The high mountain forests on Earth are characterized by sharp environmental heterogeneity, species endemism, and unique phenotypic adaptations. Yet, global warming is jeopardizing this ecosystem as no other some may have nowhere to go beyond the mountain’s summits. One of most human-endangered high-elevation ecosystems Polylepis forest. Despite its vulnerability, forecasting climate reactions in distinctive forest type remains a formidable challenge. Therefore, study, we modeled change responses allopatric sericea P. quadrijuga (Rosaceae) northern Andes. analysis took into account VIF-prioritized bioclimatic variables for near-to-present future (2081–2100 MPI-ESM1-2-HR) conditions.

Terminal heat stress severely affects field pea production in tropical climates. Identifying and characterizing marker-trait(s) remain vital for breeding heat-tolerant cultivars of pea. Field genotypes are highly variable plant stature; however, the significance stature yield stability under high-temperature conditions is not yet well understood. The study aimed to investigate sensitivity toward sustainability environments. A panel 150 diverse with statures [dwarf (<50 cm), semi-dwarf (50-80 medium-tall (80-150 cm)] were grown late sowing-induced environments two consecutive years (2017-2019). During first year experiment, sown crops (15 30 days) exposed high-temperatures at flowering (+3.5 +8.1 °C) grain-filling (+3.3 +6.1 over timely crops. Likewise, elevated temperature during (+3.7 +5.2 grain filling (+5.4 +9.9 recorded late-sown (delayed by 27 54 next year. Medium-tall had longer duration (7-10%), higher pod-bearing nodes (8-18%) (22-55%), lower losses (13-18%) dwarf Significant associations height yield, loss, heat-susceptibility index suggested tolerance capacity tall-type plants compared types. GGEbiplot analysis revealed that all medium (mean = 108 while heat-susceptible mostly stature. Hence, better adaptability Henceforth, approach may be designed embracing backgrounds develop climate resilient cultivars.

Abstract Genomic characterization of ex situ plant collections optimizes the utilization genetic resources by identifying redundancies among accessions, capturing cryptic variation, establishing reference collections, and ultimately assisting pre-breeding breeding efforts. Yet, integration evolutionary genomic analyses is often lacking when studying biodiversity crop gene pools. Such case in avocado, Persea americana Mill., an iconic American fruit tree that has seen unprecedented expansion worldwide because its nutritional properties. However, given a very restricted number commercial clones, avocado plantations are becoming more vulnerable to diseases climate change. Therefore, exploring new sources novelty diversity beyond varieties derived from traditional pools Mexico Central America imperative. To fill this gap, we aimed characterize Colombian trees. Specifically, constructed reduced representation libraries genotype sequencing 144 accessions National genebank 240 materials local orchards northwest Andes. We merged resulting reads with available sequences genotypes known groups (also named as races), Mexican, Guatemalan, West Indian, discover 4931 SNPs. then analyzed population structure phylogenetic diversity, reconstructed scenarios, possibly leading germplasm. detected demographic stratification despite evidence intergroup flow. Besides classical three groups, found exclusive group possible substructure related geographical origin (Andean Caribbean). Phylogenetic ABC modeling suggested evolved Pleistocene before human agriculture started, closest relative recognized races would be Indian group. conclude South offers source allelic capable boosting strategies select rootstock candidates well adapted specific eco-geographical regions Colombia abroad.
