Controlled atmosphere storage modulates the exocarp-color and mesocarp-softening synchronization in ´Hass´ avocado

Camila Arancibia-Guerra, Gerardo Núñez‐Lillo, Nathalie Kühn, Excequel Ponce et autres

Controlled atmosphere storage is a key postharvest technology for extending the commercial life of ´Hass´ avocado ( Persea americana Mill.) during long distance transport. However, color-firmness desynchronization, where the mesocarp softens before the exocarp develops its characteristic black color, remains a major …

Decoding the Hayward kiwi (Actinidia deliciosa var Hayward) genome: transcriptomic responses to drought and salinity and AdhSAP4’s role in salinity stress responses

Samuel Parra, Gerardo Núñez‐Lillo, Patricio Tapia-Reyes, Emerson Clovis Carrasco-Lozano et autres

var. Hayward). Stress-associated proteins (SAPs), defined by conserved A20/AN1 zinc finger domains, are emerging as key modulators of plant stress responses. Despite their relevance in model plants, their functional roles in kiwi remain unexplored. In this study we assembled a high-quality haploid …

Integration of lipidomics and transcriptomics provides new insights into lipid metabolism in response to water deficit in Prunus spp. rootstock leaves

Patricio Olmedo, Gerardo Núñez‐Lillo, Guillermo Toro, Ismael Opazo et autres

The mechanisms underlying the role of lipids in the response to water deficit in Prunus species have not yet been elucidated. To investigate these, a drought-tolerant rootstock (R40) and a drought-sensitive rootstock (R20) were exposed to well-watered (WW) and water deficit (WD) …

Combined multi-omics and physiological approaches to elucidate drought-response mechanisms of durum wheat

Osvin Arriagada, Claudio Meneses, Romina Pedreschi, Gerardo Núñez‐Lillo et autres

Introduction: Durum wheat is the most important cereal in the Mediterranean regions, where drought negatively affects grain yield. Therefore, our objective was to perform a multi-omics and integration analysis in conjunction with physiological trials to improve our understanding of drought tolerance mechanisms …

Enhanced auxin signaling promotes root-hair growth at moderately low temperature in Arabidopsis thaliana

Victoria Berdion Gabarain, Gerardo Núñez‐Lillo, Aleš Pěnčík, Mariana Carignani Sardoy et autres

Root hairs (RHs) are mixed tip- and non-tip-growing protrusions derived from root epidermal cells that play essential roles in nutrient and water uptake, root anchorage, and interactions with soil microorganisms. Nutrient availability and temperature are critical and interconnected factors for sustained plant …

Two antagonistic gene regulatory networks drive Arabidopsis root hair growth at low temperature linked to a low‐nutrient environment

Tomás Urzúa Lehuedé, Victoria Berdion Gabarain, Miguel Angel Ibeas, Hernán Salinas‐Grenet et autres

Root hair (RH) cells can elongate to several hundred times their initial size, and are an ideal model system for investigating cell size control. Their development is influenced by both endogenous and external signals, which are combined to form an integrative response. …

Enhanced auxin signaling hub triggers root hair growth at moderate low temperature in Arabidopsis thaliana

Victoria Berdion Gabarain, Gerardo Núñez‐Lillo, Aleš Pěnčík, Miguel Angel Ibeas et autres

Abstract Root hairs (RH) as a mixed tip- and non-tip growing protrusions that develop from root epidermal cells are important for nutrient and water uptake, root anchoring, and interaction with soil microorganisms. Although nutrient availability and temperature are critical interlinked factors for …
