During the last years, a great effort has been dedicated at development and employment of diverse approaches for achieving more stress-tolerant climate-flexible crops sustainable yield increases to meet food energy demands future. The ongoing climate change is in fact leading frequent extreme events with negative impact on production, such as increased temperatures, drought, soil salinization well invasive arthropod pests diseases. In this review, "green strategies" (e.g., chemical priming, root-associated microorganisms), advanced technologies genome editing, high-throughput phenotyping) are described basis most recent research evidence. Particularly, attention focused potential use context climate-smart agriculture (the so called "next generation") improve plant tolerance resilience abiotic biotic stresses. addition, gap between results obtained controlled experiments those from application these real field conditions (lab step) also discussed.

Sustainable agricultural management of saline soils in arid and semi-arid Mediterranean regions through halophytes, microbial and soil-based technologies

Environmental and Experimental Botany, Journal Year: 2023, Volume and Issue: 212, P. 105397 - 105397

Published: May 29, 2023

Soil salinization is an important global issue since marginal salt-affected soils have harmful consequences in agriculture and ecosystems. This article reviews different sustainable strategies adopted for soil reclamation Mediterranean climates. An innovative approach to salinity management includes a wide range of technologies, such as: phytoremediation, phytodesalination, vegetative bioremediation, amendments application Technosols as well inoculation with beneficial microorganisms like plant growth promoting bacteria arbuscular mycorrhizal fungi. Besides that, the role halophyte crops accelerating area's recovery while providing food feed, halophilic new bioinoculant production, are discussed. We conclude that combined use plant, soil- microbial-based technologies valuable option relieve saline stress exposure improve yield conditions.

EARLY BUD-BREAK 1 and EARLY BUD-BREAK 3 control resumption of poplar growth after winter dormancy

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Feb. 18, 2021

Abstract Bud-break is an economically and environmentally important process in trees shrubs from boreal temperate latitudes, but its molecular mechanisms are poorly understood. Here, we show that two previously reported transcription factors, EARLY BUD BREAK 1 (EBB1) SHORT VEGETATIVE PHASE-Like (SVL) directly interact to control bud-break. EBB1 a positive regulator of bud-break, whereas SVL negative negatively regulates expression. We further report the identification characterization EBB3 gene. temperature-responsive, epigenetically-regulated, bud-break provides direct link activation cell cycle during AP2/ERF factor positively CYCLIND3.1 Our results reveal architecture putative regulatory module links temperature-mediated with cycle.

Biodiversity, climate change, and adaptation in the Mediterranean

Ecosphere, Journal Year: 2022, Volume and Issue: 13(4)

Published: April 1, 2022

Abstract Potential for, and limits to, adaptation to environmental changes are critical for resilience risk mitigation. The Mediterranean basin is a mosaic of biodiversity‐rich ecosystems long affected by human influence, whose now questioned climate change. After reviewing the different components biological adaptation, we present main characteristics marine terrestrial biodiversity in pressures they face. Taking climatic trends into consideration, discuss adaptive potential range dominated species without active dispersal. We argue that high heterogeneity landscapes seascapes constitutes laboratory study when conditions change rapidly may provide opportunities adaptability ecosystems. Adaptive management can should harness nature‐based solutions offered both ecological evolutionary processes increasing

Transcriptional Regulation of Drought Response in Arabidopsis and Woody Plants

Frontiers in Plant Science, Journal Year: 2021, Volume and Issue: 11

Published: Jan. 8, 2021

Within the context of global warming, long-living plants such as perennial woody species endure adverse conditions. Among all abiotic stresses, drought stress is one most detrimental stresses that inhibit plant growth and productivity. Plants have evolved multiple mechanisms to respond stress, among which transcriptional regulation key mechanisms. In this review, we summarize recent progress on response by transcription factor (TF) families, include abscisic acid (ABA)-dependent ABA-responsive element/ABRE-binding factors (ABRE/ABF), WRKY, Nuclear Factor Y well ABA-independent AP2/ERF NAC in model Arabidopsis . We also review what known species, particularly Populus , due its importance relevance economic ecological processes. discuss opportunities for a deeper understanding with development high-throughput omics analyses advanced genome editing techniques.

Influence of Climate Change on Metabolism and Biological Characteristics in Perennial Woody Fruit Crops in the Mediterranean Environment

Horticulturae, Journal Year: 2022, Volume and Issue: 8(4), P. 273 - 273

Published: March 22, 2022

The changes in the state of climate have a high impact on perennial fruit crops thus threatening food availability. Indeed, climatic factors affect several plant aspects, such as phenological stages, physiological processes, disease-pest frequency, yield, and qualitative composition tissues derived products. To mitigate effects parameters variability, plants implement strategies defense, by changing trends, altering physiology, increasing carbon sequestration, metabolites synthesis. This review was divided into two sections. first provides data change last years general consideration their impact, mitigation, resilience production crops. second section reviews consequences industry woody models (evergreen deciduous trees). research focused on, citrus, olive, loquat evergreen trees examples; while grape, apple, pear, cherry, apricot, almond, peach, kiwi, fig, persimmon species. Perennial originated complex decisions valuable long period involving economic technical problems that farmers may quickly case annual However, low flexibility is balanced long-life cycle.

Abstract Citrus plants routinely experience a broad range of biotic and abiotic stress that occur either concurrently or sequentially in the field, causing huge losses yield. Hence, cultivated citrus tolerate only one type are insufficient to maintain productivity as climate changes. Plants primarily develop delicate regulatory mechanisms detect, transduce respond adverse environmental conditions. Therefore, elucidating physiological, biochemical molecular underlying dynamic response multiple stresses is prerequisite for determining targets genetic improvement programs citrus. In this review, we pinpoint current understanding physiological basis tolerance stress.

Synthetic Polyploidy in Grafted Crops

Frontiers in Plant Science, Journal Year: 2020, Volume and Issue: 11

Published: Nov. 5, 2020

Synthetic polyploids have been extensively studied for breeding in the last decade. However, use of such genotypes at agronomical level is still limited. Polyploidization known to modify certain plant phenotypes while leaving most fundamental characteristics apparently untouched. For this reason, polyploid can be very useful improving specific traits crop varieties as quality, yield, or environmental adaptation. Nevertheless, mechanisms that underlie polyploidy-induced novelty remain poorly understood. Ploidy-induced might also include some undesired effects need considered. In case grafted composite crops, benefits provided both by rootstock´s adaptation soil conditions and scion´s excellent yield quality. Thus, crops provide an extraordinary opportunity exploit artificial polyploidy, independently applied explored root and/or scion level, increasing chances finding successful combinations. The synthetic tetraploid rootstocks may enhance biotic abiotic stresses perennial apple citrus. their commercial production Here, we will review current prospective polyploidy rootstock improvement implications combination. aim insight into methods used generate select limitations, on phenotype (anatomy, function, stresses) potential agronomic relevance scions context climate change.
