Flavor-cyber-agriculture: Metabolite optimization through surrogate modeling (PLOS One)
Plant Science Research WeeklyCyber-agriculture is a computer-controlled plant growing environment which regulates climatic conditions through machine learning, finding optimized variables (“recipes”) to maximize a specific plant trait. Here, Johnson et al. applied cyber-agriculture to chemotype optimization for flavor in basil…
Generating novel, dual herbicide-resistant crops using CRISPR-mediated gene editing (Plant Physiol)
Plant Science Research WeeklyThere is an ever-growing need for novel herbicides as more weeds are becoming resistant to commonly used herbicides. In a recent report from Hu et al., the authors identified that a previously described cellulose biosynthesis-inhibiting chemical, C17, possesses an herbicidal quality. The authors showed…
Review: Molecular networks of seed size control in plants ($) (Annu Rev Plant Biol)
Plant Science Research WeeklyCrop yield is largely determined by the size of seeds, and studies are being conducted to understand the complex molecular network controlling the seed size. Li et al. review the possible molecular mechanisms and regulatory networks underlying seed size control and growth, including the factors originating…
Nanomaterials enable delivery of functional genetic material without DNA integration (Nature Nanotech)
Plant Science Research WeeklyKey to success of crop improvement is the development of easier, faster and safer biomolecules-delivery systems. Here, the main limitation is the cell wall, which compromises the yield of exogenic material transfer to plant cells. In this study, Demirer et al demonstrate the advantages of infiltrated…
Crop variety management for climate adaptation supported by citizen science (PNAS)
Plant Science Research WeeklyCurrent research is focused on developing better crop varieties that could withstand the adversities posed by climate change; however, these varieties might perform worse than the locally-grown varieties in field conditions. This could be due to the release of varieties to farmers without performing…
New approaches to optimize somatic embryogenesis in maritime pine (Front Plant Sci)
Plant Science Research WeeklyPinus pinaster Aiton, commonly known as maritime pine, is a coniferous tree, native to the Mediterranean region, and presently used as a model plant when studying coniferous trees due to the interest in its environmental adaptability. Maritime pine breeding programs use somatic embryogenesis, a biotechnological…
Natural Herbicide: Cyanobacterial antimetabolite inhibits the growth of prototrophic organisms (Nature Comms)
Plant Science Research WeeklyThe shikimate pathway synthesizes aromatic amino acids in microorganisms and plants, and its absence in animals makes the shikimate pathway a common target for the development of herbicides. Brilisauer et al. 2019 isolated a novel compound from the cyanobacterium Synechococcus elongatus—7-deoxy-sedoheptulose…
Introducing curcumin biosynthesis in Arabidopsis enhances lignocellulosic biomass processing (Nature Plants)
Plant Science Research WeeklyLignin, polymerized from aromatic monolignols, provides strength to cell walls but its resistance to enzymatic degradation thwarts efforts to isolate cellulosic carbohydrates from cell walls for biofuels and other applications. It has been shown that lignin’s properties can be altered by the incorporation…
Review: Green Bioplastics as part of a circular bioeconomy ($) (TIPS)
Plant Science Research WeeklyI feel guilty about using plastics but it’s hard to break free; they are so integral to a modern lifestyle. However, the problem of plastic pollution is frightening. About 80% of manufactured plastic ends up in landfills or the natural environment. It's appalling to learn that the "Great Pacific Garbage…
