| 1 | Sucrose transporter2 contributes to maize growth,development,and crop yield显示文摘During daylight, plants produce excess photosynthates, including sucrose, which is temporarily stored in the vacuole. At night, plants remobilize sucrose to sustain metabolism and growth. Based on homology to other sucrose transporter(SUT) proteins, we hypothesized the maize(Zea mays) SUCROSE TRANSPORTER2(ZmSUT2)protein functions as a sucrose/Htsymporter on the vacuolar membrane to export transiently stored sucrose.To understand the biological role of ZmSut2, we examined its spatial and temporal gene expression, determined the protein subcellular localization, and characterized loss-offunction mutations. ZmSut2 mRNA was ubiquitously expressed and exhibited diurnal cycling in transcript abundance. Expressing a translational fusion of ZmSUT2 fused to a red fluorescent protein in maize mesophyll cell protoplasts revealed that the protein localized to the tonoplast. Under field conditions, zmsut2 mutant plants grew slower, possessed smaller tassels and ears, and produced fewer kernels when compared to wild-type siblings. zmsut2 mutants also accumulated two-fold more sucrose, glucose, and fructose as well as starch in source leaves compared to wild type. These findings suggest(i) ZmSUT2 functions to remobilize sucrose out of the vacuole for subsequent use in growing tissues; and(ii) its function provides an important contribution to maize development and agronomic yield. | Kristen A.Leach Thu M.Tran Thomas L.Slewinski Robert B.Meeley David M.Braun | 2017 | Journal of Integrative Plant Biology2017，59，6： | 8 |

| 3 | Maize Carbohydrate Partitioning Defective33 Encodes an MCTP Protein and Functions in Sucrose Export from Leaves显示文摘To sustain plant growth,development,and crop yield,sucrose must be transported from leaves to distant parts of the plant,such as seeds and roots.To identify genes that regulate sucrose accumulation and transport in maize(Zea mays),we isolated carbo/iydrafe part/f/ofi/ngf defecf/Ve33(cpd33),a recessive mutant that accumulated excess starch and soluble sugars in mature leaves.The cpd33 mutants also exhibited chlorosis in the leaf blades,greatly diminished plant growth,and reduced fertility.Cpd33 encodes a protein containing multiple C2 domains and transmembrane regions.Subcellular localization experiments showed the CPD33 protein localized to plasmodesmata(PD),the plasma membrane,and the endoplasmic reticulum.We also found that a loss-of-function mutant of the CPD33 homolog in Arabidopsis,QUIRKY,had a similar carbohydrate hyperaccumulation phenotype.Radioactively labeled sucrose transport assays showed that sucrose export was significantly lower in cpd33 mutant leaves relative to wild-type leaves.However,PD transport in the adaxial-abaxial direction was unaffected in cpd33 mutant leaves.Intriguingly,transmission electron microscopy revealed fewer PD at the companion cell-sieve element interface in mutant phloem tissue,providing a possible explanation for the reduced sucrose export in mutant leaves.Collectively,our results suggest that CPD33 functions to promote symplastic transport into sieve elements. | Thu M.Tran Tyler J.McCubbin Saadia Bihmidine Benjamin T.Julius R.Frank Baker Martin Schauflinger Clifford Weil Nathan Springer Paul Chomet Ruth Wagner Jeff Woessner Karen Grote Jeanette Peevers Thomas L.Slewinski David M.Braun | 2019 | Molecular Plant2019，12，9： | 1 |

| 5 | Cell-type resolved transcriptomic approaches for dissecting selective vulnerability in neurodgeneration显示文摘A common feature among neurodegenerative conditions is that ce rtain neuronal populations are selectively vulnerable to loss(Fu et al.,2018).By corollary,other neurons are selectively resilient,suggesting they may possess unique features that support their survival.U nderstanding the basis of neuronal resilience or vulnerability would provide a logical strategy to identify factors that could be targeted therapeutically. | Caleb A.Wood Nicholas M.Tran | 2024 | Neural Regeneration Research2024，19，7： | 0 |
