Degenerate oligonucleotide primers, designed based on conserved regions of several serine-threonine kinases (STK) previously cloned in tomato and Arabidopsis, were used to isolate STK candidates in wild and cultivated strawberries. Seven distinct classes of STKs were identified from three related
Degenerate oligonucleotide primers, designed based on conserved regions of Nucleotide Binding Site (NBS) domains from previously cloned plant resistance genes, were used to isolate Resistance Gene Analogues (RGAs) from wild and cultivated strawberries. Seven distinct families of RGAs of the NBS-LRR
A cDNA (Cel1) encoding an endo-1,4-beta-glucanase (EGase) was isolated from ripe fruit of strawberry (Fragaria x ananassa). The deduced protein of 496 amino acids contains a presumptive signal sequence, a common feature of cell wall-localized EGases, and one potential N-glycosylation site. Southern-
Strawberry mottle virus (SMoV) is probably the most important virus to infect strawberry (Fragaria spp.). All species of strawberry are susceptible to SMoV, resulting in severe losses both in fruit and runner yield. However, due to the absence of definitive symptoms in commercial varieties, the only
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
Phospholipase D alpha (PLD, EC 3.1.4.4)) is a key enzyme involved in membrane deterioration that occurs during fruit ripening and senescence. The biochemical and molecular characteristics of PLD was studied in strawberry (Fragaria ananassa Duch) fruits, which are non-climacteric fruits. PLD activity
Tissue softening accompanies the ripening of many fruit and initiates the processes of irreversible deterioration. Expansins are plant cell wall proteins proposed to disrupt hydrogen bonds within the cell wall polymer matrix. Expression of specific expansin genes has been observed in tomato
Several natural antimicrobial compounds derived from essential oils of plants were investigated for their efficacies in inhibiting decay and extending the shelf life of strawberries (Fragaria x ananassas Duch.). The severity of decay in strawberries stored at 10 degrees C was significantly reduced
Among the downstream targets of calcium in plants, calcium-dependent protein kinases (CDPKs) form an interesting class of kinases which are activated by calcium binding. They have been implicated in a diverse array of responses to hormonal and environmental stimuli. In order to dissect the role of
Ramet propagation in strawberry (Fragaria × ananassa) is the most effective way in production. However, the lack of systematically phenotypic observations and high-throughput methods limits our ability to analyze the key factors regulating the heterogeneity in strawberry stolon In the process of attempting to identify the rose rosette agent, double-stranded RNA was isolated from several symptomatic Rosa multiflora plants from northwestern Arkansas. The pattern of the dsRNA bands differed among the five samples used in this study, suggesting the presence of several viruses.
