Fungal transplants from close relatives help endangered plants fight off disease
Endophytic fungi, which reside inside leaves, often protect plants from pathogens. In a paper recently published in Phytobiomes Journal, Chock along with fellow University of Hawaii researchers Benjamin Hoyt and Anthony Amend, treated E. koolauensis plants with endophytic fungi isolated from the leaves of closely related plant species, then assessed the resistance of these inoculated plants against myrtle rust. Although some individual strains of fungi seemed to decrease the pathogen severity, plants were most protected against the pathogen when treated with a complex mixture of microbes prepared from homogenized leaves of these related plants.

Stronger lettuce stems are a key part of disease resistance
Lettuce drop is a lettuce disease that results in browning or wilting of leaves, plant collapse, and death. The disease has not been well-researched, but a new study shows that a stronger stem increases resistance to lettuce drop.

Hidden mechanisms of apple watercore formation
Watercore apples with enhanced sweet flavors are preferred in most Asian countries, although the underlying mechanisms of the transparent water-soaked symptom formation remained unknown. A collaborative research team conducted site-specific cellular analyses in conjunction with two principally different osmometers to reveal the cellular mechanisms related to the tissue appearance. This research team consists of members from Ehime University, the National Agriculture and Food Research Organization, Japan, and the University of Buenos Aires, Argentina.

Identification of plant-parasitic nematode attractant
A research collaboration based in Kumamoto University, Japan has become the first to successfully purify and identify an attractant for crop-infecting root-knot nematodes from flaxseeds. Their experiments revealed that rhamnogalacturonan-I (RG-I), a flaxseed cell wall component, can attract root-knot nematodes. The linkages between rhamnose and L-galactose are essential for the attraction.

Tailored approach to fertilizer use can achieve triple-wins for smallholder farmers
A meta-analysis study assessed the performance of site-specific nutrient management (SSNM) applied to smallholder cereal cropping systems in Asia and Africa; the evidence points to triple-wins but weak extension and unfavorable policies hamper adoption

New imaging, machine-learning methods speed effort to reduce crops’ need for water
Scientists have developed and deployed a series of new imaging and machine-learning tools to discover attributes that contribute to water-use efficiency in crop plants during photosynthesis and to reveal the genetic basis of variation in those traits.

Humble pond plant duckweed may help researchers to develop better crops
Duckweed, a tiny freshwater floating plant, is an excellent laboratory model for scientists to discover new strategies for growing hardier and more sustainable crops in an age of climate change and global population boom, a Rutgers-led study finds.

How plants compensate symbiotic microbes
Combining economics, psychology and studies of fertilizer application, researchers find that plants nearly follow an ''equal pay for equal work'' rule when giving resources to partner microbes - except when those microbes underperform.

Study: constructed wetlands are best protection for agricultural runoff into waterways
Amy Hansen of the University of Kansas and her co-authors found constructed wetlands are the most effective means to improve water quality, especially if the size and location are evaluated at the scale of a watershed -- an entire region that drains into a common waterway.

Drone tech's next big target: insect pest management
Drones keep getting smaller, while their potential applications keep getting bigger. And now unmanned aircraft systems are taking on some of the world's biggest small problems: insect pests. From crop-munching caterpillars to disease-transmitting mosquitoes, insects that threaten crops, ecosystems, and public health are being targeted with new pest-management strategies that deploy drones for detection and control. A variety of these applications are featured in a new special collection in the Journal of Economic Entomology.
