Review: Exploiting induced and natural epigenetic variation for crop improvement

/
Variation provides the raw material for selection and improvement. Springer and Schmitz describe how natural and induced epigenetic variation supplements genetic variation. This review starts with a description of epigenetics, epigenomics (the genome-wide distribution of epigenetic information), and…

Speed breeding: a powerful tool to accelerate crop research and breeding

/
Watson and Ghosh et al. describe protocols to accelerate the lifecycle of several crop species using "speed breeding", which essentially involves extending the daylength to 22 hours with supplemental lighting. They describe methods and results from glasshouse and growth chamber speed breeding. In spite…

A lipid-anchored NAC transcription factor translocates into nucleus to activate GlyI gene expression involved in drought stress

/
Regulation of transcription factor (TF) localization is a common strategy for gene expression regulation. Wang et al. identified  a membrane-anchored TF, MfNACsa, as contributing to drought stress responses. In unstressed plants, MfNACsa is anchored to the plasma membrane through covalent-attachment…

Direct and indirect visualization of bacterial effector delivery into diverse plant cell types during infection

/
Bacterial effectors are proteins produced by bacteria and introduced into their hosts, where the effectors support successful infection by the pathogen. Effectors can function in diverse cells and cell compartments, but many studies of effector localization have relied on overexpression systems which…

Root tip shape governs root elongation rate under increased soil strength

/
We live at a time of unprecedented insights into root anatomy, diversity, plasticity, and the genetic underpinnings of these traits. Colombi et al. examined how wheat root tip shape contributes to soil penetration and the root’s response to increasing soil density. Not surprisingly, pointier roots…

Abscisic acid Antagonist 1 (AA1): A ray of hope for extending shelf life of leafy vegetables ($)

/
Abscisic acid (ABA) is one of the phytohormones that plays a pivotal role in a plant's life from germination to senescence, and it drew additional attention of researchers owing to its involvement in abiotic stress. Leaf senescence is a natural phenomenon but if this process can be delayed by non-toxic…

Highly cited classic papers from 2006

/
While this series highlights the latest research, a well-read scholar also needs to to know the classics. Google Scholar has a new initiative to feature highly-cited, ten-year old articles. The most-highly cited papers published in 2006 are listed by category. Plant scientists will find particular relevance…

Architecture and permeability of post-cytokinesis plasmodesmata lacking cytoplasmic sleeves ($)

/
Plasmodesmata are pores between cells through which viruses, proteins, small RNAs and other molecules can pass. The pores are usually described as being lined with a layer of plasma membrane with a tube of endoplasmic-reticulum membrane through the center. These membranes and associated proteins are…

Fatty acids in arbuscular mycorrhizal fungi are synthesized by the host plant ($)

/
In the symbiotic relationship between arbuscular mycorrhizal fungi and plants, the fungal partner greatly enhances the uptake of mineral nutrients (particularly phosphate), while in return it is supplied with organic carbon from the photosynthetic partner. Luginbuehl et al. investigated whether this…
