Scientists share keys to drought tolerance Some of the world's leading crop researchers met in Adelaide recently to discuss breeding strategies for increasing plants' water-use efficiency By Gio Braidotti With global grain stocks at their lowest levels in decades and water stress accounting for a glaring proportion of global shortfalls, the 2007 Genomics Symposium in Adelaide allowed some of the world's best drought-tolerance pre-breeders to put their heads together on new ways to test, select and dissect traits that can maintain yields under drought... Overall, genomics is currently playing a more peripheral role in the work of conventional pre-breeders, with scientists attempting to dissect the genetic basis of drought tolerance and map traits to discrete chromosomal subregions (called QTLs or quantitative trait loci)... The number of GM field-trials is on the rise...

Homology to known stress-responsive genes and the results presented show that the transcription factors identified in this project are involved in plant salt stress responses... Further experiments should be performed to determine the role of these transcription factors in plant responses to salt stress... In the project, the aim was to identify transcription factors that are important in regulating genes involved in salinity tolerance...

Soil salinity refers to a high concentration of salts in the landscape, mainly common salt or sodium chloride (NaCl), which has a negative impact on soil and water quality... A related protein in the test plant Arabidopsis, AtNHX1, has a very well-characterised role in salt tolerance... A deeper understanding of the mechanisms underlying this salt tolerance will be critical to the use of NHX proteins in producing transgenic salt-tolerant crop species...

While the role of AtNHX5 and AtNHX6 in salt tolerance is not so clear, recent work in the Gendall laboratory at La Trobe University has indicated that AtNHX5 and AtNHX6 may be involved in salt tolerance of plant cells... As part of the investigation, I have discovered that the nhx5 nhx6 double mutant has a defect in the accumulation of normal storage proteins in seeds... Future work on the project will include an analysis of the storage protein content of seeds in which AtNHX5 or AtNHX6 are over-expressed, as well as an investigation of the stability of these storage proteins over time...
