Rhizosphere ecology of lumichrome and riboflavin, two bacterial signal molecules eliciting developmental changes in plants
Lumichrome and riboflavin are novel molecules from rhizobial exudates that stimulate plant growth. Reported studies have revealed major developmental changes elicited by lumichrome at very low nanomolar concentrations (5 nM) in plants, which include early initiation of trifoliate leaves, expansion of unifoliate and trifoliate leaves, increased stem elongation and leaf area, and consequently gre...

Short-day treatment alters Douglas-fir seedling dehardening and transplant root proliferation at varying rhizosphere temperatures
We tested effects of shortened day length during nursery culture on Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) seedling development at dormancy release. Seedlings from a 428N source were grown either under ambient photoperiods (long-day (LD)) or with a 28 day period of 9 h light : 15 h dark photoperiods (short-day (SD)). Seedlings were periodically removed from freezer st...
متن کاملPriority regions for research on dryland cereals and legumes
Dryland cereals and legumes are important crops in farming systems across the world. Yet they are frequently neglected among the priorities for international agricultural research and development, often due to lack of information on their magnitude and extent. Given what we know about the global distribution of dryland cereals and legumes, what regions should be high priority for research and...
متن کاملEssential amino-acids of some common tropical legumes and cereals.
In spite of numerous amino-acid analyses of foodstuffs recorded in recent years, there is little reliable information about the amounts of essential amino-acids in the legumes commonly consumed in tropical countries. Early studies (Jones, 1938) were directed to the preparation of the aand ,%globulins present in some legumes and to the determination of their lysine, tryptophan and cystine conten...
