The constant struggle between plants and microbes has driven the evolution of multiple defense strategies in the host as well as offense strategies in the pathogen. To defend themselves from pathogen attack, plants often rely on elaborate signaling networks regulated by phytohormones. In turn, pathogens have adopted innovative strategies to manipulate(More)
Evolutionary success in plants is largely dependent on the successful transition from vegetative to reproductive growth. In the lifetime of a plant, flowering is not only an essential part of the reproductive process but also a critical developmental stage that can be vulnerable to environmental stresses. Exposure to stress during this period can cause(More)
The plant hormone jasmonate (JA) fulfils essential roles in plant defense and development. While most of our current understanding of the JA pathway comes from the dicotyledonous model plant Arabidopsis thaliana, new studies in monocotyledonous plants are providing additional insights into this important hormone signaling pathway. In this review, we present(More)
Pathogens and hosts are in an ongoing arms race and genes involved in host-pathogen interactions are likely to undergo diversifying selection. Fusarium plant pathogens have evolved diverse infection strategies, but how they interact with their hosts in the biotrophic infection stage remains puzzling. To address this, we analyzed the genomes of three(More)
RNA-binding proteins (RBPs) play an important role in plant host-microbe interactions. In this study, we show that the plant RBP known as FPA, which regulates 3'-end mRNA polyadenylation, negatively regulates basal resistance to bacterial pathogen Pseudomonas syringae in Arabidopsis. A custom microarray analysis reveals that flg22, a peptide derived from(More)
Plant hybrids are extensively used in agriculture to deliver increases in yields, yet the molecular basis of their superior performance (heterosis) is not well understood. Our transcriptome analysis of a number of Arabidopsis F1 hybrids identified changes to defense and stress response gene expression consistent with a reduction in basal defense levels.(More)
Some of the most devastating agricultural diseases are caused by root-infecting pathogens, yet the majority of studies on these interactions to date have focused on the host responses of aerial tissues rather than those belowground. Fusarium oxysporum is a root-infecting pathogen that causes wilt disease on several plant species including Arabidopsis(More)
Plants respond to pathogens either by investing more resources into immunity which is costly to development, or by accelerating reproductive processes such as flowering time to ensure reproduction occurs before the plant succumbs to disease. In this study we explored the link between flowering time and pathogen defense using the interaction between(More)
