Analysis of a putative autophagy regulator during strawberry fruit ripening
Peralta-García, Raúl; Montero-Solís, Elena; Valpuesta-Fernández, Victoriano; Sánchez-Vera, Victoria (2022)Autophagy is a major catabolic pathway essential for cell homeostasis and conserved in almost all eukaryotes.

Sanchez-Vera, Victoria; Kenchappa, Chandra Shekar; Landberg, Katarina; Bressendorf, Simon; Schwarzbach, Stefan; Martin, Tom; Mundy, John; Petersen, Morten; Thelander, Mattias; Sundberg, Eva[et al.] (Autophagy / Landes Biosciences, 2017-09-25)Autophagy, a major catabolic process in eukaryotes, was initially related to cell tolerance to nutrient depletion. In plants autophagy has also been widely related to tolerance to biotic and abiotic stresses (through the ... -
Autophagy is required for strawberry fruit ripening
Sánchez-Sevilla, José F; Botella-Mesa, Miguel Ángel; Valpuesta-Fernández, Victoriano; Sánchez-Vera, Victoria (Frontiers Media SA, 2021-08-27)Autophagy is a catabolic and recycling pathway that maintains cellular homeostasis under normal growth and stress conditions. Two major types of autophagy, microautophagy and macroautophagy, have been described in plants. ... -
Autophagy mediates caloric restriction-induced lifespan extension in Arabidopsis.
Minina, Alyona; Sánchez-Vera, Victoria; Moschou, Panagiotis N.; Suárez-Marín, María Fernanda; Sundberg, Eva; Weih, Martin; Bozhkov, Peter V.[et al.] (Aging Cell/Blackwell publishing Ltd/Anatomical Society of Great Britain and Ireland, 2013-01-17)Caloric restriction (CR) extends lifespan in various heterotrophic organisms ranging from yeasts to mammals, but whether a similar phenomenon occurs in plants remains unknown. Plants are autotrophs and use their photosynthetic ... -
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 ... -
Extra spindle poles (Separase) controls anisotropic cell expansion in Norway spruce (Picea abies) embryos independently of its role in anaphase progression.

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 ... -
MS1/MMD1 homologs in the moss P. patens are required for male and female gametogenesis.
Landberg, Katarina; Lopez-Obando, Mauricio; Sanchez-Vera, Victoria; Sundberg, Eva; Thelander, Mattias (New Phytologist / Wiley, 2022-07-01)The Arabidopsis Plant HomeoDomain (PHD) proteins AtMS1 and AtMMD1 provide chromatin-mediated transcriptional regulation essential for tapetum-dependent pollen forma-tion. This pollen-based male gametogenesis is a derived ... -
