The SYT6 protein from A. thaliana has recently been identified as a lipid transfer protein localized at membrane contact sites (MCS). MCS are regions where membranes of two organelles closely approach without membrane ... -
Detection and Measurement of Necrosis in Plants.
Minina, Elena A.; Filonova, Lada H; Sánchez-Vera, Victoria; Suárez-Marín, María Fernanda; Daniel, Geoffrey; Bozhkov, Peter V.[et al.] (Humana Press, 2013)
Necrosis plays a fundamental role in plant physiology and pathology. When plants or plant cell cultures are subjected to abiotic stress they initiate rapid cell death with necrotic morphology. Likewise, when plants are ... -
ER-plastid contact sites as molecular crossroads for plastid lipid biosynthesis
Huércano, Carolina; Moya-Barrientos, Miriam; Cuevas Corral, Oliver; Sánchez-Vera, Victoria; Ruiz-López, Noemí (BioMed Central, 2025-05-22)
Membrane contact sites are specialized regions where organelle membranes are in close proximity, enabling lipid transfer while preserving membrane identity. In plants, ER‒chloroplast contact sites are critical for maintaining ... -

Cardeñas Echevarría, Carlos; Moya-Barrientos, Miriam; Sánchez-Vera, Victoria; Ruiz-López, Noemí (2024)
Estudios recientes han identificado las proteínas SYT6, las cuales se localizan en puntos de contacto entre el retículo endoplasmático y vesículas secretoras gemadas del trans-Golgi network. Estas proteínas se caracterizan ... -
Extra spindle poles (Separase) controls anisotropic cell expansion in Norway spruce (Picea abies) embryos independently of its role in anaphase progression.
Moschou, Panagiotis N.; Savenkov, Eugene I; Minina, Elena A.; Fukada, Kazutake; Reza, Salim Hossain; Gutiérrez-Beltrán, Emilio; Sánchez-Vera, Victoria; Suárez-Marín, María Fernanda; Hussey, Patrick J.; Smertenko, Andrei; Bozhkov, Peter V.[et al.] (Wiley-Blackwell, 2016-05-27)
The caspase-related protease separase (EXTRA SPINDLE POLES, ESP) plays a major role in chromatid disjunction and cell expansion in Arabidopsis thaliana. Whether the expansion phenotypes are linked to defects in cell division ... -
Identification of NTMC2T5, a new lipid transfer protein family at ER-chloroplast contact sites involved in stress response
Huércano Rubens, Carolina; Percio-Vargas, Francisco; Sánchez-Vera, Victoria; Morello-López, Jorge; Salas-Liñán, Joaquín J; Ruiz-López, Noemí[et al.] (2022-09)
Plants are sessile organisms and they have perfected a complex molecular signalling network to detect and respond to different environmental stresses. In plants, fatty acid synthesis takes place at chloroplasts, and they ... -
Localization and characterization of SMP-containing proteins in Membrane Contact Sites
Huércano Rubens, Carolina; Sánchez-Vera, Victoria; Percio-Vargas, Francisco; Morello-López, Jorge; Botella-Mesa, Miguel Ángel; Ruiz-López, Noemí[et al.] (2021)
Membrane contact sites (MCS) are discrete regions where two membranes from different organelles are closely apposed (10-30 nm). In those regions, non-vesicular transfer of lipids takes place to ensure proper organelle ... -
