Liriodendron chinense (Hemsl.) Sarg. (Magnoliales: Magnoliaceae), valued for its medicinal properties and timber as an ornamental plant, is now classified endangered species. Investigating how future climate-change scenarios might affect the potential geographic distribution of L. will provide a crucial scientific basis protection management strategies. The MaxEnt model was calibrated using ENMeval optimization package, then it coupled with ArcGIS 10.8 to forecast possible areas in China, utilizing elevation data, bioclimatic factors, human footprint environmental variables. results indicate: (1) optimal parameters were set follows: FC = LQ, RM 0.5, demonstrated high predictive accuracy minimal overfitting; (2) total suitable habitat area geographical during current period estimated at 151.55 × 104 km2, predominantly located central, eastern, southwestern regions China; (3) minimum temperature coldest month (bio6), precipitation driest (bio14), quarter (bio17), warmest (bio18), (alt), (hf) are main variables determining chinense; (4) During from 2041 2060, under carbon emission SSP126, SSP245, SSP370, shows varying degrees increase compared period. However, highest concentration scenario SSP585, decreases some extent; (5) likely move towards higher latitudes elevations due changes climate.

SlWRKY51 regulates proline content to enhance chilling tolerance in tomato

Plant Cell & Environment, Год журнала: 2024, Номер 47(12), С. 5104 - 5114

Опубликована: Авг. 15, 2024

Chilling stress is a major environmental factor that significantly reduces crop production. To adapt to chilling stress, plants activate series of cellular responses and accumulate an array metabolites, particularly proline. Here, we report the transcription SlWRKY51 increases proline contents in tomato (Solanum lycopersicum) under stress. expression induced Knockdown or knockout led chilling-sensitive phenotypes, with lower photosynthetic capacity more reactive oxygen species (ROS) accumulation than wild type (WT). The were reduced knockdown lines perhaps explaining phenotypes these lines. D-1-pyrroline-5-carboxylate synthetase (P5CS), which catalyses rate-limiting step biosynthesis, encoded by two closely related P5CS genes (P5CS1 P5CS2). We demonstrate directly activates P5CS1 In addition, VQ (a class plant-specific proteins containing conserved motif FxxhVQxhTG) family member SlVQ10 physically interacts enhance its activation P5CS1. Our study reveals chilling-induced enhances tolerance promoting accumulation.

Caucasian clover (Trifolium ambiguum M.Bieb.) is a perennial legume known for its exceptional cold tolerance, commonly used in agriculture and ecosystems climates. Given the impact of climate change, enhancing adaptation crucial sustaining agricultural productivity. This study employs metabolomics, transcriptomics, Weighted Gene Co-expression Network Analysis (WGCNA) to investigate molecular mechanisms clover’s response low-temperature stress. Metabolomic analysis showed that stress triggered accumulation fatty acids, amino antioxidants, which are critical maintaining membrane stability antioxidant capacity, thus protecting plant from oxidative damage. Transcriptomic revealed significant upregulation genes involved adaptation, particularly those related defense, lipid repair, signal transduction, including ABA signaling pathway enzymes, thereby improving tolerance. WGCNA identified gene modules closely linked especially acid metabolism, repair. These function synergistically, with coordinated expression resistance. also investigated isoflavonoid biosynthesis under stress, highlighting role capacity Low-temperature induced key enzyme genes, such as Isoflavone Synthase (IFS) Isoflavone-7-O-Glucosyltransferase (IF7GT), promoting metabolite further plant’s adaptation. Overall, this offers novel insights into tolerance provides valuable theoretical support breeding cold-resistant crops

