The use of mulching, compost, and their interaction on organic residue (OR) decomposition rate (k), time decay, primming effect, soil organisms’ community composition was tested in a 16-year P. pyrifolia field experiment conducted from January 2020 to June 2021. A 2 × factorial design used with compost mulching as the two factors within four blocks. OR characterized by using litter bags differe...
The differences between stylar protein of the Japanese pear (Pyrus pyrifolia (Burm.f.)) cultivars ‘Kosui’ (SS) and ‘Kikusui’ (SS) were compared by two-dimensional difference gel electrophoresis (2-D DIGE), and were labelled and visualized with different fluorescent dyes (IC3-OSu, IC5-OSu) on a single 2-D gel. The individual different expressed proteins spots were subjected to identification. Th...
Using an F1 population from a cross between Japanese pear (Pyrus pyrifolia Nakai) cultivars 'Akiakari' and 'Taihaku', we performed quantitative trait locus (QTL) analysis of seven fruit traits (harvest time, fruit skin color, flesh firmness, fruit weight, acid content, total soluble solids content, and preharvest fruit drop). The constructed simple sequence repeat-based genetic linkage map of '...
Pear black spot (PBS) disease, which is caused by Alternaria alternata (Aa), is one of the most serious diseases affecting sand pear (Pyrus pyrifolia Nakai) cultivation worldwide. To investigate the defense mechanisms of sand pear in response to Aa, the transcriptome of a sand pear germplasm with differential resistance to Aa was analyzed using Illumina paired-end sequencing. Four libraries der...
Although the potential of marker-assisted selection (MAS) in fruit tree breeding has been reported, bi-parental QTL mapping before MAS has hindered the introduction of MAS to fruit tree breeding programs. Genome-wide association studies (GWAS) are an alternative to bi-parental QTL mapping in long-lived perennials. Selection based on genomic predictions of breeding values (genomic selection: GS)...
مناطق غیرکدکننده برای ارزیابی گروهبندیهای فیلوژن در جنس pyrus بسیار قابل استفاده است زیرا این مناطق کمتر عملکردی بوده و بنابراین تنوع آنها تحت تأثیر انتخاب خنثی است. در این پژوهش، روش توالیهای چندشکل تکثیر شدۀ شکسته شده (cleaved amplified polymorphic sequence: caps) برای تجزیۀ سه ناحیۀ بسیار متغیر در نواحی بینژنی dna کلروپلاست در 73 رقم بومی و ژنوتیپ وحشی گلابی ایرانی و اروپایی (pyrus co...
