Cadmium (Cd) is a toxic heavy metal that is relatively mobile in the soil and has become a serious worldwide environment problem. Cd is easily taken up by plant roots where it can be loaded into the xylem and transported to above-ground tissues. Cd accumulation in the shoot inhibits plant growth and…

Meisha Holloway-Phillips Department of Environmental Sciences, University of Basel, Switzerland m.holloway-phillips@unibas.ch The slogan, ‘more crop per drop’, which was popularised in the early 2000s, depicts the need to improve the productivity of crops for the same water inputs (Kijne…

As someone with a background in plant molecular genetics, I confess to occasionally forgetting about location. Reverse genetics is a powerful tool for picking apart gene networks, but in which organ do these genes act? Which tissue of that organ? Which cells of that tissue and which compartment of those…

Puccinia graminis f. sp. tritici (Pgt) has a strange life strategy in that it requires two hosts to complete its sexual life cycle; wheat and barberry. In the absence of barberry, it reproduces clonally; clonal reproduction limits its ability to generate diversity and therefore its ability to evade plant…

To understand gene function, it is necessary to study loss-of-function phenotypes. However, knockouts of some genes are lethal, which makes it impossible to study their loss-of-function phenotype. Although here are inducible overexpression systems and inducible knockdown systems, as yet there has been…

Optogenetics has revolutionized mammalian biology by its ability to fine-tune gene expression in individual cells by pulses of light. However, its application in plants has been challenging because the white light required for plant growth misfires the system. Ochoa-Fernandez et al. solved this problem…

The leaf epidermis is composed primarily of undulated pavement cells arranged in a jigsaw puzzle-like architecture, with neighboring cells flawlessly interlacing with one another thanks to synchronized growth, thus making it an ideal model to study morphogenesis regulation. Seeking to better understand…

Widespread genome sequencing of individuals has revealed the high level of intraspecific variability in plant species. As such, constructing high-quality pan-genomes is a growing necessity to study dynamic plant genomes. Here, Liu et al. release the soybean pan-genome formed from sequencing 2,898 accessions,…
