Oh, the places they’ll go! A survey of phytopathogen effectors and their host targets ($)
Blog, Plant Science Research Weekly, Research, Research BlogAll phytopathogens encode for a toolbox of secreted proteins called ‘effectors’ that promote disease formation in the best possible way. Effectors are either acting in the apoplastic space or are translocated to the host cell to target diverse processes and modulate the host using enzymatic activities.…
Arabidopsis pollen tube integrity and sperm release are regulated by RALF-mediated signaling
Blog, Plant Science Research Weekly, Research, Research BlogSuccessful fertilization in plants requires sperm cells (SCs) to be carried along the growing pollen tube (PT) until reaching the female gametophyte where the PT then bursts to release the SCs. One challenge PTs must overcome in order to achieve fertilization is deciding to rupture or not to rupture.…
Highlights of plant science 2017. Nov-Dec
Blog, Research, Research BlogThe last week of the year is the time to look back and reflect. We like to take this opportunity to recognize the good work done by the plant science community. During this final week of 2017 we've been reminding you of some of the big stories and successes that came from our community. These stories…

Stochastic gene expression in Arabidopsis thaliana
Blog, Plant Science Research Weekly, Research, Research BlogBiology is a noisy act, as the expression of the same gene in the cells of the same tissue differs. This noise can be divided into intrinsic noise, due to inherent stochasticity of molecular processes, and extrinsic noise, indicating differences between the neighboring cells. Schultheiß Araújo and…
Arabidopsis calcium-dependent protein kinase AtCPK1 plays a positive role in salt/drought-stress response ($)
Blog, Plant Science Research Weekly, Research, Research BlogCa2+-dependent protein kinases (CPKs) can transfer calcium signals via phosphorylation events, a signaling process important for plant development and response to environmental stresses. With the multitude of CPKs thus far identified and their overlapping roles in both abiotic and biotic stress response,…
APOPLASTP: prediction of effectors and plant proteins in the apoplast using machine learning ($)
Blog, Plant Science Research Weekly, Research, Research BlogThe apoplast represents a highly interactive site for intercellular communication and transport in plant-microbe interaction, that determines whether a pathogen can successfully overcome the early stages of plant defense. This site is also a battleground for an important class of apoplastic effectors…
The diversity of floral temperature patterns, and their use by pollinators
Blog, Plant Science Research Weekly, Research, Research BlogBees 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…
