We demonstrate that ANJ1, a higher plant homolog of the bacterial molecular chaperone DnaJ, is a substrate in vitro for protein farnesyl- and geranylgeranyl-transferase activities present in cell extracts of the plant Atriplex nummularia and yeast Saccharomyces cerevisiae. Isoprenylation did not occur when cysteine was replaced by serine in the CAQQ motif at the carboxyl terminus of ANJ1, indic...

Atriplex nummularia (Lindl.) es un arbusto utilizado como recurso forrajero estratégico en sistemas ganaderos de zonas áridas y semiáridas época estival. El 2019 se crearon dos módulos seguimiento esta especie el sur Chile; las localidades Los Sauces (secano interior, 37° latitud sur) Carillanca (valle central seco, 38° sur). Se evaluó crecimiento durante 3 años (2019-2021) calidad forrajera de...

As the worldwide population continues to rise, so does global demand for agricultural production. This scenario of uncertain food supply is exacerbated by high salinization soils worldwide, a serious constraint crop productivity. In this context, there an increasing need alternative sustainable crops. Halophytes are thought be promising source due their natural ability grow in saline and multip...

The concentration of salts in the vesiculated hairs of Atriplex halimus L. was measured and was remarkably higher than that of the leaf sap and xylem exudate. In spite of their unusually high salt content, these hairs when immersed seemed unable to absorb water, in apparent contradiction to the previously held hypothesis that vesiculated hairs make it possible for such plants to absorb water fr...

Photoluminescence spectroscopic probes offer the potential for differentiation among plant species in real-time. Spectral emission signatures (excitation at 365 nm) from three different pH (2.2, 7.5 and 12.5) phosphate buffered saline (PBS) extracts from two grasses, Sporobolus flexuosus (Thurb. ex Vasey) Rydb., [mesa dropseed], and Pleuraphis mutica Buckley [tobosa], two forbs, Dimorphocarpa w...

This paper reviews historical, philosophical and socio-cultural information as a means of explaining why saltbush in Australia has declined. That decline coincided with introduced hard hoofed animals overgrazing native pastures and was compounded by land clearing. Over time, losing ecosystem diversity degraded vegetation, soil and water resources; subsequently, watertables rose. A benefit of sa...
