From The Scientist: Image of the day, Pseudomonas autophagy

An image from a paper published in Plant Cell is featured as The Scientists “Image of the Day” Image of the Day: Pseudomonas Autophagy Researchers identify antibacterial functions of cell death in Arabidopsis when the plant is infected with Pseudomonas. By The Scientist Staff | March 30, 2018 A plant cell (Arabidopsis) infected with Pseudomonas […]

Phytophthora palmivora establishes tissue-specific intracellular infection structures in the earliest divergent land plant lineage (OA)

Surprisingly little is known about the pathogens of liverworts. Carella et al. explored the interaction between the broad-host range pathogenic oomycete Phytophthora palmivora and the model liverwort Marchantia polymorpha. They found that the pathogen enters the host tissues and proliferates in intercellular air chambers between photosynthetic cells, and also forms intracellular hyphal structures and expresses […]

Identification and characterization of wheat stem rust resistance gene Sr21 effective against the Ug99 race group at high temperature (OA)

Stem rust is a fungal disease of wheat caused by Puccinia graminis f. sp. tritici (Pgt). The Ug99 race group of the fungus has evolved the ability to overcome most stem rust (Sr) resistance genes. Previously, Sr21, an Sr gene that confers partial resistance to Ug99, was found in diploid wheat. Chen et al. showed […]

Commentary: The discovery of nickel hyperaccumulation in the New Caledonian tree Pycnandra acuminata 40 years on: an introduction to a Virtual Issue (OA)

A Commentary by Jaffé et al. introduces a New Phytologist Virtual Issue on the curious and fascinating plants that hyperaccumulate metals. These diverse species have shed light on metal transporter proteins and mechanisms of metal tolerance, on the ecological function of metal hyperaccumulation (possibly to deter herbivores, pathogens, or neighboring plants), and might even provide […]

Rapid generation of a transgene-free powdery mildew resistant tomato by genome deletion (OA)

Using a traditional breeding approach, introducing a single gene into a desirable cultivar requires repeated backcrossing. This lengthy process can be circumvented through genetic engineering (making transgenic plants), but consumer concerns and extensive, expensive regulatory hurdles have stifled many transgenic projects. New genome editing methods are likely to have fewer regulatory obstacles, so are a […]
