Some of us have been blessed with a green thumb while others have difficulty with their plants lasting the week.\u00a0 To be fair to so-called “black-thumbed” readers, it’s not exactly easy to tell what the cause of a plant’s ailment is; for crying out loud, who knew cacti could get sunburns?\u00a0\u00a0<\/span><\/p>\n

Fortunately, a publication in April 2020 from MIT may be the answer to all plant parents’ prayers.\u00a0 A team of engineers has developed a way to track how plants respond to a variety of everyday stresses.<\/span><\/p>\n

According to the head of the study, Michael S. Strano, plants use bursts of the chemical hydrogen peroxide to signal that it <\/span>has been injured.\u00a0 The distress beacon stimulates nearby leaf cells that then produce the necessary materials to aid in the healing process.\u00a0 This can be seen when you pluck off a leaf: within the span of a few days, a callous has formed to protect the plant from potential infection.<\/p>\n

Understanding plants\u2019 response to stress can act as a preventative measure to crop failure.<\/span><\/p><\/blockquote>\n

Strano’s lab has been able to monitor these stress releases via carbon-based nanotubes, extremely small sensors that are embedded in the sample plant’s leaves.\u00a0 The waves of hydrogen peroxide are detected by the nanotubes, and through graphical analysis, the engineers are able to distinguish between different types of stress and different species of plants.\u00a0 <\/span><\/p>\n

They hypothesize that each plant responds differently to stress because every plant has different mechanisms to counteract the damage.\u00a0 For example, while a cactus is able to be burned by the sun, it has a much higher capability of dealing with sunburn as opposed to<\/span> being cut in half.\u00a0 This particular study utilized strawberries, arugula, spinach, and other common crops (all of which produced different signals),\u00a0 but in theory, the nanocarbon tube sensors should be applicable to any type of plant.<\/span><\/p>\n

This leads the research team to believe their work could be beneficial to the field of agriculture.\u00a0 By being able to identify what stressors impact plant growth the most, farmers can adjust their fields and greenhouses to better accommodate their crops.\u00a0 This, in turn, will produce a higher yield of food.<\/span><\/p>\n

As of right now, Strano’s lab is able to accurately analyze plants’ stress in response to physical injury, infection, heat, and light damage.\u00a0 In the future, they hope to use this information and method to determine why some plants are immune to certain pathogens and others are not.<\/span><\/p>\n
