Effect of thermal acclimation on the tolerance of the peach fruit fly (Bactrocera zonata: Tephritidae) to heat and cold stress
<p>The effect of thermal acclimation on cold and heat tolerance of the peach fruit fly (<em>Bactrocera zonata</em>) was studied. Males and females were acclimated at 20, 25 and 30°C for up to 19 days following adult emergence. The critical thermal minimum (CT<sub>min</sub>) and maximum (CT<sub>max</sub>) were subsequently recorded as well adult survival following acute exposure to chilling (0 or -3°C for 2 hours). Additionally, the survival of pupae subjected for two hours to temperatures ranging from -12°C to 5°C was determined.</p> <p>The raw data collected during this study is available in the provided data file.</p>

Identification and characterization of QTLs for fruit quality traits in peach through a multi-family approach
Background <p>Fruit quality traits have a significant effect on consumer acceptance and subsequently on peach (<i>Prunus persica</i> (L.) Batsch) consumption. Determining the genetic bases of key fruit quality traits is essential for the industry to improve fruit quality and increase consumption. Pedigree-based analysis across multiple peach pedigrees can identify the genomic basis of complex traits for direct implementation in marker-assisted selection. This strategy provides breeders with better-informed decisions and improves selection efficiency and, subsequently, saves resources and time.</p> Results <p>Phenotypic data of seven F<sub>1</sub> low to medium chill full-sib families were collected over 2 years at two locations and genotyped using the 9 K SNP Illumina array. One major QTL for fruit blush was found on linkage group 4 (LG4) at 40–46 cM that explained from 20 to 32% of the total phenotypic variance and showed three QTL alleles of different effects. For soluble solids concentration (SSC), one QTL was mapped on LG5 at 60-72 cM and explained from 17 to 39% of the phenotypic variance. A major QTL for titratable acidity (TA) co-localized with the major locus for low-acid fruit (<i>D</i>-locus). It was mapped at the proximal end of LG5 and explained 35 to 80% of the phenotypic variance. The new QTL for TA on the distal end of LG5 explained 14 to 22% of the phenotypic variance. This QTL co-localized with the QTL for SSC and affected TA only when the first QTL is homozygous for high acidity (epistasis). Haplotype analyses revealed SNP haplotypes and predictive SNP marker(s) associated with desired QTL alleles.</p> Conclusions <p>A multi-family-based QTL discovery approach enhanced the ability to discover a new TA QTL at the distal end of LG5 and validated other QTLs which were reported in previous studies. Haplotype characterization of the mapped QTLs distinguishes this work from the previous QTL studies. Identified predictive SNPs and their original sources will facilitate the selection of parents and/or seedlings that have desired QTL alleles. Our findings will help peach breeders develop new predictive, DNA-based molecular marker tests for routine use in marker-assisted breeding.</p>

MADS2 regulates priming defence in postharvest peach through combined salicylic acid and abscisic acid signaling
<p>MADS-box genes play well-documented roles in plant development, but relatively little has been recorded regarding their involvement in the defence response. Herein, the treatment of peach fruit with BABA activated resistance against Rhizopus stolonifer, leading to a significant delay in the symptomatic appearance of Rhizopus rot disease. This protection was greatly potent in R. stolonifer-inoculated peaches and equipped the intertwined defence response containing H2O2 burst, ABA accumulation and callose deposition. Moreover, nucleus-localized PpMADS2 was identified as a PpNPR1 interacting partner via cDNA library screening. Y2H, LCI and co-IP assays further verified the interaction between PpNPR1 and PpMADS2. The DNA binding activity of PpNPR1 conferred by the PpNPR1-PpMADS2 complex was required for the transcription of SA-dependent PR and ABA-inducible PpCalS genes to gain the augmented BABA-IR, in which the PpMAPK1-induced posttranslational modification of PpMADS2 simultaneously was involved. Accordingly, PpMADS2 overexpression potentiated the transcription of a group of PR genes and fungal resistance in transgenic Arabidopsis. Conversely, mads2 knockout lines showed high sensitivity to fungal pathogen. Therefore, the results indicate that PpMADS2 positively participates in the BABA-elicited defence in peaches through the collaboration of SA-dependent NPR1 activation and ABA-signaling callose accumulation, which is also related to the posttranslational modification of PpMADS2 by PpMAPK1 for signal amplification.</p>

Tea seed meal application promoted microbial community diversity in the soil of peach orchard
<p><span>Soil microbes are indispensable in agricultural production, and they respond differently to different fertilization regimes. However, there is limited understating of microbial composition and function responses to an organic fertilizer tea seed meal (TSM) and conventional fertilizer. Here we first reported the change rules and functions of soil microbial community in peach orchard soil after application of compound fertilizer plus urea (CFU) and different amounts (1.25, 2.50, 3.75 and 5.00 kg) of TSM. Compared to CFU, the application of 1.25, 2.50 and 3.75 kg TSM significantly decreased the Chao1 index of bacterial community in peach orchard soil. The Shannon index of bacterial and fungal communities in 2.50 kg TSM treatment was significantly higher than that in CFU. Beta diversity analysis of bacteria and fungi (based on Bray-Curtis matrix and OTUs level) revealed significant structural differences among all five experimental groups (ANOSIM, bacteria: R= 0.665, p = 0.001; fungi: R= 0.996, p = 0.001). The TSM treatments significantly decreased the relative abundances of potentially unfriendly bacteria (<em>Acidothermus</em>, <em>Acidicaldus</em>, </span><span><em>Sphingomonas</em>,</span><span> <em>Candidatus</em> <em>Koribacter</em> and <em>Candidatus</em> <em>Solibacter</em>) and fungi (<em>Fusarium</em>), and significantly increased the relative abundances of potentially beneficial fungi (<em>Trechispora</em>, <em>Sagenomella</em>, <em>Penicillium</em>, <em>Acaulium</em> <em>caviariforme</em>, <em>Leucoagaricus</em> and <em>Chlorophyllum</em>) compared with CFU. These changes were more obvious when the application amount of TSM was 2.50 kg. This study provides insights into the potential of application of TSM as an organic fertilizer in agricultural production.</span></p>
Fitness costs and oviposition choice of C. nenuphar on blueberry and peach
<p>In phytophagous insects, adult attraction and oviposition preference for a host plant is often positively correlated with their immature performance; however, little is known how this preference-performance relationship changes within insect populations utilizing different host plants. Here, we investigated differences in the preference and performance of two populations of a native North American frugivorous insect pest, the plum curculio (Conotrachelus nenuphar) ‒ one that utilizes peaches and another that utilizes blueberries as hosts ‒ in the Mid-Atlantic United States. For this, we collected C. nenuphar adult populations from peach and blueberry farms and found that they exhibited a clear preference for the odors of, as well as an ovipositional preference for, the hosts they were collected from, laying 67-83% of their eggs in their respective natal hosts. To measure C. nenuphar larval performance, a fitness index was calculated using data on larval weights, development, and survival rate from egg to fourth instars when reared on the parent's natal and novel hosts. Larvae of C. nenuphar adults collected from peach had high fitness on peach but low fitness when reared on blueberry. In contrast, larvae from C. nenuphar adults collected in blueberry had high fitness regardless of the host they were reared on. In this study, we show that utilizing a novel host such as blueberry incurs a fitness cost for C. nenuphar from peaches, but this cost was not observed for C. nenuphar from blueberries, indicating that the preference-performance relationship depends on the particular insect population-host plant association.</p>
