• Background Maize ( Zea mays ) forms a complex root system comprising embryonic and post‐embryonic roots. The embryonically formed root system is made up of the primary root and a variable number of seminal roots. Later in development the post‐embryonic shoot‐borne root system becomes...
• Background and Aims The stomata are a key channel of the water cycle in ecosystems, and are constrained by both physiological and environmental elements. The aim of this study was to parameterize stomatal conductance by extending a previous empirical model and a revised Ball–Berry model....
• Background and Aims Acclimation of photosynthesis to light and its connection with canopy nitrogen (N) distribution are considered. An interpretation of a proportionality between light‐saturated photosynthesis and local averaged leaf irradiance is proposed by means of a simple model. •...
• Background and Aims Raphides are ubiquitous in the palms (Arecaceae), where they are found in roots, stems, leaves, flowers and fruits. Their occasional presence in embryos, first noticed over 100 years ago, has gone largely unexamined. • Methods Embryos from 148 taxa of palms, the largest...
• Background and Aims The number of genera included in Apocynaceae subfamily Periplocoideae is a matter of debate. DNA sequences are used here as an independent dataset to clarify generic relationships and classification of the tuberous periplocoid genera and to address the question of the...
• Background and Aims Most Vaccinium species have strict soil requirements for optimal growth, requiring low pH, high iron availability and nitrogen primarily in the ammonium form. These soils are limited and are often located near wetlands. Vaccinium arboreum is a wild species adapted to a...
• Background and Aims Stem shape in angiosperms depends on several growth traits such as elongation direction, amount and position of axillary loads, stem dimensions, wood elasticity, radial growth dynamics and active re‐orientation due to tension wood. This paper analyses the relationship...
In a recent ‘Invited Review’, I stated the case for plant intelligence, provided definitions and outlined some of the consequences, illustrating them with examples. A short critique of this concept by Firn is given in the preceding ‘Viewpoint’ and rebuttals of the criticisms it contains...
• Background and Aims The relationship between composition and structure of plant primary cell walls, and cell mechanical properties is not fully understood, partly because intrinsic properties of walls such as Young’s modulus cannot be obtained readily. The aim of this work is to show that...
