RNA sequence analysis of diseased groundnut (<i>Arachis hypogaea</i>) reveals the full genome of groundnut rosette assistor virus (GRAV)

The complete genome sequences for two variant isolates of groundnut rosette assistor virus (GRAV) have been determined from symptomatic groundnut plants in western Kenya. The sequences of the two GRAV isolates (sc7.1 and sc7.2) are 84.2% identical at the nucleotide level and 98.5% identical at the coat protein level. The variants sc7.1 and sc7.2 comprise 5850 and 5879 nucleotides respectively, and show similar genome organizations with 7 predicted ORFs (P0, P1, P2, P3a, P3 (coat protein, CP), P4 (movement protein, MP) and P5 (coat protein-readthrough protein, CP-RT). Currently, GRAV is an unassigned virus in the Luteoviridae family, due to the fact that only the sequence of the coat protein was previously obtained. The presence of both ORF0 and ORF 4 within the genome sequence determined in the current work suggest that GRAV should be classified as a member of the genus Polerovirus

One hundred important questions facing plant science: an international perspective

Hundred Important Questions Facing Plant Science Research’ project aimed to capture a global snapshot of the current issues and future questions facing plant science. This revisiting builds on the original 2011 paper. Over 600 questions were collected from anyone interested in plants, which were reduced to a final list of 100 by four teams of global panellists. There was remarkable consensus on the most important topics between the global subpanels. We present the top 100 most important questions facing plant science in 2022, ranging from how plants can contribute to tackling climate change, to plant-defence priming and epigenome plasticity. We also provide explanations of why each question is important. We demonstrate how focussing on climate change, community and protecting plant life has become increasingly important for plant science over the past 11 years. This revisiting illustrates the collaborative and international need for long-term funding of plant science research, alongside the broad community-driven efforts to actively ameliorate and halt climate change, while adapting to its consequences
