Expression of FLOWERING LOCUS C differentiates summer and winter biotypes of Camelina sativa (Plant Direct)

Camelina sativa is a member of the Brassicaceae family that is grown as an oilseed crop. It has summer and winter flowering biotypes, the latter of which requires vernalization to induce flowering.  These two biotypes allow for double-cropping, and the winter-flowering biotype can also be used as a…

Regulation of Photosynthesis: Shedding Light on Protein Acetylation

Koskela and Brünje et al. identified a chloroplast protein acetyltransferase, which is required for the regulation of light harvesting in Arabidopsis. Plant Cell (2018) https://doi.org/10.1105/tpc.18.00155. by Minna M. Koskela, Annika Brünje, Iris Finkemeier, Paula Mulo   Background: Plants…

Enzyme helps as a transcription factor in lignin production

Arjen Dijkgraaf | Wednesday, July 4, 2018 (Originally published in C2W Boeken. Translation by Google Translate) In poplars a protein appears to have a bizarre double function: it makes building blocks for amino acids but also regulates the production of lignin. It could be a new way to create…

NLR mutations suppressing immune hybrid incompatibility (Plant Physiol)

Hybrid incompatibility (HI) is effectively the opposite of hybrid vigor, and indicates a deleterious effect arising from the combination of two genomes.  Because of reduced fitness of the hybrids, HI can be considered as contributing towards speciation. In Arabidopsis thaliana, HI has been recognized…

A Tale of Three Studies: Uncovering the Crucial Roles of m6A Readers

The story behind m6A (methylation of the N6 position of adenosine), the most common internal mRNA modification in eukaryotes, has long been a source of intrigue. This epitranscriptomic mark is deposited at specific mRNA sequences by m6A writers and removed by m6A erasers. The m6A marks recruit and anchor…

Divide and Conquer: High-Throughput Screening of Chlamydomonas Cell Cycle Mutants

Cell division is essential for growth and reproduction. The cell cycle machinery is well conserved between yeast and animals, but whether this conservation extends to the plant lineage is not clear, having diverged over two billion years ago: ample time and opportunity for divergence in sequence and…

CRISPR/Cas9-mediated gene targeting in Arabidopsis using sequential transformation (Nature Comms)

Genome modification is a powerful tool, yet precise genome engineering in plants remains challenging. Miki et al. report on the sequential transformation method for gene targeting in Arabidopsis. The parental plants expressing CRISPR/Cas9 under the egg cell- and early embryo-specific DD45 promoter were…

The Long and the Short of It: GA 2-oxidaseA9 Regulates Plant Height in Wheat

The discovery of semidwarfing genes in wheat and rice was a crucial turning point of the Green Revolution in the late 1960s. The Green Revolution aimed to maintain per capita food supplies worldwide despite the projected doubling of global population by the end of the 20th century. Its main features…

A Kinesin-14 motor activates neocentromeres to promote meiotic drive in maize

Meiotic drive is essentially a subversion of meiosis such that particular regions or alleles are preferentially favored for transmission to the progeny. Abnormal chromosome 10 (Ab10) is a classic example of meiotic drive in maize that converts heterochromatic chromosomal knobs into motile ‘neocentromeres’.…
