| effects of ferulic acid onglomus fasciculatum and associated effects on phosphorus uptake and growth of asparagus (asparagus officinalis l.). | the effect of ferulic acid, an allelochemical produced by asparagus, on hyphal elongation and colonization of asparagus byg. fasciculatum was studied. spore germination in vitro was not affected, but hyphal elongation decreased significantly with increasing ferulic acid concentration. in the greenhouse, mycorrhizal colonization of roots and growth of mycorrhizal asparagus decreased significantly with increasing ferulic acid concentration, while growth of nonmycorrhizal plants was not affected by ... | 1990 | 24263604 |
| survival of cultured cells and somatic embryos of asparagus officinalis cryopreserved by vitrification. | cultured cells and somatic embryos derived from the mesophyll tissue of asparagus (asparagus officinalis l.) were cryopreserved by vitrification. the vitrification solution (pvs) contains (w/v) 22% glycerol, 15% ethylene glycol, 15% propylene glycol and 7% dmso in murashige-skoog medium enriched with 0.5m sorbitol. after initial cryoprotection with sorbitol supplemented ms medium containing 12% ethylene glycol, cells or embryos were exposed stepwise to 85% pvs at 0°c. they were loaded into 0.5 m ... | 1989 | 24233367 |
| culture of asparagus protoplasts on porous polypropylene membrane. | a method of using a buoyant porous polypropylene membrane floated on liquid medium to culture protoplasts of asparagus officinalis l. is described. this method supports very good growth and eliminates the need to periodically replenish culture medium lost to evaporation. | 1988 | 24241419 |
| promotion of flower formation by atrazine and diuron in seedlings of asparagus. | flower formation in 25-d-old seedling of asparagus officinalis l was increased by soaking the seeds for 12 d in solutions of atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) or diuron (3-(3,4-dichlorophenyl)-1,1-dimethylurea), two herbicides known to affect electron flow of photosystem ii, from approx. 4% in controls to 37% in treatments with 400 μm of atrazine or about 100 μm diuron. both herbicides inhibited plant growth, but treatment of seeds with other growth inhibitors (abs ... | 1986 | 24232563 |
| compartmentation and fluxes of inorganic phosphate in photosynthetic cells. | an analysis of the compartmentation and fluxes of inorganic phosphate in isolated cladophyll cells from asparagus officinalis was made in parallel with an ultrastructural study. the elution pattern of labelled inorganic phosphate (which indicates that the asparagus cells are behaving as a system of three compartments in series) was used to quantify the fluxes between the vacuole, cytoplasm and free space. a relaxation time of 198 min was calculated for inorganic phosphate exchange between the va ... | 1984 | 24253921 |
| observations on the phosphate status and intracellular ph of intact cells, protoplasts and chloroplasts from photosynthetic tissue using phosphorus-31 nuclear magnetic resonance. | individual pools of intracellular inorganic phosphate (pi) can be observed in the dark in intact cells, protoplasts and chloroplasts from photosynthetic tissue by using 31p nuclear magnetic resonance (n.m.r.). estimates for the ph of vacuolar and extravacuolar compartments are reported although it is shown that intracellular ph is determined by the ph of the suspending medium. mannose treatment of asparagus (asparagus officinalis) cells and spinach (spinacia oleracea) protoplasts results in the ... | 1982 | 7092824 |

| amino acid uptake into cultivated mesophyll cells from asparagus officinalis l. | the uptake of threonine, aspartic acid, and isoleucine into cultivated asparagus cells was examined under culture conditions.transport was linear with time and with the number of cells present in the assay. the upake of the three amino acids obeyed michaelis-menten kinetics with apparent affinities in the range of 0.1 to 0.02 millimolar. azide and 2,4-dinitrophenol caused inhibition of threonine uptake. reciprocal competitive inhibitions were found between threonine, aspartic acid, and isoleucin ... | 1979 | 16660779 |

| generation and screening of t-dna insertion mutants mediated by agrobacterium tumefaciens in the garden asparagus stem blight pathogen phomopsis asparagi. | the garden asparagus stem blight caused by filamentous fungus phomopsis asparagi exposes a serious threat on asparagus production globally. however, to present, we understand poorly about the molecular mechanisms of fungal pathogenicity. to facilitate functional genomics research of p. asparagi, here we developed a highly efficient and stable agrobacterium tumefaciens-mediated transformation approach which yielded 150-200 transformants per 1 × 10(6) conidia. our results indicated that 25 °c, ace ... | 2017 | 28730458 |
| comparative de novo transcriptome profiles in asparagus officinalis and a. kiusianus during the early stage of phomopsis asparagi infection. | asparagus kiusianus, an important wild relative of cultivated asparagus (a. officinalis), exhibits resistance to stem blight disease caused by phomopsis asparagi. however, the mechanisms underlying this resistance are not understood and no transcriptomic or genetic resources are available for this species. de novo transcriptome sequencing of a. officinalis and a. kiusianus stems was performed 24 h after inoculation with p. asparagi. in total, 35,259 and 36,321 transcripts were annotated in a. of ... | 2017 | 28572584 |
| influence of different cultivation systems on bioactivity of asparagus. | evaluation of functional and bioactive compounds of asparagus officinalis l. growing in conventional and organic greenhouse and conventional open - field farming was the aim of this research. polyphenols in cladodes grown conventionally were higher than organic. flavonoids and carotenoids were the highest in cladodes in open field. organic spears were richer in total phenolics (+6.9% and +19.1%) and flavonoids (+4.7% and 16.8%) and showed higher in vitro averages of antioxidant activities by thr ... | 2018 | 29120792 |
| the asparagus genome sheds light on the origin and evolution of a young y chromosome. | sex chromosomes evolved from autosomes many times across the eukaryote phylogeny. several models have been proposed to explain this transition, some involving male and female sterility mutations linked in a region of suppressed recombination between x and y (or z/w, u/v) chromosomes. comparative and experimental analysis of a reference genome assembly for a double haploid yy male garden asparagus (asparagus officinalis l.) individual implicates separate but linked genes as responsible for sex de ... | 2017 | 29093472 |
| comparative transcriptome analysis reveals differentially expressed genes associated with sex expression in garden asparagus (asparagus officinalis). | garden asparagus (asparagus officinalis) is a highly valuable vegetable crop of commercial and nutritional interest. it is also commonly used to investigate the mechanisms of sex determination and differentiation in plants. however, the sex expression mechanisms in asparagus remain poorly understood. | 2017 | 28830346 |
| molecular phylogeny of the genus asparagus (asparagaceae) explains interspecific crossability between the garden asparagus (a. officinalis) and other asparagus species. | the genus asparagus comprises approximately 200 species, some of which are commercially cultivated, such as the garden asparagus (a. officinalis). many asparagus species, including a. officinalis, are dioecious and have been grouped into a subgenus distinct from that of hermaphroditic species. although many interspecific crossings have been attempted to introduce useful traits into a. officinalis, only some of the dioecious species were found to be cross-compatible with a. officinalis. here, mol ... | 2012 | 21947345 |
