Kunene is a region of harsh desert climate and Himba are exposed to climatic challenges (drought), health risks from lifestyle activities, malnutrition, and pathogen stress (Bollig, 2005; Malan, 2004).
In this work, the expression of 1,545 sugarcane SAS (mostly related to signal transduction components) was evaluated by cDNA microarrays in plants submitted to a variety of challenges: drought, phosphate starvation, herbivory by Diatraea saccharalis and endophytic bacteria inoculation (Herbaspirillum seropedicae/ Herbaspirillum rubrisubalbicans and Gluconacetobacter diazotrophicus).
Like many other crop species, sustainability of its production is severely challenged by drought, depressing up to 40% of the yield annually.
Fig. 5 Amount of soluble hydrogen peroxide per gram of leaf tissue from oilseed rape treated with nutrient solution containing IONs and challenged with drought for 5 days (n = 16, p value = 0.004).
Thereafter, plants were challenged with drought by withholding water for 10 days.
The Southeastern drought almost challenges the longstanding Western drought, centered in California, as the largest in the nation.
Rapid urbanization and climate variability impacts increase with more extreme precipitation and drought events, challenging stormwater management in terms of both flood control and water quality.
A total of 10 cDNA libraries including 8 from drought challenged tissues and 2 from salinity challenged tissues were generated.
Chickpea (Cicer arietinum L ., an important grain legume crop of the world is seriously challenged by terminal drought and salinity stresses.
In summary, the present study provides 20,162 new chickpea ESTs (6,404 unigenes) including 11,904 ESTs (4,558 unigenes) from drought challenged libraries and 8,258 ESTs (2,595 unigenes) from salinity challenged libraries.
