Tubby-like proteins (TLPs) are found in a broad range of multicellular organisms. In mammals, genetic mutation of tubby or other TLPs can result in certain disease phenotypes related to animal specific characters: obesity, retinal degeneration, hearing loss, et al. Plants also harbor a large number
All apple cultivars harbor the trait called self-incompatibility. Self-incompatibility represents that the pistils of the flowers are not successfully fertilized with own, the same cultivar's pollens. Compatibility or incompatibility of apple flowers are determined by S alleles. For example,
The immunomodulatory effects of Malus halliana flower polysaccharide (MHFP) were investigated in this paper. The model of immunosuppressive mice was established by cyclophosphamide, which was treated with different dosages of MHFP (600, 400, and 200 mg/kg·d-1). The results showed
Watercore is a so-called physiological disorder of apple (Malus domestica L.) that commonly occurs in several well-known cultivars. It is associated with a rapid softening of the flesh that causes a marked changed in flavor and texture. In Asia, apples with watercore are preferred and
BACKGROUND
Apple fruitlet abscission is induced by dominance, a process in which hormones such as auxin, cytokinins and strigolactone play a pivotal role. The response to these hormones is controlled by transcription regulators such as Aux/IAA and ARR, whereas auxin transport is controlled by influx
The effect of fish gelatin and chitosan coatings on the physicochemical characteristics of fresh-cut apples (Malus pumila Mill.), stored at 5 °C and 22 °C, was investigated. Chitosan provided an effective control for microbial growth, maintained firmness during 4 days of storage at room
ABSTRACT A polyvalent nested reverse transcription-polymerase chain reaction (RT-PCR) test using degenerate primers containing inosine (polyvalent degenerate oligonucleotides [PDO]) was developed for filamentous fruit tree viruses belonging to the genera Trichovirus, Capillovirus, and Foveavirus.
Eleven distinct families of resistance gene analogs (RGAs) with the characteristic nucleotide-binding sequence (NBS) were identified in two wild apple species, Malus prunifolia and M. baccata, and two cultivated apple cultivars, M. domestica cv. Fuji and M. domestica cv. Hong-ok, using PCR
Apple ( Malus x domestica Borkh.) sequences sharing homology with known resistance genes were cloned using a PCR-based approach with degenerate oligonucleotide primers designed on conserved regions of the nucleotide-binding site (NBS). Sequence analysis of the amplified fragments indicated the
Cystic Fibrosis (CF) is the most diffuse autosomal recessive genetic disease affecting Caucasians. A persistent recruitment of neutrophils in the bronchi of CF patients contributes to exacerbate the airway tissue damage, suggesting that modulation of chemokine expression may be an important target
Several plant disease resistance gene (R-gene) classes have been identified on the basis of specific conserved functional domains. Cloning of disease-resistance apple genes would be useful for breeding programs and for studying resistance mechanisms. We used a PCR approach with degenerate primers
Organisms make the best of their mother's oviposition choices and utilize specific feeding options that meet energetic requirements and cope with environmental constraints. This is particularly true for leaf-miner insects that develop enclosed in the two epidermis layers of a single leaf for their
The conserved domains of reverse transcriptase (RT) genes of Ty1-copia and Ty3-gypsy groups of long terminal repeat (LTR) retrotransposons were isolated from the Malus domestica genome using degenerate oligonucleotide primers. Sequence analysis showed that 45% of Ty1-copia and 63% of Ty3-gypsy RT
Increased production of terpenes and many other aroma-related volatiles occurs with the onset of ripening in apple ( Malus domestica Borkh.) fruit. The gaseous plant hormone ethylene plays a key role in the induction of volatile synthesis, but the mechanism is not yet understood. Using a degenerate
Apple mosaic virus (ApMV) has been reported to naturally infect a number of hosts in the Rosaceae family including Rosa spp., Malus spp., and Rubus spp. etc., as well as several hosts such as Humulus spp. and Betula spp. in other plant families (2), but has not been reported to naturally infect
