Whenever we talk about global trends there are of course local variations. Here, Piao et al. discuss recent trends of global greening, which is occurring at arctic as well as temperate and tropical regions. Overall, this greening is attributed to increasing atmospheric CO2, which promotes plant growth,…

Auxins participate in nearly every aspect of plants' life cycle, but the information about the actual distribution of this hormone is scarce. The location of the hormone has been inferred using reporters based on auxin-transcriptional responses or auxin-dependent degradation signals. For a direct visualization,…

Iron (Fe) is an important micronutrient needed by plants for survival. Plants have evolved a range of morphological, physiological and molecular responses to Fe availability, including the transcriptional regulation of over one thousand genes in response to Fe deficiency (-Fe) in Arabidopsis. However,…

Storage proteins secreted into vacuoles during seed development serve as precursors for germination and plant growth. In this paper, Ren et al. identified a regulator, GLUTELIN PRECURSOR ACCUMULATION 5 (GPA5) that is involved in protein trafficking into the vacuoles during seed development. The loss…

While cell division and cell expansion are known to be determinants of plant organ growth, little is known about the role of cell elimination and death in this process. Cell death indicators such as cell death- and autolysis-associated cysteine proteases have been observed in cells overlying the site…

Water and nutrient availability are a major limiting factors for plant productivity. Plant have evolved a series of complex adaptive features that help them to survive in the hostile environment. Upregulation of lignin biosynthetic genes in roots under salt and water stress have been reported in some…

Yellow rust is a fungal disease of wheat. Three mutants with enhanced resistance were identified in wild emmer wheat from different locations were previously mapped to the same region of chromosome 1B. Given that each locus showed a different degree of resistance, it was presumed that they were non-allelic.…

FLS2 is a well-characterized cell-surface receptor that recognizes a short epitope found on most bacterial flagellin proteins. The plant pathogen Agrobacterium tumefaciens, causative agent of crown gall disease, deviates strongly at this epitope region, and so is generally not recognized by FLS2 receptors,…
