to improve their subsequent foraging efficiency in repeated interactions with plants 21 — The pollinators could remember the most profitable patches, and return preferentially to these The experienced pollinators, Bombus ignitus, could discriminate between rewarding and less-rewarding plants and return more frequently to plants providing high amounts of reward Bombus impatiens follow a Bayesian updating process to assess the degree of correlation between flower signals and rewards When pollinators could update the information about signal-reward relationship based on past experiences, the foraging behaviour of pollinators could limit the dishonest signals in by a preference for honest ones correlated to rewards in T.

The hawkmoth pollinators, Manduca sexta, can make the adjustment of probing time in response to nectar volume, and that the self-serving pollinator behaviour can reduce probing duration and in low-nectar plants, resulting in reduced seed production The interaction frequency could determine the effect of the foraging behaviour of pollinators on plants. However, it is still not clear whether the cost of signals combined with foraging behaviour of pollinators could make the honest signaling to be a stable equilibrium in the repeated plant-pollinator signalling game.

In this study, we investigated theoretically the establishment of honest signals in repeated two-type Spence signalling game between plants and pollinators. The Spence signalling game captures the central feature of signalling game that strategic costs associated with signalling are required for honest signalling in the presence of partial conflict of interest The Spence signalling game belongs to the family of the differential cost games such as Zahavi 16 and Grafen 17in which one type pays lower signalling costs than the other while both types gain the same benefits.

  • The signalling game between plants and pollinators

In our repeated signalling game, we assume that plants with different quality have different signalling cost and that they also provide different benefit for pollinators. In each visiting bout, the plants could either send the signal or not.
