Miguel Pineros

About

Miguel Pineros is a Research Plant Physiologist at the USDA-ARS Robert W. Holley Center for Agriculture & Health and an Adjunct Associate Professor in the School of Integrative Plant Science, Plant Biology Section. His research interests include crop adaptation to soil abiotic stresses and the bioavailability of iron, zinc, and phytochemicals. Pineros's work involves understanding plant physiological responses to environmental stresses, with a focus on improving crop resilience and nutritional quality. His contributions include identifying genetic variations that influence plant architecture, such as a mutation causing 'weeping' in apple trees, which has implications for orchard fruit production. He is actively involved in advancing agricultural research through his role at USDA-ARS and his academic appointment, contributing to the development of sustainable and productive crop systems.

• Plant HKT Channels: An Updated View on Structure, Function and Gene Regulation

  International Journal of Molecular Sciences · 2021 · 72 citations

  symporters. Nevertheless, even within these two classes, there is a high functional diversity that, to date, cannot be explained at the molecular level. The high complexity is also reflected at the regulatory level. HKT expression is modulated at the level of transcription, translation, and functionality of the protein. Here, we summarize and discuss the structure and conservation of the HKT channel family from algae to angiosperms. We also outline the latest findings on gene expression and the…

• YSL3-mediated copper distribution is required for fertility, seed size and protein accumulation in <i>Brachypodium</i>

  PLANT PHYSIOLOGY · 2021 · 50 citations

  Addressing the looming global food security crisis requires the development of high-yielding crops. In agricultural soils, deficiency in the micronutrient copper significantly decreases grain yield in wheat (Triticum aestivum), a globally important crop. In cereals, grain yield is determined by inflorescence architecture, flower fertility, grain size, and weight. Whether copper is involved in these processes, and how it is delivered to the reproductive organs is not well understood. We show that…

• Alternative Splicing Underpins the ALMT9 Transporter Function for Vacuolar Malic Acid Accumulation in Apple

  Advanced Science · 2024-03-21 · 24 citations

  articleOpen accessCorresponding

  Vacuolar malic acid accumulation largely determines fruit acidity, a key trait for the taste and flavor of apple and other fleshy fruits. Aluminum-activated malate transporter 9 (ALMT9/Ma1) underlies a major genetic locus, Ma, for fruit acidity in apple, but how the protein transports malate across the tonoplast is unclear. Here, it is shown that overexpression of the coding sequence of Ma1 (Ma1α) drastically decreases fruit acidity in "Royal Gala" apple, leading to uncovering alternative splici…

• Designing Plant-Driven Actuators for Robots to Grow, Age, and Decay

  Designing Interactive Systems Conference · 2024-06-29 · 17 citations

  articleOpen access

  Designing plant-driven actuators presents an opportunity to create new types of devices that grow, age, and decay, such as robots that embody these qualities in their physical structure. Plant-robot hybrids that grow and decay incorporate unpredictable and gradual transformations inherent across living organisms and suggest an alternative to the design principles of immediacy, responsiveness, control, accuracy, and durability commonly found in robotic design. To explore this, we present a design…

• Recycled Phosphorus Bioamendments from Wastewater Impact Rhizomicrobiome and Benefit Crop Growth: Sustainability Implications at Water-Food Nexus

  Environmental Science & Technology · 2025-01-22 · 15 citations

  article

  Phosphorus recovery through enhanced biological phosphorus removal (EBPR) processes from agricultural wastes holds promise in mitigating the impending global P shortage. However, the complex nutrient forms and the microbial augments, expected to exert a profound impact on crop rhizomicrobiome and thus crop health, remained unexplored. In this study, we investigated the impacts of EBPR biosolids on crops growth and rhizomicrobiome in comparison to chemical fertilizer and Vermont manure compost. O…
