Photoassimilate translocation
WebFeb 2, 2024 · Our observation suggests that AtFLO2 is strongly involved in regulation of translocation and transport of assimilates, and contributes greatly to quality control of the various processes involving substance supply or transfer, such as photoassimilation, leaf enlargement, yield of seeds in a silique and accumulation of seed storage compounds. WebDec 15, 2024 · The transport of photoassimilates through the phloem is performed predominantly in the form of sucrose or compounds derived from raffinose and stachyose. In melon plants, sucrose, raffinose, and stachyose are the major carbohydrates translocated in the phloem (Chrost and Schmitz, 1997 ).
