Rice is calling for submissions to our Collection on Phytohormonal regulation in rice: advances in stress tolerance, yield improvement and molecular breeding. Phytohormones control all developmental stages and environmental responses in rice. Such regulation is precise, transient, and targeted at specific tissues and growth stages. Genes and regulatory elements involved in phytohormone biosynthesis, transport, and signaling have become primary targets for genetic manipulation to improve crop performance. The Green Revolution significantly increased rice yields by developing dwarf rice varieties that can efficiently respond to fertilizers without lodging, through the use of mutations in a gene encoding the gibberellin biosynthesis enzyme. We now need a second Green Revolution to improve rice production in infertile soils and even in stressful conditions for achieving sustainable agriculture. This issue of Rice, “Phytohormonal regulation in rice: advances in stress tolerance, yield improvement, and molecular breeding,” invites submission of research articles and reviews on topics such as, but not limited to: phytohormonal control of plant architecture, cellular signaling, physiological adaptations aimed at improving climate resilience and yield through transgenesis, genome editing, and molecular breeding.
