Reading this review by Diaz et al. feels a bit like reading a bad report card. Although we know we’re failing in our role as Earth’s stewards, we don’t always want to be reminded of this. But, in this case we need to read and act on the suggestions for improvement. The authors review the findings…

COP9 signalosome (CSN) is a conserved multi-subunit complex in higher eukaryotes that was originally identified as a regulator of plant photomorphogenesis. It functions by regulating ubiquitin-mediated protein stability, through the deneddylase enzymatic acitivity of the CSN5 subunit. CSN5 is encoded…

With global temperatures rising, tolerance to heat is becoming increasingly important as a breeding target for crop plants, but it is a highly complex response that includes processes including plant cooling capacity, growth recovery, and maintenance of photosynthesis. Using Arabidopsis, Gao et al. developed…

Although the first signaling peptide identified in plants, systemin, is involved in stress responses, developmentally important peptide signals have largely occupied the limelight. This Tansley Review by Chen et al. summarizes recent insights into peptides with a role in stress responses: wounding, pathogen…

Simply put, as food demand increases due to population growth and increased affluence, crop yields are likely to decrease due to the changing climate. Plant scientists will be familiar with many research avenues that aim to address this disconnect, ranging from increasing crop resilience to abiotic stresses,…

Bulliform cells lie in rows along the upper (adaxial) surface of the maize leaf, and through changes in volume contribute to leaf-rolling, which is a response to water deficit. Several mutants have been identified that affect bulliform cell formation and function, but as yet their occurance in natural…

Auxin plays a major role in plant development and can alter the developmental program following the stress response. In this paper, Yamauchi et al., have identified the auxin signaling cascade involved in the development of aerenchyma and regulators of this auxin signaling might also be involved in lateral…

Glucosinolates are secondary metabolites synthesized by plants as a defense compound against pathogen and herbivore. In this paper Salehin et al., have demonstrated regulation of aliphatic glucosinolate levels by auxin signaling that promotes drought tolerance in Arabidopsis. The Aux/IAA proteins are…
