Adapting crops for climate change: regaining lost abiotic stress tolerance in crops

Frontiers in Science, Journal Year: 2024, Volume and Issue: 2

Published: Dec. 5, 2024

It is often stated that agricultural outputs need to increase substantially meet the demands for more food posed by a growing population. However, when accounting climate change, we argue current projected increases are unrealistic and realistic goal would be maintain yields per area of production. This will require breeding crops with increased tolerance abiotic stresses such as drought, salinity, waterlogging, high temperatures. can accomplished in one two ways: introducing stress genes into present high-yielding or increasing already tolerant orphan and/or wild plants. We first strategy easing restrictions on use gene editing technologies making substantial improvements cell-based phenotyping identify available pool crop its relatives. The success second depend number domestication selected order obtain comparable present-day cultivars. still too early conclude which strategies, rewilding (bringing lost from ancestors back domesticated crops) de novo (domesticating resilient plants underutilized directly), most effective future sustainable agriculture. given importance issue, some rapid action needs taken.

Agronomy, Journal Year: 2025, Volume and Issue: 15(3), P. 714 - 714

Published: March 15, 2025

Aegilops tauschii, a monocotyledonous annual grass, recognized as pivotal progenitor of modern wheat (Triticum aestivum L.), serves the D-genome donor in hexaploid wheat. This diploid species (2n = 2x 14, DD) harbors substantial reservoir genetic diversity, particularly terms biotic and abiotic stress resistance traits. The extensive allelic variation present its genome has been increasingly utilized for enhancement, through introgression breeding programs aimed at improving yield potential resilience. Heavy metal ATPases (HMAs), which belong to P-type ATPase superfamily are also known P1B-type ATPases, play crucial role transporting heavy metals maintaining ion homeostasis plant cells. HMAs have extensively studied model plants like Arabidopsis thaliana rice. However, this family not reported A. tauschii. Here, we conducted genome-wide identification bioinformatics analysis AetHMA gene resulting discovery total nine members. Among genes, six pairs large-block duplication mainly occur among four genes AetHMA2, AetHMA4, AetHMA8, AetHMA9. Additionally, there is one pair that consists tandem (AetHMA6: AetHMA7). All AetHMAs can be classified into groups (I–VI), further divided two branches: copper subclasses zinc subclasses. Initially, tauschii was grown 1/2 Hoagland nutrient solution subsequently exposed metals: (Zn), (Cu), manganese (Mn), cadmium (Cd). Following treatment, expression profiles were assessed. results indicated that, under stress, HMA members exhibited enhanced leaves, whereas most roots downregulated. In roots, except AetHMA5, levels other upregulated response Cd exposure. Furthermore, AetHMA4 diminishes tolerance yeast Mn by increasing absorption Mn, while AetHMA8 increases reducing Cd. study provides experimental data regarding function transport, regulation, detoxification elements
