Cultivating interest in fruits

Taming fruit: How orchards have transformed the land, offered sanctuary, and inspired creativity, by Bernd Brunner, 2021. Greystone Books Ltd. One might tame lions, or dogs, or other animals, but, does one really tame fruit (or any other plants or plant parts come to that)? Yes, it is possible to domesticate – ‘taming’ by another name – plants (Jeffrey Ross-Ibarra et al., PNAS 104 (suppl 1): 8641-8648, 2007; https://doi.org/10.1073/pnas.0700643104) as it is animals. Although not necessarily carried out in the same ways, the end result – biological entities whose characteristics have to one degree or another become moulded by humanity...

The extraordinary story of an ‘ordinary’ fruit…

The Extraordinary Story of the Apple by Barrie E. Juniper and David J. Mabberley 2019. Kew Publishing. Having recently read Robert Spengler’s Fruits from the sands (and Michael Pollan’s Botany of Desire several years ago), I have some idea of the importance of the apple in the affairs of humankind. But, at best, those books could only give a hint of the cultural [in both senses of the word] and natural history of this favoured flavoursome fruit. It’s nice therefore to have before me now The Extraordinary Story of the Apple by Barrie Juniper and David Mabberley, which fleshes out...

Glycoprotein distribution in the apple pistil during the progamic phase.

Glycoprotein secretions and pollen tube kinetics in apple

The obturator bridges the downward transit of the pollen tube through style to ovary in many angiosperms. Examining pollen tube growth kinetics in the pistil in Malus × domestica and relating these to changes occurring on the obturator using histochemistry and immunocytochemistry in order to determine how the key access point of the obturator is mediated, Losada and Herrero show that glycoprotein secretion is required for a lightning pollen tube wall elongation on the surface of the obturator. This secretion is depleted following on from the passage of pollen tubes, which strongly suggests that glycoprotein secretion has a pivotal role...

Choosing the correct candidate gene (two Viewpoint papers)

Choosing the correct candidate gene (two Viewpoint papers)

This is an exciting time to study how different non-model species use common developmental genes to create such diversity in the plant world. In many cases researchers tend to identify, within newly available sequences, genes that putatively encode proteins similar to those genetically characterized in model species. A great toolbox of methods to study gene expression now exists, most of which can be outsourced: so, what is left is for researchers to choose and obtain the right samples and look at the correct genes. Samach focuses on the latter task and reminds us that it is not a trivial one, and...
