The Node’s ‘a day in the life of a ...’ series is designed to give insights into the working of the labs – and the people – that try to unravel development,
If you’re a plant what is the best way to defend yourself, given that you can’t run from attackers? I’ve had a think and I went for being massive, with armour-planting, spikes, thorns and stings, along...
The optimal defence hypothesis (ODH) predicts that tissues that contribute most to a plant’s fitness and have the highest probability of being attacked will be the parts best defended. In general, young tissues show...
Over-expression of the cell cycle checkpoint gene, WEE1, may repress growth and development. Spadafora et al. culture explants of Arabidopsis thaliana from an over-expressing Arath;WEE1 line (WEE1oe), two T-DNA...
The long-held notion that the sporophyte shoot is homologous with the seta of mosses has been questioned, but no alternative evolutionary model has hitherto been proposed. Ligrone et al. explore the origin of the...
Austrobaileya has long served as a model for ancient angiosperm pollen structure. Its pollen germination is relatively rapid and requires < 10 % of the progamic phase. Extensive evidence discussed in this paper...
The palm tribe Chamaedoreeae displays flowers arranged in a complex partial inflorescence called an acervulus. Ortega-Chávez and Stauffer examine ontogeny in Hyophorbe lagenicaulis and show that the acervulus and the...
Oil palm (Elaeis guineensis) is an unbranched palm, possessing a single shoot apical meristem (SAM) that may remain active for more than 100 years. Through histological analysis and 3-D reconstructions, Jouannic et al...
Transplanting seagrasses can help restore ecologically important and threatened marine ecosystems. Based on the L-system formalism, Renton et al. present a functional–structural plant model of seagrass growth that...
This article provides an overview of the development and structure of spore and pollen walls in the major plant groups and summarises progress in our understanding of the molecular genetics underpinning spore/pollen...
Seeds of Pongamia pinnata used as feedstock for biodiesel production and the protein-rich residue is fed to farm animals. This paper describes seed development and early germination in terms of phenology, protein and...
