Plants on aspirin

When pathogens enter a plant, infected cells set off an alarm before they die. They discharge methylsalicylic acid, which is later transformed into salicylic acid, triggering an immune response. Hence, salicylic acid is a ...

The balancing act between plant growth and defense

Researchers from Kumamoto University in Japan have pinpointed the mechanism that regulates the balance between plant growth and defense. Plants synthesize and accumulate protective hormones to protect them from pathogen infections, ...

How plants synthesise salicylic acid

The pain-relieving effect of salicylic acid, now sold as Aspirin, has been known for thousands of years. Besides being a useful drug with numerous health applications, it is a stress hormone made by plants which is essential ...

Polymers join forces to deliver

An affordable, heavy metal- and odor-free method for making hollow polymer nanostructures has been designed by A*STAR researchers. These structures could find use as delivery systems for personal care products, drugs and ...

Chelated calcium benefits poinsettias

Vegetatively propagated unrooted cuttings of annual ornamentals are typically grown in equatorial locations and shipped via airfreight to propagators located in temperate climates. Cutting quality, defined as the resistance ...

Linking sensing to signaling during plant immunity

Plant defense against invading pathogens relies upon effective recognition of non-self organisms and a subsequent signaling response characterized by reprogramming of host gene expression and localized cell death to combat ...
