Development of genome-wide SNP markers for barley via reference- based RNA-Seq Analysis (Front Plant Sci)
Plant Science Research WeeklyThe availability of marker-assisted systems is key for crop improvement, allowing trait selection by identifying consensus polymorphisms. However, for discriminating between related strains, these DNA markers are limited, time-consuming and expensive. Here, Tanaka et al. developed a RNA-Seq-based genotyping…
Generation of herbicide tolerance traits and a new selectable marker in wheat using base editing (Nature Plants)
Plant Science Research WeeklyNowadays, weeds represents a major problem to agriculture due to the limited availability and expense of tools to manage them. Using new technologies to create herbicide-tolerant, non-transgenic varieties could improve weed control. Here, Li et al. analyzed multiallelic editing of the wheat TaALS (encoding…
Genetic compensation mechanisms for maintaining plant stem cell robustness ($) (Nature Genetics)
Plant Science Research WeeklyIn shoot meristems, the CLAVATA (CLV)-WUSCHEL(WUS) signaling module contributes to the continuous stem cell proliferation for plant development. In Arabidopsis, core CLV-WUS signaling includes the peptide ligand CLV3 and its receptor protein kinase CLV1 together with the transcription factor WUS. These…

Diverse metabolites across maize GWAS panel for dissecting maize genetic architecture (Plant Cell)
Plant Science Research WeeklyPlants can produce metabolites that are directly involved in various biological pathways. Identifying variations of specific metabolites in different genotypes would facilitate the understanding underlying complex genetic architecture of maize. One of most representative natural diversity panels, the…
Moonlighting activities and control of meristem maintenance in maize ($) (Nature Plants)
Plant Science Research WeeklyThe phosphorylated disaccharide trehalose 6-phosphate (T6P) is a regulator of meristem fate. Mutations in enzymes related to T6P metabolism (such as TPS, the synthase, or the phosphatase trehalose 6-phosphate phosphatase TPP, i.e., RAMOSA3 that dephosphorylates T6P to trehalose), are linked to defects…
Review: CRISPR/Cas genome editing and precision plant breeding in agriculture (Annu Rev Plant Biol) ($)
Plant Science Research WeeklyTo fulfill global food demand in the near future, plant researchers keep pursuing simpler and faster crop breeding strategies. CRISPR/Cas systems have been developed as a powerful tool for plant genome editing. In this review, Chen et al. highlight in detail advances in CRISPR/Cas9 and its variants and…
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…
Q&A: Modern crop breeding for future food security (BMC Biology)
