Genome‐wide association analysis reveals flowering‐related genes regulating rachis length in rice
Plant Breeding - Tập 135 Số 6 - Trang 677-682 - 2016
AbstractRachis length is correlated with panicle size in rice. Unveiling the
genetic basis of rachis length is important for understanding the genetic
regulation of panicle size. In this study, we performed a genomewide association
study of rachis length using 529 rice accessions from two environments. In
total, 20 loci were identified for rachis length and distributed across the 12
chromosomes ex...
The high and low molecular weight glutenin subunit polymorphism of Algerian durum wheat landraces and old cultivars
Plant Breeding - Tập 124 Số 4 - Trang 338-342 - 2005
Molecular genetic diversity within and among German ecotypes in comparison to European perennial ryegrass cultivars
Plant Breeding - Tập 124 Số 3 - Trang 257-262 - 2005
AbstractPerennial ryegrass (Lolium perenne L.) is the most important grass
species for temperate grassland agriculture. The level and distribution of
genetic variation in gene bank ecotype collections is still largely unknown but
of great interest for the planning of breeding programmes. The objectives of
this study were to (i) assess the molecular variance and population structure of
German ecoty...
Transformation of Medicago sativa L. Using a Ti Plasmid Derived Vector
Plant Breeding - Tập 106 Số 1 - Trang 39-46 - 1991
AbstractA cultivar of Medicago sativa was transformed with Agrobacterium
tumefaciens strain At81 binary‐vector carrying the plasmid pKan3A, with the
neomycin phosphotransferase gene under the control of the mannopine biosynthesis
promoter. Stem segments were infected with the bacterium and kanamycin resistant
calli were obtained; plant regeneration via somatic embryogenesis and
polyembryogenesis w...
The Experimental and Commercial Release of Transgenic Crop Plants
Plant Breeding - Tập 111 Số 1 - Trang 1-22 - 1993
AbstractWith advances in recombinant DNA methods and transformation procedures,
it is possible to transfer genes into crop plants from unrelated plants,
microbes and animals. Many of the modifications being carried out, or envisaged,
are for disease and pest resistance, product quality and tolerance to
environmental stress, but there are additional opportunities to modify crops to
give specialized...
Development of genomic‐derived simple sequence repeat markers in Hevea brasiliensis from 454 genome shotgun sequences
Plant Breeding - Tập 131 Số 4 - Trang 555-562 - 2012
With 2 figures and 2 tablesAbstractIn an attempt to develop additional
microsatellite markers in rubber tree, we employed a 454 pyrosequencing
technology to obtain genomic shotgun sequences and subsequently identified over
24 000 putative simple sequence repeats (SSRs). A total of 418 potential SSR
loci were chosen for an empirical validation. Two hundred and twenty‐four primer
pairs yielded succe...
The resistance to leaf rust and powdery mildew of recombinant lines of barley (Hordeum vulgare L.) derived from H. vulgare × H. bulbosum crosses
Plant Breeding - Tập 126 Số 3 - Trang 259-267 - 2007
AbstractA set of 23 recombinant lines (RLs) of barley (Hordeum vulgare L.)
derived from H. vulgare × H. bulbosum L. crosses was inoculated with barley leaf
rust (Puccinia hordei) and powdery mildew (Blumeria graminis f.sp. hordei) at
the seedling stage to identify their levels and mechanisms of resistance. Eight
RLs were studied further in glasshouse and field tests. All three barley parents
(‘Emi...
A new DNA extraction method for high‐throughput marker analysis in a large‐genome species such as Triticum aestivum
Plant Breeding - Tập 120 Số 4 - Trang 354-356 - 2001
AbstractGene mapping and marker‐assisted selection in complex, polyploid genomes
still relies strongly on restriction fragment length polymorphism (RFLP)
analysis, as conversion of RFLP to polymerase chain reaction (PCR) markers can
be very difficult. DNA extraction in amounts suitable for RFLP analysis
represents the most time‐consuming and labour‐intensive step in molecular marker
analysis of pl...
Hordeum bulbosum‐a new source of disease resistance‐transfer of resistance to leaf rust and mosaic viruses from H. bulbosum into winter barley
Plant Breeding - Tập 119 Số 3 - Trang 215-218 - 2000
AbstractAn outline is given of results for the transfer of new resistances
against leaf rust and barley mosaic viruses from Hordeum bulbosum into winter
barley. Progenies from backcrosses of barley cultivars with H. bulbosum hybrids
were tested both in conventional breeding trials and in additional tests under
controlled conditions. Resistance to both pathogens proved to be stable and of
good heri...
Inheritance and chromosomal location of Septoria passerinii resistance introgressed from Hordeum bulbosum into Hordeum vulgare
Plant Breeding - Tập 122 Số 5 - Trang 405-409 - 2003
AbstractSeptoria speckled leaf blotch (SSLB), caused by Septoria passerinii, has
become one of the most serious diseases of barley in the Upper Midwest region of
the USA. The recombinant line 36L5 derived from a backcross of the susceptible
barley cultivar ‘Emir’ and a resistant Hordeum bulbosum parent Cb2920/4/Colch
was found to be resistant to S. passerinii. Two doubled haploids derived from
36L...
