Researchers found that garlic mustard targets arbuscular mycorrhizal fungi, harming native plants and disrupting their growth. The invasive plant's phytochemical poisons disrupt native plants' mycorrhizal associations, stunting their growth.
A study by Texas A&M AgriLife Communications reveals that planting containerized seedlings in the fall can significantly increase the survival rate of pine tree seedlings, with a 93% survival rate compared to 67%. The shift in reforestation methods may help landowners improve their forest land management and reduce waste.
The study reveals that a gene called phytochrome-interacting factor 1 (PIF1) regulates the production of protochlorophyll, a precursor to chlorophyll. Plants with mutated PIF1 genes accumulate too much protochlorophyll, leading to photo-oxidative stress and bleaching on leaves.
Researchers have discovered a two-member family of protein molecules, phototropin, that detects blue photons and guides seedling growth towards light. This finding has profound influences on seedling development and is being intensely studied by chemists and biophysicists.
Biologists at Rice University are investigating the genetic and environmental factors behind Chinese tallow trees' success in Texas. The research aims to understand how the trees' low defenses against insects contribute to their rapid growth and success as an invasive species.
A Texas Agricultural Experiment Station study found that early planting, even in September, can give slash pine trees a growing head start towards better survivability. Container-grown trees showed more than 90% survival after the first year, compared to 60% for bare-root trees.
UC researchers have confirmed that coast redwood and Douglas fir are susceptible to Phytophthora ramorum, the pathogen causing Sudden Oak Death. The disease has already killed tens of thousands of oaks and tanoaks along California's northern coast.
Research in tropical dry forests reveals that fragmentation decreases seedling quality, with reduced germination rates and smaller leaves. Despite the negative effects, isolated trees can still serve as genetic stepping stones for pollinating moths and gene flow between populations.
Researchers found that a soil pathogen in temperate forests kills most black cherry seedlings within a few meters of their parent tree. This allows other species to take root and increase forest diversity. The study suggests microbial pathogens play a crucial role in shaping forest communities.
A new study by botanists at the University of Georgia shows that trees left standing in pastures can dominate reproduction in nearby remnant forests, creating a genetic bottleneck. The research indicates that tropical forest survival may be more complex than known, requiring new conservation strategies.
