In this paper we show how inter-cellular molecular communication may change the overall levels of photosynthesis in plants. Individual plant cells respond to external stimuli, such as illumination levels, to regulate their photosynthetic output. Here, we present a mathematical model which shows that by sharing information internally using molecular communication, plants may increase overall photosynthate production. Numerical results show that higher mutual information between cells corresponds…

Information Theoretic Based Comparative Analysis of Different Communication Signals in Plants
TLDR
Better communication performance can be achieved by electro-chemical signals as compared to mechanosensitive signals based on the propagation mechanism, and it is found that a short refractory period leads to higher mutual information and propagation speeds.
Communication in Plants: Comparison of Multiple Action Potential and Mechanosensitive Signals With Experiments
TLDR
For multiple action potentials for a long chain of cells in different configurations, and the study of multiple mechanosensitive activation signals (generated due to a mechanical stimulus) in plants, it is found that the mutual information per cell and information propagation speed tends to increase up to a certain number of receiver cells.
Plant behaviour: a mathematical approach for understanding intra-plant communication
TLDR
A fully coupled system of nonlinear, non-autonomous, discontinuous, ordinary differential equations to describe with accuracy the adapting behaviour and growth of a single plant, by deeply analysing the main stimuli affecting plant behaviour is proposed.
Communication and Information Theory of Single Action Potential Signals in Plants
TLDR
A reaction–diffusion model of individual AP signals is considered to analyze APs from a communication- and information-theoretic perspective, and it is shown that the presence of an AP signal can increase the mutual information and information propagation speed among neighboring cells with receivers in different settings.
Arabidopsis plants perform arithmetic division to prevent starvation at night
TLDR
This work finds that the rate of decrease of starch reserves in Arabidopsis leaves is adjusted to accommodate variation in the time of onset of darkness and starch content, such that reserves last almost precisely until dawn.
Parameters of electrical signals and photosynthetic responses induced by them in pea seedlings depend on the nature of stimulus.
TLDR
Investigating parameters of VP induced by burning, heating and mechanical injury in pea seedlings and a theoretical analysis of the mechanisms underlying the differences in VP parameters suggest that differences in photosynthetic responses may be determined by the parameters of VPs induced by stimuli of different nature.
Variation potential propagation decreases heat-related damage of pea photosystem I by 2 different pathways
TLDR
The results suggest the possibility of 2 different pathways of VP-induced decrease of heat-related PSI damage, which are related to or not related to PSII activity.
How plants manage food reserves at night: quantitative models and open questions
TLDR
The process of night-time starch degradation necessitates a fundamental metabolic role for the circadian clock and, more generally, highlights how cells process information in order to optimally manage their resources.
Molecular Communications With Molecular Circuit-Based Transmitters and Receivers
TLDR
This paper derives an expression of mutual information and uses it for numerical maximization in a parameterized transmitter circuit and shows that the circuit is able to give mutual information that is close to upper bound obtained in earlier work.
Using spatial partitioning to reduce receiver signal variance in diffusion-based molecular communication
TLDR
It is shown that a spatially partitioned system gives a lower total output signal variance than one that does not use partitioning, especially in steady state.
