Introduction Conclusions References

A study by Wan et al. in this issue of Cell demonstrates that the majority of oncogenic mutations in the B-Raf protein kinase result in increased catalytic activity, through disruption of the autoinhibited state of the kinase domain. Surprisingly, several mutations lead to impaired B-Raf kinase activity, yet these mutants are nevertheless capable of stimulating downstream signaling through tran...

In this study we use a high-quality data set of in situ ozone measurements at a suburban site called Mohali in the state of Punjab to estimate ozone-related crop yield losses for wheat, rice, cotton and maize for Punjab and the neighbouring state Haryana for the years 2011–2013. We intercompare crop yield loss estimates according to different exposure metrics, such as AOT40 (accumulated ozone e...

A field experiment was conducted during 2006-07 and 2007-08 at Ludhiana to study the effect of different agronomic practices on growth, grain yield, malt yield and losses of malt barley (Hordeum vulgare L.).The study revealed that plant height, dry matter accumulation, grain and straw yield were statistically at par with different method of sowing during both the years. Similar trend was also o...
