“…However, it is also important to note that other genes located within the Stg QTL regions studied in sorghum, both characterized and uncharacterized, have the potential to alter plant architecture via various pathways and mechanisms that confer stay-green. Despite the potential regulatory challenges in gene-editing and difficulties working with recalcitrant crops such as sorghum ( Massel et al 2021 ; Wong et al 2022 ), the combination of the two approaches of (i) expressing SbPIN s attached to plant tissue-specific promoters and (ii) editing regulatory regions or the coding sequences of SbPIN s through CRISPR/Cas9 technology should be a good strategy for designing future crops with desirable plant architectures to overcome climate change. Experiments could also include commercial lines with various tillering genotypes to act as controls and checks.…”

Plant architecture modification (e.g. short-stature crops) is one of the key outcomes of modern crop breeding for high-yielding crop varieties. In cereals, delayed senescence, or stay-green, is an important trait which enable post-anthesis drought stress adaptation. Stay-green crops can prolong photosynthetic capacity during grain filling period under post-anthesis drought stress, which is essential to ensure grain yield is not impacted under drought stress conditions. Although various stay-green quantitative trait loci (QTLs) have been identified in cereals, the underlying molecular mechanisms regulating stay-green remain elusive. Recent advances in various gene-editing technologies have provided avenues to fast-track crop improvement, such as the breeding of climate resilient crops in the face of climate change. We present in this viewpoint the focus on using sorghum as the model cereal crop, to study PIN-FORMED (PIN) auxin efflux carriers as means to modulate plant architecture, and the potential to employ it as an adaptive strategy to address the environmental challenges pose by climate uncertainties.
