How Plants Keep Troublemakers Out and Water In

Kaundal et al. examine how a protein keeps plants safe from invading pathogens and dehydration http://www.plantcell.org/content/29/9/2233 By Amita Kaundal, Vemanna S. Ramu, Kirankumar S. Mysore Background: To cause disease in plants, bacteria must enter plant tissue and multiply. Bacteria and…

Review: Outer, inner and planar polarity in the Arabidopsis root

Despite vast differences across all living organisms, most eukaryotes display some form of cellular polarity which enables them to carry out specialized functions. The coordination of cell polarity within a single tissue layer is known as planar polarity. Nakamura and Grebe highlight the unique execution…

Review: The responses of root system architecture to nutrients

The arrangement of a plant’s root system in the soil (root system architecture, RSA) changes in response to nutrients through different signaling pathways. It is assumed that RSA adapts to optimize the uptake of nutrients from the environment, but strong evidence is still lacking. This review by Shahzad…

PLETHORA transcription factors orchestrate de novo organ patterning during Arabidopsis lateral root outgrowth

Lateral root development in plants is a complex process that involves co-ordination of several molecular components to initiate the formation of meristematic cells. Uncovering the details of these processes is confounded by functional redundancy and tight cyclic regulation of different components in…

Light sheet microscopy imaging of light absorption and photosynthesis distribution in plant tissue

Chlorophyll fluorescence is a common tool to investigate the behavior of the photosynthetic appratus, therefore photosynthetic capacity, at any physiological state. However, the different optical density of the samples can lead to light-dependent over- or underestimation of effective PSII quantum yields.…

Re-creation of a key step in the evolutionary switch from C3 to C4 leaf anatomy

The C4 Rice project aims to transition rice from a C3 crop to one that performs C4 photosynthesis, in order to realize a predicted 50% increase in yield.  Here, Wang et al. expressed a positive regulator of chloroplast development, the maize GOLDEN2-LIKE transcription factor, in rice.  The resulting…

Chlamydomonas photoreceptor gene editing by zinc-finger nucleases and CRISPR/Cas9

New genome editing technology, such as zinc-finger nucleases and CRISPR/Cas9, are revolutionizing reverse genetics studies because they allow fast and precise genetic modifications in many species. However, they require efficient transformation and selection methods. This is notably a problem for algae…
