Transgenic salt tolerance
Over 6% of the worlds total land area is naturally salt-affected and even more is becoming so as a consequence of mismanaged agricultural practices like land clearing, improper irrigation etc. Salt stress affects plants not only by causing water shortage but also through toxicity of Na+ and Cl- ions as well as shortage of K+, Ca2+ and NO3. In a transgenic line of canola (Brassica napus), Liang-ju Wang and co-workers from Nanjing Agricultural University in China seems to have solved at least some of the problems. They used a light-induced Yhem1 gene encoding aminolevulinate synthase which is crucial for biosynthesis of 5-aminolevulinate (5-ALA). This compound has previously been shown to confer increased salt tolerance. Transgenic Yhem1-canola yielded more than three times more seeds than wildtype plants when grown under high-salt conditions and also accumulated more shoot and root biomass. Short-term experiments revealed that this was probably due to higher expression of the gene encoding Rubisco small subunit as well as increased diurnal photosynthetic rates in transgenic plants. Cl- levels in leaves was significantly reduced in the transgenic plants and so was K+ and several other ions, while Fe accumulation was improved.
