The fungal pathogen Fusarium virguliforme invades a wide spectrum of host plants, ranging from eudicots to monocots. Interestingly, fungal root colonization results in disease-producing phenotypes only in certain eudicot hosts (Kolander et al., 2012). For instance, F. virguliforme causes sudden death…

Plants have veins too. As in animals, the plant vasculature facilitates the circulation of water and nutrients across tissues and organs. Unlike animals, it originates from a self-renewing population of meristematic cells forming the (pro)cambium ring within stems and tree trunks and roots. Local signals…

Baetsen-Young  et al. identified key transcriptomic differences in coexpression networks following Fusarium virguliforme infection of symptomatic (soybean) vs. asymptomatic (corn) hosts    Plant Cell https://doi.org/10.1105/tpc.19.00697 By Amy Baetsen-Young and Brad Day, Michigan State University Background:…

Huang  et al. found that SA inhibits hook formation and is dependent on the ET pathway in Arabidopsis. Plant Cell https://doi.org/10.1105/tpc. 19.00658 By Peixin Huang, Yichuan Wang, and Hongwei Guo Background: For germnating seedlings to survive and become a mature plant, they must push through…

In addition to promoting plant growth and development, the colonization of roots by beneficial microorganisms often provides aboveground tissues with enhanced resistance to pathogen attack. This form of resistance, referred to as ‘induced systemic resistance’ (ISR), relies on the long-distance movement…

O’Leary et al. show that the TOR signalling pathway in plants responds to amino acid levels by eliciting regulatory effects on respiratory energy metabolism at night, uniting a hallmark mechanism of TOR regulation across eukaryotes.

Aung et al. reveal that pathogenic bacteria target plant plasmodesmata to colonize and invade surrounding tissues. Plant Cell https://doi.org/10.1105/tpc.19.00707 By Kyaw Aung and Sheng Yang He   Background: Multicellular organisms like animals and plants host a multitude of microorganisms.…
