Evidence that tolerance of Eutrema salsugineum to low phosphate conditions is hard-wired by constitutive metabolic and root-associated adaptations.

Planta 2019 Nov 28;251(1):18. Epub 2019 Nov 28.

Department of Biology, McMaster University, Hamilton, ON, L8S 4K1, Canada.

Main Conclusion: The extremophyte Eutrema salsugineum (Yukon ecotype) has adapted to an environment low in available phosphate through metabolic and root-associated traits that enables it to efficiently retrieve, use, and recycle phosphorus. Efficient phosphate (Pi) use by plants would increase crop productivity under Pi-limiting conditions and reduce our reliance on Pi applied as fertilizer. An ecotype of Eutrema salsugineum originating from the Yukon, Canada, shows no evidence of decreased relative growth rate or biomass under low Pi conditions and, as such, offers a promising model for identifying mechanisms to improve Pi use by crops.

Epimutations are associated with CHROMOMETHYLASE 3-induced de novo DNA methylation.

Elife 2019 07 29;8. Epub 2019 Jul 29.

Department of Genetics, University of Georgia, Athens, United States.

In many plant species, a subset of transcribed genes are characterized by strictly CG-context DNA methylation, referred to as gene body methylation (gbM). The mechanisms that establish gbM are unclear, yet flowering plant species naturally without gbM lack the DNA methyltransferase, CMT3, which maintains CHG (H = A, C, or T) and not CG methylation at constitutive heterochromatin. Here, we identify the mechanistic basis for gbM establishment by expressing in a species naturally lacking expression reconstituted gbM through a progression of de novo CHG methylation on expressed genes, followed by the accumulation of CG methylation that could be inherited even following loss of the transgene.

Loss of Gene Body Methylation in Eutrema salsugineum Is Associated with Reduced Gene Expression.

Mol Biol Evol 2019 01;36(1):155-158

Department of Ecology and Evolutionary Biology, University of California Irvine, Irvine, CA.

Gene body methylation (gbM) is typically characterized by DNA methylation in the CG context within coding regions and is associated with constitutive genes that have moderate to high expression levels. A recent study discovered the loss of gbM in two plant species (Eutrema salsugineum and Conringia planisiliqua), illustrating that gbM is not necessary for survival and reproduction. The same paper stated there was no detectable effect of gbM loss on gene expression (GE). Read More

Halophytism: What Have We Learnt From Relative Model Systems?

Plant Physiol 2018 11 20;178(3):972-988. Epub 2018 Sep 20.

French Associates' Institute for Agriculture and Biotechnology of Drylands, Jacob Blaustein Institutes for Desert Research, Ben-Gurion University of the Negev, Midreshet Ben-Gurion 8499000, Israel

Halophytes are able to thrive in salt concentrations that would kill 99% of other plant species, and identifying their salt-adaptive mechanisms has great potential for improving the tolerance of crop plants to salinized soils. Much research has focused on the physiological basis of halophyte salt tolerance, whereas the elucidation of molecular mechanisms has traditionally lagged behind due to the absence of a model halophyte system. However, over the last decade and a half, two Arabidopsis () relatives, and , have been established as transformation-competent models with various genetic resources including high-quality genome assemblies.

Plastid terminal oxidase requires translocation to the grana stacks to act as a sink for electron transport.

Proc Natl Acad Sci U S A 2018 09 4;115(38):9634-9639. Epub 2018 Sep 4.

School of Earth and Environmental Sciences, University of Manchester, M13 9PT Manchester, United Kingdom

The plastid terminal oxidase (PTOX) has been shown to be an important sink for photosynthetic electron transport in stress-tolerant plants. However, overexpression studies in stress-sensitive species have previously failed to induce significant activity of this protein. Here we show that overexpression of PTOX from the salt-tolerant brassica species does not, alone, result in activity, but that overexpressing plants show faster induction and a greater final level of PTOX activity once exposed to salt stress.
