Published: March 14, 2025

Sugarcane is primarily propagated for large-scale agricultural production through vegetative reproduction by planting stem cuttings. Development of sprout and sett root from the cuttings essential sugarcane plant to adapt field environment. We observed asynchronous development during sprouting in two sibling cultivars sharing same parent cross breeding: axillary buds cultivar ZZ2 (ZZ2B) earlier, while roots ZZ9 (ZZ9R) emerge sooner. Comparison architecture, soluble sugar content, hormone levels gene expression profiles sprouting. found that has a lower cortex thickness ratio higher vascular cylinder ratio. also identified significant differences sugars, 3-Indolebutyric acid (IBA), N6-isopentenyladenosine (IPA), cis-Zeatin (cZ), Abscisic Acid (ABA), Gibberellin A3 (GA3), A7 (GA7), (±)-Jasmonic (JA), N-((-)-jasmonoyl)-Sisoleucine (JA-Ile) between these cultivars. In addition, we differentially expressed genes transcriptomic analysis discovered, via GO KEGG enrichment analyses, negative regulation external stimulus response key preference early bud The Twin-arginine translocation complex (Tat) significantly influences ZZ9's emergence. Furthermore, weighted co-expression network (WGCNA) revealed specific metabolic processes seed coat mucilage uniquely determine buds. These findings provide theoretical foundation new perspective understand production, offering novel insights breeding high-quality varieties.

Intraspecific plant-soil feedbacks alter root traits in a perennial grass

Published: March 14, 2025

Drought is a common stressor faced by plants and their associated microbiomes. Projected climate data point toward an increase in the severity frequency of extreme precipitation events, such as drought. Previous research has shown that long-term exposure to drought can shape plants' genomes, resulting genetic variation for tolerance. We hypothesized these changes also affect patterns microbial colonization rhizosphere, potentially feeding back influence plant responses. Here, we tested 33 rhizosphere soils conditioned genotypes Tripsacum dactyloides (eastern gamagrass) originated from native populations across gradient southern plains United States. used inocula fully factorial experiment test responses conspecific differentially under or well-watered conditions. Variation aboveground traits shoot length, weight, root-to-shoot ratios was primarily explained watering treatment.

The differential intraspecies plant-soil feedback dynamics driven local adaptation will key understanding future rapidly shifting climates, restoration projects agricultural systems.

Root Phenotyping: A Contribution to Understanding Drought Stress Resilience in Grain Legumes

Agronomy, Journal Year: 2025, Volume and Issue: 15(4), P. 798 - 798

Published: March 24, 2025

Global climate change predictions point to an increase in the frequency of droughts and floods, which are a huge challenge food production. During crop evolution, different mechanisms for drought resilience have emerged, studies suggest that roots can be important key understanding these mechanisms. However, knowledge is still scarce, being fundamental its exploitation. Plant-based protein, especially grain legume crops, will crucial meeting demand affordable healthy due their high protein content. In addition, legumes unique ability biological nitrogen fixation (BNF) through symbiosis with bacteria, contributes sustainable agriculture. The exploitation root phenotyping techniques step toward selecting more resilient genotypes. Different methodologies available phenotyping, including paper pouch approach, rhizotrons semi-hydroponic system. Additionally, imaging been employed assess traits.

Flash drought as possible contributor to seedling dieback in the endangered conifer Abies koreana

Physiologia Plantarum, Journal Year: 2025, Volume and Issue: 177(2)

Published: March 1, 2025

Abstract Tree species grown at high altitudes experience significantly greater stress than those lower altitudes. A notable example is Abies koreana , a conifer recently classified as endangered due to decline in normal seedling distribution within Korean natural forests. While several hypotheses have been proposed explain this phenomenon, the underlying causes remain unclear. Recent studies highlight that forest tree are increasingly vulnerable flash drought (FD) events. However, it still unknown whether intense FD event affects growth and of high‐altitude like . To address gap, we investigated effects on root carbon allocation, volatile biosynthesis, fatty acid modulation, genome‐wide modifications. Exposure three‐year‐old A. seedlings primarily disrupted leaf chlorophyll likely depletion water non‐structural carbohydrates (NSC) transport above‐ground parts. Additionally, caused severe morphological changes, including reductions collar diameter along with cortical senescence. These alterations linked transcriptomic variations, particularly mRNA decay repression genes coding for ribosomal proteins. Seedlings exposed also exhibited increased levels abscisic (ABA) poly‐unsaturated acids. The observed patterns molecular mechanisms FD‐treated differed from control mild (MD) treatments. findings suggest conditions trigger rapid reserve gene associated structural integrity, potentially leading mortality seedlings.
