- ... Symptoms of leaf and stem chlorosis and plant stunting were common in sweetpotato plants (Ipomoea batatas) in farmers' fields in two widely separated locations, Kununurra and Broome, in the tropical Kimberley region in the state of Western Australia in 2003 and 2004. In the glasshouse, progeny plants developed similar symptoms characteristic of phytoplasma infection, consisting of chlorosis and a ...

- ... Production of nitrogenous waste by livestock agriculture is a significant environmental concern in terms of pollution of land and water. In the rumens of cattle and sheep, the excessive proteolysis which contributes to inefficiency of nutrient use involves both the rumen microbial population and the intrinsic plant proteases that can mediate protein degradation in ingested fresh forage on exposure ...
