We still don't know what many #RNA helicases do in #plants, but today Yang et al. get us one step closer with their study of the #maize DEAD-box RNA helicase ZmRH48.

Tar spot is a devastating #disease of #maize (#corn) caused by the obligate #fungus Phyllachora maydis which was first identified in North America in 2015 - article on elucidating its genome and obligate nature in the journal Molecular Plant-Microbe Interactions (2023, vol. 36, issue 7, pp. 411-424) by Joshua S. MacCready and others - https://doi.org/10.1094/MPMI-10-22-0213-R

The polyphagous fall armyworm is a significant #pest in its native range, the Americas. It has spread to Africa and Asia and has become a devastating pest of #maize and other crops like sorghum or cotton. A new #pheromone component has been described which significantly improves trapping of male moths - article in Pest Management Science (2023, vol. 79, issue 7, pp. 2831-2839) by Ahmed M. Saveer and others - https://doi.org/10.1002/ps.7460

Goss's bacterial #wilt and leaf blight of #maize caused by Clavibacter nebraskensis has been reported from North America since 1969 and has caused serious outbreaks in the 1970s and recently resurged in the U.S. #corn belt. It is of quarantine concern in other regions. Review in Molecular Plant Pathology (2023, vol. 24, issue 7, pp. 675-692) by Ebrahim Osdaghi and others - https://doi.org/10.1111/mpp.13268

‘Corn smut’ is a fungus that grows on maize. The name comes from the fact that indigenous Mexicans thought it looked vaguely pornographic.

In an unexpected twist, Zhang et al. reveal that in #Maize, FIGL1 coordinates with dosage-sensitive #BRCA2 in modulating #meiotic #recombination, unlike their antagonistic relationship in #Arabidopsis.

One of the things I love about #MGM2023 #maize genetics meeting is the annual reminder of how badass maize genetics is. We’ll take this cool chromosome variant, link it to a phenotypic marker, put it in a fast flowering inbred, make that editable with CRiSPR and voila! Damn cool.

Until now, low efficiency was a major obstacle to using prime #editing in #maize. Qiao et al. have removed this barrier with their ePE5max system, optimizing prime editors to efficiently induce #heritable #mutations in #corn!
