N-methyladenosine (mA) RNA modification is the most prevalent messenger RNA (mRNA) modification in eukaryotes and plays critical roles in the regulation of gene expression. mA is a reversible RNA modification that is deposited by methyltransferases (writers) and removed by demethylases (erasers). The function of mA erasers in plants is highly diversified and their roles in cereal crops, especially in reproductive development essential for crop yield, are largely unknown.

However, prioritising yield often compromises improvement of other key traits, including grain quality, which is tedious and time-consuming to measure because of the frequent involvement of destructive phenotyping methods. Recently, non-destructive methods such as hyperspectral imaging (HSI) have gained attention in the food industry for studying wheat grain quality.

These non-essential metals and metalloids are toxic to all organisms impacting crop yields and human health. Crop plants exposed to high concentrations of these metals leads to perturbed mineral homeostasis, decreased photosynthesis efficiency, inhibited cell division, oxidative stress, genotoxic effects and subsequently hampered growth.

This will come at a significant environmental cost, and a shift toward plant-based protein sources would therefore provide major benefits. While legumes provide substantial amounts of plant-based protein, cereals are the major constituents of global foods, with wheat alone accounting for 15-20% of the required dietary protein intake.

Breeders have harnessed natural diversity for inflorescence architecture to improve yields, and induced genetic variation could provide further gains. Wheat is a vital source of protein and calories; however, little is known about the genes that regulate the development of its inflorescence.

Vetch seeds have desirable nutritional characteristics and are often used to feed ruminant animals. Although transcriptomes are available for vetch, problems with genetic transformation and plant regeneration hinder functional gene studies in this legume species.

Here, we report the annotated, near-complete genome sequence of Allorhizobium vitis K377, a phytopathogenic strain isolated from a grapevine in South Australia. The assembled genome sequence is 6.40 Mb long, with 5,855 predicted protein-coding sequences, 56 tRNAs, and 12 rRNAs, and contains (tartrate metabolism; chromosomal) and nopaline synthesis, uptake, and catabolic genes (tumor-inducing plasmid-encoded).

More than 70% of eukaryotic genomes are transcribed into RNA transcripts, the majority of these transcripts are noncoding protein, and their biological functions are largely unknown. Over the last decade, the application of high-throughput sequencing technologies has led to the description of almost all cellular coding and noncoding RNA transcripts except perhaps for those transcripts that are lowly abundant or those present only in specific cells that are underrepresented in sampled tissue(s). An often underrepresented class of noncoding are long noncoding RNAs (lncRNAs), and these often play key regulatory functions for many biological processes such as cell identity and cell division.
