Seed mass, seedling size and neotropical tree seedling establishment [PDF]

Journal of Ecology, 2005
Summary We examined among‐ and within‐species effects of seed mass for seedling establishment from seed to 5 years of age in a field experiment at Paracou, French Guiana. Six seeds of each of eight species were weighed and planted into each of 120 plots (1 m2) throughout closed‐canopy forest along 12 100‐m transects in 1998.

The SlDOF9‐SlSWEET17 Module: a Switch for Controlling Sugar Distribution Between Nematode Induced Galls and Roots in Tomato

Advanced Science, EarlyView.
Root‐knot nematode (RKN) disease seriously affects the yield and quality of vegetable crops. SlDOF9‐SlSWEET17 model helps plants resist RKN infection during early stage by switching off the sugar transport capacity of other SlSWEET proteins that are hijacked by RKNs.

Cartilage‐Penetrating Framework Nucleic Acid Nanoparticles Ameliorate Osteoarthritis by Promoting Drug Delivery and Chondrocyte Uptake

Advanced Science, EarlyView.
Based on the poor cartilage penetration of tFNA, a novel tFNA‐2WL with excellent cartilage permeability and perfect chondrocyte endocytosis properties is designed and fabricated. As a result, tFNA‐2WL has a nearly seven‐fold increase in the penetration depth into the cartilage, with the same excellent cell entry properties as tFNA.
