Embryonic photosynthesis affects post-germination plant growth

Sela, Ayala ; Piskurewicz, Urszula ; Megies, Christian ; Mène-Saffrané, Laurent ; Finazzi, Giovanni ; Lopez-Molina, Luis

In: Plant Physiology, 2020, vol. 182, no. 4, p. 2166–2181

Photosynthesis is the fundamental process fueling plant vegetative growth and development. The progeny of plants relies on maternal photosynthesis, via food reserves in the seed, to supply the necessary energy for seed germination and early seedling establishment. Intriguingly, before seed maturation, Arabidopsis (Arabidopsis thaliana) embryos are also photosynthetically active, the...

A substrate of the ABC transporter PEN3 stimulates bacterial flagellin (flg22)-induced callose deposition in Arabidopsis thaliana

Matern, Andreas ; Böttcher, Christoph ; Eschen-Lippold, Lennart ; Westermann, Bernhard ; Smolka, Ulrike ; Döll, Stefanie ; Trempel, Fabian ; Aryal, Bibek ; Scheel, Dierk ; Geisler, Markus ; Rosahl, Sabine

Nonhost resistance of Arabidopsis thaliana against Phytophthora infestans, a filamentous eukaryotic microbe and the causal agent of potato late blight, is based on a multilayered defense system. Arabidopsis thaliana controls pathogen entry through the penetration-resistance genes PEN2 and PEN3, encoding an atypical myrosinase and an ABC transporter, respectively, required for synthesis and...

Removal of a subset of non-essential genes fully attenuates a highly virulent mycoplasma strain

Jores, Joerg ; Ma, Li ; Ssajjakambwe, Paul ; Schieck, Elise ; Liljander, Anne ; Chandran, Suchismita ; Stoffel, Michael H. ; Cippa, Valentina ; Arfi, Yonathan ; Assad-Garcia, Nacyra ; Falquet, Laurent ; Sirand-Pugnet, Pascal ; Blanchard, Alain ; Lartigue, Carole ; Posthaus, Horst ; Labroussaa, Fabien ; Vashee, Sanjay

Mycoplasmas are the smallest free-living organisms and cause a number of economically important diseases affecting humans, animals, insects, and plants. Here, we demonstrate that highly virulent Mycoplasma mycoides subspecies capri (Mmc) can be fully attenuated via targeted deletion of non-essential genes encoding, among others, potential virulence traits. Five genomic regions, representing...
