LRX Proteins play a crucial role in pollen grain and pollen tube cell wall development

Leucine-rich repeat extensins (LRXs) are proteins involved in cell wall growth and are therefore required for plant growth processes. Fabrice et al. use pollen tube development in Arabidopsis thaliana as a vegetative plant growth model to elucidate the role of LRXs in these cellular processes. All 4 LRX genes expressed in pollen (LRX8, LRX9, LRX10, […]

The diversity of floral temperature patterns, and their use by pollinators

Bees and other pollinators experience the world in a different way to humans. They use different strategies in order to identify their surroundings, including their preferred flower species. Among these strategies, floral temperature.  These differential “floral warming” happens due to floral thermogenesis or due to captured solar radiation. Harrap et al. report in their study […]

Plant-to-plant communication triggered by systemin primes anti-herbivore resistance in tomato

Plant-to-plant communication allows plant neighbors to be warned by plant peers of stresses such as herbivory activity, sometimes by triggering priming processes. Systemin is an 18-amino acid hormone, firstly identified in tomato as a inducer of the wound response. Coppola et al. report the role of systemin application/overexpression in communication between source tomaro plants (S) […]

Review. Genomic selection in plant breeding: Methods, models, and perspectives

In future years, climate change may cause significant economic losses to countries worldwide. Consequently, genetic improvement of crops fit for drought-stressed and semi-arid regions is becoming a must. In this review, Crossa et al. assess the advances in genetic selection (GS) and genomic-enabled prediction (GP) theory in comparison with the traditional phenotypic selection; and evaluate […]

Microbial landscape of the grapevine endosphere in the context of Pierce’s disease

In vascular plants, structure and composition of microbial endosphere associations has not been studied much in the specific context of vascular diseases. This is the case of Pierce’s disease which is caused by Xylella fastidiosa and affects multiple crops and ornamental plants. This bacterium is currently regarded as a major threat in Europe, affecting very […]

A root hair-seeking endophytic microbe from an unusual volcanic swamp corn enhances phosphate uptake

In plants the location of microbes to specific cell types, including endophytes, is still scarcely described in contrast with the situation in the animal kingdom. Shehata et al. describe a bacterial endophyte (Strain 3F11, possibly Enterobacter asburiae) from Zea nicaraguensis, a wild corn growing at a Nicaraguan swamp located above rock phosphorus (P) lava flowing […]
