There and back again: An evolutionary perspective on long-distance coordination of plant growth and development.
Cara D. Wheeldon,Tom Bennett +1 more
TL;DR: This review discusses the puzzlingly sparse evidence for auxin as a shoot-to-root signal, the evolutionary re-purposing of strigolactones and gibberellins as hormonal signals, and speculate on the possible role of sugars as long-distance signals.

Environmental strigolactone drives early growth responses to neighboring plants and soil volume in pea
TL;DR: In this paper , the authors show that peas detect neighbors early in the life cycle through their root systems, resulting in strong changes in shoot biomass and branching, and that this requires SL biosynthesis.

Wheat plants sense substrate volume and root density to proactively modulate shoot growth
TL;DR: In this article, the authors show that wheat plants proactively modulate their shoot growth with respect to substrate volume, independent of nutrient availability, and that these effects occur in two phases; in the first phase, the dilution of a mobile "substrate volume-sensing signal" (SVS) allows plants to match their shoot (but not root) growth to the total size of the substrate, irrespective of how much of this they can occupy with their roots.

Integrated dominance mechanisms regulate reproductive architecture in Arabidopsis thaliana and Brassica napus
TL;DR: In this article, the authors investigate the spatio-temporal control of reproductive architecture in Arabidopsis (Arabidopsis thaliana) and Brassica napus and propose that these feedbacks represent an integrated dominance mechanism that allows resource use to be correctly sequenced between developmental stages to optimise seed set.

Root density sensing allows pro-active modulation of shoot growth to avoid future resource limitation
TL;DR: It is shown that shoot growth scales directly with soil volume, independently of the nutritional content of the soil, and that plants can become ‘volume restricted’ even in the presence of abundant resources.
