The development of the 3D shape of an is complex, and the contributions of underlying pathways are difficult to untangle. Battu et al. decouple the organ size and organ shape by conducting a thorough quantification of organ geometry in 3D together with Principle Component Analysis (PCA), and using the…

Plants fix carbon dioxide to generate biomass, and in many cases increasing the availability of CO2 enhances plant growth. However, some studies have shown that although yields of food crops such as rice might increase, their nutritional value decreases, due to limitations in availability of minerals…

As a writer and an editor, I am horrified by the idea that thinking can be replaced by artificial intelligence. But I do recognize that deep learning / machine learning / artificial intelligence can provide major opportunities for data analysis, as eloquently described in this review article by Murphy…

The establishment of adaxial-abaxial polarity during the growth of the leaf primordium is a prerequisite for the formation of the flat, thin leaves observed in most (but not all) plants. The micro-RNAs tasiARF and miR165/6, which form concentration gradients within leaf primordia, are major contributors…

Stomata are pores on the surface of leaves essential for gas exchange. In grasses, stomatal aperture is controlled by pairs of dumbbell shaped guard cells, with each guard cell surrounded by a subsidiary cell. Despite cell geometry being well described, it was unclear how it influences stomata function.…

Machine Learning (ML) is described by Wikipedia as ‘the study of computer algorithms that can improve automatically through experience and by the use of data’. In agronomy, machine learning can predict important crop traits (including yield) by analysing the large datasets such as data generated…

Stomatal guard cells control both carbon dioxide uptake and transpirational water loss. Guard cell control over the stomatal pore  aperture is sensitive to water status (through ABA) as well as the amount of CO2 available within the leaf air space. Several studies have indicated that stomatal aperture…

Genetic studies have provided us with countless examples of regulatory switches that transduce a signal into a response. Mutant analysis is usually sufficient to identify these controlling elements, but often in an all-or-nothing way. Here, Ghusinga et al. have taken a theoretical kinetic approach to…
