Accelerated breeding of plant species has the potential to help challenge environmental and biochemical cues to support global crop security. We demonstrate the over-expression of in -mediated transformed cassava ( Crantz; cultivar 60444) to trigger early flowering in glasshouse-grown plants. An event seldom seen in a glasshouse environment, precocious flowering and mature inflorescence were obtained within 4-5 months from planting of stem cuttings. Manual pollination using pistillate and staminate flowers from clonal propagants gave rise to viable seeds that germinated into morphologically typical progeny. This strategy comes at a time when accelerated crop breeding is of increasing importance to complement progressive genome editing techniques.
植物物种的加速育种有潜力帮助应对环境和生化线索,以支持全球作物安全。我们展示了通过介导转化木薯(Crantz;品种60444)的过表达,来促使温室种植的植物提前开花。在温室环境中很少见到的情况是,从扦插茎种植后的4 - 5个月内就实现了早熟开花和成熟花序。使用克隆繁殖体的雌花和雄花进行人工授粉产生了可存活的种子,这些种子萌发成形态典型的后代。这一策略出现之际,加速作物育种对于补充先进的基因组编辑技术愈发重要。
