Knowledge about the degree of genetic diversity and population structure is crucial as it facilitates novel variations that can be used in breeding programs. Similarly, genome-wide association studies (GWAS) reveal candidate genes controlling traits interest. Sugar beet a major industrial crops worldwide, generating 20% world's total sugar production. In this work, using genotyping by sequencing (GBS)-derived SNP silicoDArT markers, we present new insights into level an international germplasm (94 accessions from 16 countries). We also performed GWAS to identify for agriculturally-relevant traits. After applying various filtering criteria, 4,609 high-quality non-redundant SNPs 6,950 markers were analyses. Calculation indices (e.g., mean gene diversity: 0.31, MAF: 0.22) (mean 0.21, 0.12) data sets revealed existence good conserved diversity.

For a Colorful Life: Recent Advances in Anthocyanin Biosynthesis during Leaf Senescence

Biology, Год журнала: 2024, Номер 13(5), С. 329 - 329

Опубликована: Май 9, 2024

Leaf senescence is the last stage of leaf development, and it accompanied by a color change. In some species, anthocyanins are accumulated during senescence, which vital indicators for both ornamental commercial value. Therefore, essential to understand molecular mechanism anthocyanin accumulation would provide new insight into autumn coloration breeding more colorful plants. Anthocyanin surprisingly complex process, significant advances have been made in past decades. this review, we focused on senescence. We emphatically discussed several networks linked genetic, hormonal, environmental, nutritional factors regulating This paper aims regulatory model put forward prospects future development.

NAC Transcription Factor PpNAP4 Promotes Chlorophyll Degradation and Anthocyanin Synthesis in the Skin of Peach Fruit

Journal of Agricultural and Food Chemistry, Год журнала: 2024, Номер 72(36), С. 19826 - 19837

Опубликована: Авг. 30, 2024

Chlorophyll (Chl) catabolism and anthocyanin synthesis play pivotal roles in determining the final skin color of fruits during maturation. However, peach (Prunus persica) fruit, regulatory mechanism governing color, especially Chl catabolism, remains largely elusive. In this study, we identified ten catabolic genes (CCGs), with PpSGR emerging as a key regulator degradation peaches. Furthermore, NAC-like, activated by AP3/P1 (NAP) transcription factor (TF), PpNAP4, was positive modulator breakdown. PpNAP4 induced expression other CCGs, including PpPPH, PpPAO, PpTIC55–2, directly binding to their promoters. Overexpression resulted heightened these accelerated degradation. Notably, also positively regulated PpANS PpMYB10.1, one structural gene core transcriptional synthesis, thereby contributing fruit coloration. summary, our findings elucidate that serves orchestrating accumulation through direct activation multiple CCGs related genes.

Abstract The flower bud differentiation plays a crucial role in cherry yield and quality. In preliminary study, we revealed the promotion of spermidine (Spd) However, molecular mechanism underlying Spd regulating remains unclear. To address this research gap, cloned CpSPDS2 , gene that encodes synthase is highly expressed whole flowers pistils Chinese (cv. ‘Manaohong’). Furthermore, an overexpression vector with was constructed to transform tobacco plants. findings demonstrated transgenic lines exhibited higher content, earlier flowering time by 6 d, more lateral buds than wild‐type lines. Additionally, yeast one‐hybrid assays two‐luciferase experiments confirmed R2R3‐MYB transcription factor (CpMYB44) directly binds activates promoter transcription. It indicated CpMYB44 promotes accumulation via expression, thus accelerating growth. This provides basis for resolving involved differentiation.

PbNAC3 coordinates AsA generation and ABA biosynthesis to improve salt tolerance in pear

The Plant Journal, Год журнала: 2025, Номер 122(2)

Опубликована: Апрель 1, 2025

SUMMARY In plants, dehydroascorbate reductase (DHAR) is one of the key enzymes in AsA generation during AsA‐GSH cycle, which helps maintain normal metabolic level AsA. However, molecular mechanism DHAR's response to salt stress still unknown. Our experiments show a ping‐pong mechanism, DHA combined with free DHAR, and DHAR GSH form sulfenylation promote stress. This inhibited by H 2 O ‐mediated modification. The overexpression PbDHAR3 pear callus Arabidopsis plants alleviated salt‐induced damage, while its silencing decreased tolerance Pyrus betulaefolia . PbNAC3 can activate expression directly binding promoter. improved tolerance, it reduced P. betulaefolia. Overexpression able adjust trade‐off between plant growth Higher levels NCEDs or PYLs , higher ABA content were observed under treatment. Further demonstrate that activates PbNCED5 through interaction cis ‐regulatory elements. Overall, our results plays critical role targeting promoters promoting biosynthesis. study will deepen understanding mechanisms underlying trade‐offs assist development stress‐resistant, high‐yield crops.

Citrus, a globally vital economic crop, faces severe challenges due to extreme climatic conditions and diseases/pests attack. Poncirus trifoliata is closely related citrus shows unique cold tolerance, making it crucial material for unraveling genes involved in tolerance. NAC (NAM, ATAF1/2, CUC2) transcription factors play important roles plant growth, development, stress responses. However, their evolution patterns gene functions remain poorly studied. This study aims elucidate the genomic characteristics of P. trifoliata, analyze expression conduct functional validation under stress. Genome-wide analysis identified 135 PtrNAC with non-random chromosomal distribution, including 20 clusters. 57.78% are located chromosomes 3, 4 5. Gene duplication revealed that proximal tandem duplications as primary expansion mechanisms, repeats specifically driving lineages (subfamilies IV, V, VII). Collinearity showed 24.44% were retained homologous regions, Ka/Ks ratio further confirmed purifying selection dominated evolutionary process. Transcriptome landscapes Pt5g024390 (PtrNAC2) was induced greatest degree Meanwhile, level PtrNAC2 tetraploid more than two folds higher compared diploid counterpart presence Virus-induced silencing led significantly enhanced implying plays negative role regulation systematically elucidated global distribution trifoliata. In addition, exhibit adaptive driven by duplications. The identification PtrNAC2, regulator tolerance provides valuable insights into unravelling potential candidates engineering citrus.
