Spatiotemporal Variations in Nectar Robbing and Its Effects on Reproduction in Diels (Lamiaceae).

Nectar robbing typically reduces nectar availability to pollinators, damages flower structure, and/or induces secondary robbing. Consequently, it may reduce pollen deposition and seed set, increase pollination efficiency and outcrossing, and/or not affect reproduction in some species. However, spatiotemporal variations in nectar robbing and their effects on plant reproduction have received little attention.

Knockout of TaOTUB1 homoeologs in wheat promotes increased grain yield and earlier flowering.

Flowering and subsequent seed development are not only the most crucial reproductive activities of plants but also key determinants of crop yield.
