Nat. Plants. The current rate of crop plant breeding, limited by the long generation time of crop plants, is insufficient to address the needs caused by the enormous increase in the human population accompanied by climate change. Watson et al. have recently presented a method called ‘Speed breeding’…

Humans have been domesticating plants for 10,000 years, having an impact on the gene pools of multiple species chiefly through selective breeding approaches. Although plant domestication ensured food availability to early civilizations, plants were, and still are, mainly selected based on their morphology…

“If the current trend continues, there could be more plastic than fish by weight in the oceans by 2050” writes MacArthur in her Editorial, “Beyond plastic waste” (10.1126/science.aao6749). In three Perspective articles, challenges and opportunities to reduce plastic waste and improve its production…

Previously, the authors identified an Arabidopsis mutant that shows resistance to a widespread oomycete pathogen. In this new work, Wang et al. identified the Phytophthora sojae susceptible gene locus, PSS1, which encodes a plasma-membrane localized glycine-rich protein. When introduced into soybean…

The ability to generate transgenic plants has revolutionised plant science research.  However, many species and genotypes remain challenging and time-consuming to transform.  Zhao et al. provide a novel and potentially ground-breaking method of transgene delivery.  In the presence of a magnetic field,…

Assessing the function of genes active in zygotes and egg cells is difficult due to the inaccessibility of the target tissues.  Koiso et al. isolated rice egg cells and maize zygotes using a method similar to that for extracting leaf protoplasts.  They then optimized a PEG-Ca2+ transfection protocol…

Reading books by the light of nanobionic plants sounds like something out of a scifi book. However, scientists have been working for many years on engineering light-emitting plants based on the luciferase enzyme. This work has been limited largely by the need to overcome the toxicity of adding to much…

CRISPR/Cas9 genome editing has rapidly become a powerful tool in modern plant science research.  However, issues of low editing efficiencies and off-target mutations remain.  LeBlanc et al. hypothesised that subjecting plants to high temperature stress, mimicking the optimal operating temperature of…
