Theoretical and Applied Genetics, Год журнала: 2024, Номер 137(4)

Опубликована: Апрель 1, 2024

Abstract Key message This study revealed the identification of a novel gene, Zm00001d042906 , that regulates maize ear length by modulating lignin synthesis and reported molecular marker for selecting lines with elongated ears. Maize has garnered considerable attention due to its high correlation yield. In this study, six inbred significant importance in breeding were used as parents. The temperate line Ye107, characterized short ear, was crossed five tropical or subtropical featuring longer ears, creating multi-parent population displaying variations length.

Genetically correlated leaf tensile and morphological traits are driven by growing season length in a widespread perennial grass

American Journal of Botany, Год журнала: 2024, Номер 111(5)

Опубликована: Май 1, 2024

Leaf tensile resistance, a leaf's ability to withstand pulling forces, is an important determinant of plant ecological strategies. One potential driver leaf resistance growing season length. When seasons are long, strong leaves, which often require more time and resources construct than weak may be advantageous when short. Growing length other conditions also impact the morphological traits that underlie resistance.

Unveiling the role of the ERD15 gene in wheat's tolerance to combined drought and salinity stress: a meta‐analysis of QTL and RNA‐Seq data

Physiologia Plantarum, Год журнала: 2024, Номер 176(5)

Опубликована: Сен. 1, 2024

Abstract The coexistence of drought and salinity stresses in field conditions significantly hinders wheat ( Triticum aestivum L.) productivity. Understanding the molecular mechanisms governing response tolerance to these is crucial for developing resilient varieties. Our research, employing a combination meta‐QTL meta‐RNA‐Seq transcriptome analyses, has uncovered genome functional landscape salinity. We identified 118 meta‐QTLs (MQTLs) distributed across all 21 chromosomes, with ten designated as most promising. Additionally, we found 690 meta‐differentially expressed genes (mDEGs) shared between stress. Notably, our findings highlight Early Responsive Dehydration 15 ERD15 ) gene, located one promising MQTLs, key gene network , differentially contrasting genotypes under combined stress conditions, regulates water relations, photosynthetic activity, antioxidant ion homeostasis. These not only provide valuable insights into genetic underlying but also hold potential contribute development stress‐resilient

Local adaptation of switchgrass drives trait relations to yield and differential responses to climate and soil environments

GCB Bioenergy, Год журнала: 2023, Номер 15(5), С. 680 - 696

Abstract Switchgrass, a potential biofuel crop, is genetically diverse species with phenotypic plasticity enabling it to grow in range of environments. Two primary divergent ecotypes, uplands and lowlands, exhibit trait combinations representative acquisitive conservative growth allocation strategies, respectively. Whether these ecotypes respond differently various types environmental drivers remains unclear but crucial understanding how switchgrass varieties will climate change. We grew two upland, lowland, intermediate/hybrid cultivars at three sites along latitudinal gradient the central United States. Over 4‐year period, we measured plant functional traits biomass yields evaluated genotype‐by‐environment (G × E) interaction effects by analyzing responses soil variables. found substantial evidence G E interactions on yield, primarily due deviations response southern lowland cultivar Alamo, which produced more hotter drier environments relative other cultivars. While had highest for their were variable year‐to‐year compared cultivars, suggesting greater sensitivity perturbations. Models comparing principal components as explanatory variables revealed properties, especially nutrients, be most effective predicting yield. Also, positive correlations between yield traits, such high stem mass tiller height, became stronger lower latitudes where drier, regardless ecotype. Lowland however, showed predisposition traits. These results suggest trade‐offs that prioritize aboveground production are tightly associated hot, dry may specialized strategy Altogether, this research provides essential knowledge improving viability crop.

Abstract Compared to conventional crops, less is known about how genetic and environmental variability affect the yield quality of specialty crops like cranberry ( Vaccinium macrocarpon Ait.). Herein, we performed a multifaceted analysis six commercial beds planted Stevens cultivar. The included three with above‐average multiyear yields that were lower than average. We considered genotype, edaphic factors, plant nutrient content as driving variables fruit quality. found purity within raised odds obtaining over an 8‐year period. highest levels contamination (38%–75%) at low‐yield beds, where significant differences in observed between genotypes, beds. Across all focusing only on plots genetically confirmed be cultivar, also plot‐scale 2020 was significantly higher for two high‐yield suggesting other factors besides influenced bed‐scale yield.