Cold tolerance in rapeseed is closely related to its growth, yield, and geographical distribution. However, the mechanisms underlying cold resistance remain unclear. This study aimed explore genes provide new insights into molecular of rapeseed. Rapeseed M98 (cold-sensitive line) D1 (cold-tolerant were used as parental lines. In their F2 population, 30 seedlings with lowest damage levels highest selected construct cold-tolerant cold-sensitive pools, respectively. The two pools lines analyzed using bulk segregant sequencing (BSA-seq). G’-value analysis indicated a single peak on Chromosome C09 candidate interval, which had 2.59 Mb segment 69 genes. Combined time-course weighted gene co-expression network analyses performed at seven time points reveal genetic basis two-parent response low temperatures. Twelve differentially expressed primarily involved plant identified. BSA-seq transcriptome revealed BnaC09G0354200ZS, BnaC09G0353200ZS, BnaC09G0356600ZS Quantitative real-time PCR validation was consistent RNA-seq. facilitates exploration

Peach is one of the most common stone fruit crops, but it also thermophilic. One main problems in peach cultivation frost up to −8 °C spring during pollen development, budding, and flowering. The adaptation plant low temperatures could be related activation antioxidant system under cold stress. aim this work was test hypothesis distinct mechanisms stress Prunus persica L. cultivars with various tolerances. difference between study previous ones that previously, only contrasting varieties (resistant sensitive) were studied. For first time, we studied effect on cold-resistant different degrees resistance, such as “Loadel” “Springold” (medium resistant) “Podarok Like” “Temisovskij” (highly resistant). experiment designed simulate effects short-term snaps, which are a occurrence February March south Crimea. A series tests conducted annual shoots frozen at −12 °C. activity gene expression two major enzymes, catalase peroxidase, by spectrophotometry RT-qPCR, respectively. showed these enzymes responded differently Catalase similarly all four varieties. After frost, there an increase (7-fold 3-fold Like”) decrease expression. In contrast catalase, peroxidase opposite response medium-tolerant highly tolerant cultivars. Peroxidase after exposure increased (1.5-fold “Temisovskij”), while decreased (1.5–2 fold “Loadel”, respectively). change opposite.

Genome-Wide Analysis of CPP Transcription Factor Family in Endangered Plant Phoebe bournei and Its Response to Adversity

Plants, Год журнала: 2025, Номер 14(5), С. 803 - 803

Опубликована: Март 5, 2025

The CPP gene family comprises transcription factor genes containing a conserved CRC domain, which is mainly involved in plant development and evolution. Although have been widely studied many plants, little known about them woody especially the endangered species Phoebe bournei (Hemsl.). In genome of bournei, we identified 11 PbCPP (PbCPP1-PbCPP11) distributed on four chromosomes, with large differences number amino acids. They encode both acidic alkaline proteins. A phylogenetic analysis showed that these can be divided into three subfamilies, A, B, C, contain seven, two, two genes, respectively. Through an interspecific collinearity analysis, homologous genes. promoter cis-acting element revealed PbCPPs variety elements respond to hormones, stress signals, light play role growth development, most (except PbCPP3 PbCPP8) MYB binding site regulate drought-induced responses, indicating they important drought resistance. An expression PbCPP4 was high roots stems lower leaves, whereas other low roots, stems, leaves. addition, six representative were detected using qRT-PCR. results show significant under abiotic conditions (drought, cold, salt), responses. This study preliminarily verified different great significance for understanding its mechanism adaptation.

PiERF1 regulates cold tolerance in Plumbago indica L. through ethylene signalling

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Янв. 11, 2025

Ethylene is a signalling factor that plays key role in the response of plants to abiotic stresses, such as cold stress. Recent studies have shown exogenous application 1-aminocyclopropane-1-carboxylate (ACC), an ethylene promoter, affects plant tolerance. The cold-responsive specific gene DREB crucial enhancing tolerance by activating several (COR) genes. However, how biosynthesis pathway regulates this thermophilic has yet be fully elucidated. In study, Plumbago indica L. was used example. Physiological experiments and transcriptomic analyses revealed stress treatment induced synthesis endogenous ACC regulated activator PiERF1, also activated PiDREB1A. Spray ACC-induced upregulation PiERF1 reduced P. decreased expression level PiDREB1A gene. These results indicate directly downstream initiates DREB‒COR regulate tolerance, resulting negative regulation plants.
