Abstract Ancient trees are natural wonders because of their longevity, having lived for hundreds or thousands years, and ability to withstand changing environments a variety stresses. These long-lived have sophisticated defense mechanisms, such as the production specialized plant metabolites (SPMs). In this review, we provide an overview major biotic abiotic stresses that often face, well analysis renowned ancient tree species unique protective SPMs against environmental stressors. We also discuss synthesis accumulation defensive induced by factors endophytes in these trees. Furthermore, conducted comparative genomic 17 discovered significant expansions SPM biosynthesis gene families species. Our comprehensive review reveals crucial role high resistance trees, providing novel resource defense, crop improvement even pharmaceutical industry.

The development of perennial crops holds great promise for sustainable agriculture and food security. However, the evolution transition between perenniality annuality is poorly understood. Here, using two Brassicaceae species, Crucihimalaya himalaica Erysimum nevadense, as polycarpic models, we reveal that from to biennial annual flowering behavior a continuum determined by dosage three closely related MADS-box genes. Diversification expression patterns, functional strengths, combinations these genes endows species with potential adopt various life-history strategies. Remarkably, find single gene among sufficient convert winter-annual or plants into plants. Our work delineates genetic basis diverse strategies in lays groundwork generation future.

Abstract Plants store nutrients, including the micronutrient iron, in bioavailable forms to support growth subsequent seasons. The perennial lifestyle is preponderant nature. Arabis alpina a model organism with particular architecture of branches having proximal (PZ) and distal annual (AZ) stem zones distinct anatomy physiology. PZ undergoes secondary stores carbon‐rich macromolecules. Here, we investigated iron homeostasis versus AZ. We localized internodes AZ using Perls staining ferritin immunodetection wild‐type Pajares (Paj) perpetual flowering 1 mutant. mined transcriptome data developing Iron accumulated at various development stages levels were ca. two‐fold higher than AZ, irrespective flowering. was predominantly located within plastid‐bound ferritin. Gene expression patterns supported significance demonstrated enrichment transcripts related stems. Distinct among genes observed relation content indicating tissue‐specific regulatory mechanisms governing accumulation. Secondary plays role storage A. , while may transiently for seed production. Future research will address different signalling pathways PZ.

Human nutrition is inherently associated with the cultivation of vegetables, grains, and fruits, underscoring critical need to understand manipulate balance between vegetative reproductive development in plants. Despite vast diversity within plant kingdom, these developmental processes share conserved interconnected pathways among angiosperms, predominantly involving age, vernalization, gibberellin, temperature, photoperiod, autonomous pathways. These interact environmental cues orchestrate transition from growth stages. Related this, there are two key genes belonging same Phosphatidylethanolamine-binding proteins family (PEBP), FLOWERING LOCUS T (FT) TERMINAL FLOWER 1 (TFL1), which activate repress floral initiation, respectively, different species. They compete for transcription factors such as D (FD) 14-3-3 form activation complexes (FAC) repression (FRC). The FT/TFL1 mechanism plays a pivotal role meristem differentiation, determining outcomes determinate or indeterminate. This review aims explore roles FT TFL1 architecture induction annual perennial species, together their interactions hormones. In this context, we propose that can be modulated by response and/or regulators (PGRs), emerge potential tools mitigating adverse effects changes on processes. Thus, understanding mechanisms crucial address challenges agricultural practices, especially face climate change.

Abstract Sea-level rise will increase salt intrusion and flood risk in low-lying lands. In the long run, these lands change into seawater-influenced landscapes, as is already happening several coastal areas around globe. While conventional agriculture may no longer bear fruit such sea-landscapes, seagrass species Zostera marina , “sea-rice,” potentially yields 3–7% of global rice production, with added benefit zero-carbon emissions. Culture Z. does not require freshwater, fertilizer or pesticides. Development implementation mariculture open new avenues for collaborative efforts multiple disciplines agronomy, engineering social sciences. From start, domestication, design landscape planning should aim at optimal balance between ecosystem goods (grains, straw seafood) services (coastal protection, carbon nitrogen sequestration, filtering pathogens pollutants, biodiversity) this potential crop, while respecting restoring wild meadows.

Abstract Plants serve as reservoirs for vital micronutrients, including iron, which they store in bioavailable forms to support growth subsequent seasons. The perennial life style is preponderant nature. Annual species allocate iron towards their seeds. However, our understanding of homeostasis plants remains limited. Arabis alpina a model organism. Its perenniating branches undergo secondary where carbon-rich macromolecules. In this study, we investigated the and annual stem zones (PZ, AZ) A. . We found that both, wild-type Pajares (Paj) perpetual flowering 1 mutant accumulated at various developmental stages PZ well AZ. Notably, levels were be approximately two-fold higher than those AZ, underscoring PZ’s enhanced capacity storage, irrespective status. Iron was predominantly located within plastid-bound ferritin, providing insight into its storage mechanism. Furthermore, gene expression analyses supported significance ferritin demonstrated an enrichment transcripts related stems. Distinct patterns among genes observed relation contents indicating tissue-specific regulatory mechanisms governing accumulation. These findings collectively emphasize critical function important site plants, suggesting thatfuture research should further explore nuances signaling plants. Highlight ‐ accumulates zone, form there. Transcripts are enriched expressed zones, yet accumulation correlates with different patterns.
