Choosing a favourite image is very difficult to do, not least because different images are important to us for different reasons. I have decided to focus here on an image that is not only intrinsically beautiful, but that also emphasizes the importance of looking and seeing properly when trying to understand the world around us. For me, this image, the adaxial surface of the petal of Veronica c...

A study to evaluate the fungitoxic and phytotoxic effects of extracts of V. amaygdalina, B. pinnatus, O. gratissimum and E. globules on the fungal pathogens inducing wilting on cowpea grown in Ago-Iwoye, South Western Nigeria. The extracts of all the botanicals used reduced Disease Infection Rate (DIR) in treated plants. Sclerotium rolfsii sacc induced wilting of between 4 and 12% on cowpea see...

Extracellular polysaccharide (EPS) has long been regarded as one of the most important factors involved in wilting of plants by Pseudomonas solanacearum. By means of transposon Tn5 mutagenesis, we have isolated a class of mutants that have an afluidal colony morphology but retain the ability to cause severe wilting and death of tobacco plants. One such mutant, KD700, was studied in detail. By m...

A recent study of the expression of floral organ identity genes in buttercups, poppies and their relatives has shed light on the evolutionary origin of petals.

This paper describes the relationship between protein-bound phenols in red clover, induced by different degrees of damaging before wilting and varying wilting duration, and in silo lipid metabolism. The ultimate effect of these changes on rumen biohydrogenation is the second focus of this paper. For this experiment, red clover, damaged to different degrees (not damaged (ND), crushing or frozen/...

Climate change is expected to exacerbate drought for many plants, making drought tolerance a key driver of species and ecosystem responses. Plant drought tolerance is determined by multiple traits, but the relationships among traits, either within individual plants or across species, have not been evaluated for general patterns across plant diversity. We synthesized the published data for stoma...
