Publikováno v: Cornish, C, Allan, P, Gardiner, L, Nicol, P, Pardoe, H, Sherwood, C, Webster, R, Young, D & Nesbitt, M 2020, ' Between Metropole and Province: circulating botany in British museums, 1870–1940 ', Archives of Natural History, vol. 47, no. 1, pp. 124-146 . https://doi.org/10.3366/anh.2020.0627

Exchange of duplicate specimens was an important element of the relationship between metropolitan and regional museums in the period 1870–1940. Evidence of transfers of botanical museum objects such as economic botany specimens is explored for the

Increased metal tolerance and bioaccumulation of zinc and cadmium in Chlamydomonas reinhardtii expressing a AtHMA4 C-terminal domain protein

Autor: Aniefon Ibuot, Rachel E. Webster, Jon K. Pittman, Lorraine E. Williams

Publikováno v: Ibuot, A, Webster, R, Williams, L E & Pittman, J 2020, ' Increased metal tolerance and bioaccumulation of zinc and cadmium in Chlamydomonas reinhardtii expressing a AtHMA4 C-terminal domain protein ', Biotechnology and Bioengineering, vol. 117, no. 10, pp. 2996-3005 . https://doi.org/10.1002/bit.27476

The use of microalgal biomass for metal pollutant bioremediation might be improved by genetic engineering to modify the selectivity or capacity of metal biosorption. A plant cadmium (Cd) and zinc (Zn) transporter (AtHMA4) was used as a transgene to i

Knockout of multiple Arabidopsis cation/H(+) exchangers suggests isoform-specific roles in metal stress response, germination and seed mineral nutrition.

Autor: James M Connorton, Rachel E Webster, Ninghui Cheng, Jon K Pittman

Publikováno v: PLoS ONE, Vol 7, Iss 10, p e47455 (2012)

Cation/H(+) exchangers encoded by CAX genes play an important role in the vacuolar accumulation of metals including Ca(2+) and Mn(2+). Arabidopsis thaliana CAX1 and CAX3 have been previously shown to differ phylogenetically from CAX2 but the physiolo

Webster, R E, Waterworth, W M, Stuppy, W, West, C E, Ennos, R, Bray, C M & Pritchard, H W 2016, ' Biomechanical, biochemical, and morphological mechanisms of heat shock-mediated germination in Carica papaya seed ', Journal of Experimental Botany, vol. 67, no. 22, pp. 6373-6384 . https://doi.org/10.1093/jxb/erw402

Highlight Dormant Carica papaya seeds germinate rapidly after a single heat shock, following seed coat weakening that requires de novo protein synthesis but is unaffected by the germination antagonist abscisic acid.
Carica papaya (papaya) seed g

Cadmium Exposure and Phosphorus Limitation Increases Metal Content in the Freshwater Alga Chlamydomonas reinhardtii

Autor: Andrew P. Dean, Rachel E. Webster, Jon K. Pittman

Publikováno v: Environmental Science & Technology. 45:7489-7496

The characteristics of metal accumulation in freshwater microalgae are important to elucidate for a full understanding of metal cycling and toxicity in a freshwater system. This study has utilized an elemental profiling approach to investigate the im

Dynamic acclimation of photosynthesis increases plant fitness in changing environments

Autor: Kleovoulos Athanasiou, Rachel E. Webster, Beth C. Dyson, Giles N. Johnson

Publikováno v: Plant physiology. 152(1)

Plants growing in different environments develop with different photosynthetic capacities—developmental acclimation of photosynthesis. It is also possible for fully developed leaves to change their photosynthetic capacity—dynamic acclimation. The

A novel mechanism by which silica defends grasses against herbivory

Autor: Rachel E. Webster, J. W. Hunt, Giles N. Johnson, Andrew P. Dean, A.R. Ennos

Publikováno v: Annals of botany. 102(4)

BACKGROUND AND AIMS: Previous studies have shown that silica in grass leaves defends them against small herbivores, which avoid high-silica grasses and digest them less efficiently. This study tested the idea that silica can reduce digestibility by p
