Genetic compensation mechanisms for maintaining plant stem cell robustness ($) (Nature Genetics)

In 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…

How to pack chromatin in nuclear space? A plant-specific chromatin regulator associates with component of the nuclear periphery

https://doi.org/10.1105/tpc.18.00663 Mikulski et al. find that the PWO chromatin regulator interacts with a structural component of the nuclear periphery.  By Pawel Mikulski, Cell and Developmental Biology, John Innes Centre, Norwich, UK Background: DNA is wrapped around histone proteins forming…

Diverse metabolites across maize GWAS panel for dissecting maize genetic architecture (Plant Cell)

Plants 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)

The 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) ($)

To 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)

Key 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)

The demand for plant-based products will increase and must be doubled in the near future. Therefore, there is need for technological advancements and skillsets in all fields related to agriculture to successfully produce more efficiently than now. What could be done to speed up production to meet the…

Impact of Biolistic Transformation on the Genome

Liu et al. show that biolistic transformation can cause extensive damage and rearrangements, including deletions, duplications, chromosome fusions, and copy number variations. Plant Cell https://doi.org/10.1105/tpc.18.00613   By Jianing Liu and R. Kelly Dawe, Department of Genetics, University…

ABC transporter-mediated transport of glutathione conjugates enhances seed yield and quality in chickpea (Plant Physiol)

Identifying the genetic determinants of yield and quality traits is essential for crop improvement. Chickpea is the third-most cultivated legume species and is a prominent source of protein to global consumers. Genetic improvement of chickpea, in terms of enhancing its seed size and weight, has been…
