Summer pruning of apple: impacts on disease management

open access: yesAdvances in Horticultural Science, 2013
Pruning, including summer pruning, of apples can have a positive impact on disease management in two basic ways: through removal of dead tissue and inoculum, and through alteration of the canopy microclimate.

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean

open access: yesAdvanced Science, EarlyView.
This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...
