Splet13. jan. 2012 · AtSWEET11 and 12 localize to the plasma membrane of the phloem. Mutant plants carrying insertions in AtSWEET11 and 12 are defective in phloem loading, thus revealing a two-step mechanism of SWEET-mediated export from parenchyma cells feeding H(+)-coupled import into the sieve element-companion cell complex. SpletThe monitoring of heavy metal ions (HMIs) in rice phloem sap is of great significance for studying the migration and accumulation of HMIs in rice plants and, ultimately, for human health. However, achieving sensitive and selective electroanalysis of HMIs in such complex real samples is a huge challenge due to severe interference.
Apoplasmic loading in the rice phloem supported by the presence …
SpletBackground and aims: Although Oryza sativa (rice) is one of the most important cereal crops, the mechanism by which sucrose, the major photosynthate, is loaded into its phloem is still a matter of debate. Current opinion holds that the phloem loading pathway in rice could involve either a symplasmic or an apoplasmic route. Splet11. apr. 2024 · Fisher and Oparka (1992) referred to the process of sugar entering berry cells as "post-phloem transport". The metabolism of sucrose in the sink organ is a key driver that maintains phloem unloading continuously by keeping the sucrose gradients in the sink cells (Lecourieux et al. 2014). Therefore, studying the genes driving the "post-phloem ... maryland mva appointment online
The mechanism of phloem loading in rice (Oryza sativa)
Splet14. jul. 2024 · Phloem loading is the first crucial step for the transportation of sucrose to grains. However, phloem loading mechanisms in rice leaves and stems and their … SpletThe present paper attempts to correlate the plasmodesmatal connectivity between sieve element/companion cell complex and the adjacent cells (the minor vein configuration) – and implicitly the associate phloem loading mechanisms – with different types of climate. The nature of phloem loading of photosynthesis products – either symplastic or … SpletFigure 5: Hypothetical relationships between salinity tolerance and leaf Na+ concentration for three different species, denoted by a, b, and c for rice, durum wheat, and barley.
