Brassinolide (BL) mediates various physiological processes and improves plant tolerance to abiotic stresses. However, the effects mechanism of exogenous BL on salt apple seedlings remain unclear. Herein, we investigated role in stress response Malus hupehensis Rehd., a widely grown rootstock. Salt-stressed showed significant decline chlorophyll content photosynthetic rate, application 0.2 mg/L alleviated maintained capacity. Exogenous can strengthen activities superoxide dismutase catalase...
Salinity-alkalinity stress can remarkably affect the growth and yield of apple. Strigolactone (SL) is a class carotenoid-derived compounds that functions in tolerance. However, effects mechanism exogenous SL on salinity-alkalinity tolerance apple seedlings remain unclear. Here, we assessed effect response Malus hupehensis seedlings. Results showed treatment with 100 μM analog (GR24) could effectively alleviate higher chlorophyll content photosynthetic rate than without GR24 treatment. The...
Soil acidification in apple (Malus domestica) orchards results the release of rhizotoxic aluminum ions (Al3+) into soil. Melatonin (MT) participates plant responses to abiotic stress; however, its role AlCl3 stress remains unknown. In this study, root application MT (1 μM) substantially alleviated (300 Pingyi Tiancha hupehensis), which was reflected by higher fresh and dry weight, increased photosynthetic capacity, longer more roots compared with plants that did not receive treatment....
Large amounts of potash fertilizer are often applied to apple (Malus domestica) orchards enhance fruit quality and yields, but this treatment aggravates KCl-based salinity stress. Melatonin (MT) is involved in a variety abiotic stress responses plants. However, its role KCl tolerance still unknown. In the present study, we determined that an appropriate concentration (100 μm) MT significantly alleviated Malus hupehensis by enhancing K+ efflux out cells compartmentalizing vacuoles....
SUMMARY Poor management and excess fertilization of apple ( Malus domestica Borkh.) orchards are causing increasingly serious soil acidification, resulting in Al toxicity direct poisoning roots. Strigolactones (SLs) reported to be involved plant responses abiotic stress, but their role mechanism under AlCl 3 stress remain unknown. Here, we found that applying 1 μ m GR24 (an SL analoge) significantly alleviated M26 rootstock, mainly by blocking the movement through cell wall vacuolar...
Dwarfing rootstocks and dwarf cultivars are urgently needed for modern pear cultivation. However, germplasm resources dwarfing limited, the underlying mechanisms remain unclear. We previously showed that dwarfism in is controlled by single dominant gene PcDw (Dwarf). report here expression of PcAGP7-1 (ARABINOGALACTAN PROTEIN 7-1), a key candidate PcDw, significantly higher dwarf-type plants because mutation an E-box promoter. Electrophoretic mobility shift assays transient infiltration...
Δ1-Pyrroline-5-carboxylate synthetase (P5CS) acts as the rate-limiting enzyme in biosynthesis of proline plants. Although P5CS plays an essential role plant responses to environmental stresses, its biological functions remain largely unclear pear (Pyrus betulifolia). In present study, 11 putative P5CSs (PbP5CSs) were identified by comprehensive bioinformatics analysis and classified into five subfamilies. Segmental tandem duplications contributed expansion evolution PbP5CS gene family....
Abstract Background The steroidal hormones brassinosteroids (BRs) play important roles in plant growth and development. pathway genes involved BR biosynthesis have been identified primarily model plants like Arabidopsis , but little is known about woody fruits such as pear. Results In this study, we found that applying exogenous brassinolide (BL) could significantly increase the stem rooting ability of Pyrus ussuriensis . PcDWF1 which had a lower level expression dwarf-type pear than...
Dwarf tree architecture is an important agronomic trait for modern fruit breeding and cultivation. The dwarf growth habit of pear (Pyrus communis L.), inherited from the cultivar 'Nain Vert', controlled by a single dominant gene PcDw. To fine map PcDw locus at higher resolution, 14 primer pairs recently reported simple sequence repeat (SSR) markers mapped to top region linkage group 16 (LG16) in apple maps, as well 43 50 new based on European genome sequences identifying SSR nucleotide...
Dwarfism is an important trait which closely related to the efficiency of fruit orchard management and production. However, dwarfing cannot be widely applied in cultivation pears, especially Asian pears. Developing varieties with dwarf characteristics a goal paramount importance pear breeding. In present study, phenotype pears (DPPs) arborescent (APPs) were obtained from offspring cross between 'Aiyuxiang' 'Cuiguan' cultivars, exhibited dwarfed statures, respectively. When compared APPs,...
Abstract Background: Apple is among the most widely cultivated perennial fruit crops worldwide. It sensitive to salt stress, which seriously affects growth and productivity of apple trees by destroying homeostasis Na + K . Previous studies focused on molecular mechanism underlying NaCl stress. However, signaling transduction under KCl stress has not been thoroughly studied. Results: We comprehensively analyzed tolerance Malus hupehensis Rehd., a used rootstock in orchards, using RNA-Seq....
