1. Energy values of some feedstuffs, determined with broilers and for prediction equations. / Valores energÃticos de alguns alimentos, determinados com frangos de corte e por equaÃÃes de prediÃÃo
Dois ensaios metabÃlicos com pintos em crescimento (mÃtodo tradicional de coleta total de excretas) foram conduzidos no Departamento de Zootecnia da UFLA, Lavras â MG, para determinar a Energia MetabolizÃvel Aparente corrigida (EMAn) de alguns alimentos, bem como a determinaÃÃo dessa energia por equaÃÃes de prediÃÃo descritas na literatura nacional

2. Nitrogen fixation (acetylene reduction) associated with roots of winter wheat and sorghum in Nebraska.
Root segments and root-soil cores (6.5-cm diameter) from fields and nurseries of winter wheat and sorghum were tested for N2 fixation by using the acetylene reduction assay. Wheat samples (approximately 1,200) from 109 sites generally had low or no activity (0 to 3.1 nmol of C2H4 produced per h per g [dry weight] of root segments), even after 24 h of incubat

3. Effect of substrate on metabolite production of Alternaria alternata.
Alternariol and alternariol monomethyl ether are commonly associated with weathered grain sorghum. Production of these metabolites and altenuene by isolates of Alternaria alternata was evaluated on various sterile grain substrates. At 35% moisture content and 25 C, metabolite yields were highest on rice, intermediate on sorghums, and lowest on wheat and yell

4. Modulation of proline-rich protein biosynthesis in rat parotid glands by sorghums with high tannin levels.
Feeding of sorghum with a high level of tannin (high-tannin sorghum) to rats caused changes in gene expression in parotid glands similar to isoproterenol treatment. Within 3 days the parotid glands were enlarged about 3-fold and a series of proline-rich proteins were increased about 12-fold. Unlike isoproterenol treatment, no changes were observed in the sub

5. The weediness of wild plants: molecular analysis of genes influencing dispersal and persistence of johnsongrass, Sorghum halepense (L.) Pers.
Many major weeds rely upon vegetative dispersal by rhizomes and seed dispersal by "shattering" of the mature inflorescence. We report molecular analysis of these traits in a cross between cultivated and wild species of Sorghum that are the probable progenitors of the major weed "johnsongrass." By restriction fragment length polymorphism mapping, variation in

6. Comparative Analysis of Qtls Affecting Plant Height and Maturity across the Poaceae, in Reference to an Interspecific Sorghum Population
Correspondence among QTLs affecting height and/or flowering was investigated across the five races of sorghum, an interspecific sorghum F(2) population, and 32 previously published sorghum, maize, rice, wheat, and barley populations revealing 185 QTLs or discrete mutants. Among nine QTLs mapped in the interspecific sorghum population (six affecting height an
