Jasmonic acid and salicylic acid signaling in fern Azolla filiculoides and its cyanobiont

The phytohormones jasmonic acid (JA) and salicylic acid (SA) play key roles in how plants respond to microbes. However, this interplay between JA, SA and microbes is less understood in non-angiosperm linages. de Vries and colleagues examine JA/SA signalling between the water fern Azolla filiculoides and its nitrogen-fixing cyanobiont Nostoc azollae. They use data from […]

Ancient duons may underpin spatial patterning of gene expression in C4 leaves

C4 photosynthesis describes a biochemical CO2-concentrating mechanism that relies on the spatial separation of biochemistry between two cell types, mesophyll cells (MCs) and bundle sheath cells (BSCs). However, there is currently little evidence on how some genes are preferentially expressed in BSCs over MCs. Reyna-Llorens et al. demonstrate that two cis regulatory motifs in the […]

Ethylene signaling modulates cortical microtubule reassembly in response to salt stress

Ethylene is an important mediator during plant adaptation to salt stress. During salt stress, ethylene has been shown to promote microtubule (MT) stability and organization. Dou et al. further examine this pathway using Ag+ to block ethylene signaling in addition to using various mutants. In wildtype and ethylene overexpression mutants, adding NaCl and Ag+ hastened […]
