Drought stress adaptation: metabolic adjustment and regulation of gene expression Tập 132 Số 1 - Trang 21-32 - 2013
S. Bhargava, Kshitija Sawant
AbstractPlants cope with drought stress by manipulating key physiological
processes like photosynthesis, respiration, water relations, antioxidant and
hormonal metabolism. There exist multiple and often redundant stress sensors,
which transduce the stress signal through secondary signalling molecules to the
nucleus, where the expression of stress‐response genes is regulated.

A new DNA extraction method for high‐throughput marker analysis in a large‐genome species such as Triticum aestivum Tập 120 Số 4 - Trang 354-356 - 2001
Nils Stein, Gerard Herren, Beat Keller
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... hiện toàn bộ
Breeding for increased nitrogen‐use efficiency: a review for wheat (T. aestivum L.) Tập 135 Số 3 - Trang 255-278 - 2016
Fabien Cormier, J. Foulkes, Bertrand Hirel, David Gouache, Yvan Moënne‐Loccoz, Jacques Le Gouis
AbstractNitrogen fertilizer is the most used nutrient source in modern
agriculture and represents significant environmental and production costs. In
the meantime, the demand for grain increases and production per area has to
increase as new cultivated areas are scarce. In this context, breeding for an
efficient use of nitrogen became a major objective. In wheat, nitrogen is
required to maintain a ... hiện toàn bộ
Genetic diversity in camelina germplasm as revealed by seed quality characteristics and RAPD polymorphism Tập 124 Số 5 - Trang 446-453 - 2005
J. Vollmann, H. Grausgruber, Gertraud Stift, V. Dryzhyruk, T. Lelley
AbstractCamelina is an alternative oilseed crop species with limited information
about the origin and diversity of available germplasm. Therefore, a set of 130
camelina accessions from a world collection was evaluated for oil content,
protein content and 1000‐seed weight in field experiments grown in three
macro‐environments in Austria. Based on phenotypic data, accessions were
categorized into fo... hiện toàn bộ
The Experimental and Commercial Release of Transgenic Crop Plants Tập 111 Số 1 - Trang 1-22 - 1993
Phillip J. Dale, Judith A. Irwin, Jodi Scheffler
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... hiện toàn bộ
Association of leaf rust and powdery mildew resistance in a recombinant derived from a Hordeum vulgare × Hordeum bulbosum hybrid Tập 117 Số 1 - Trang 83-84 - 1998
R. A. Pickering, B. J. Steeffenson, A. M. Hill, I. G. Borovkova
AbstractWhile studying powdery mildew resistance in a recombinant line (code
81882) derived from a Hordeum vulgare (cv. ‘Vada’) ×Hordeum bulbosum hybrid, a
low infection type of resistance to leaf rust was observed. To determine the
mode of inheritance of the leaf rust resistance and whether there was linkage
between the two resistances, F2 and F3 progenies from crosses between 81882 and
‘Vada’ we... hiện toàn bộ
Molecular genetic diversity within and among German ecotypes in comparison to European perennial ryegrass cultivars Tập 124 Số 3 - Trang 257-262 - 2005
Snježana Bolarić, Susanne Barth, Albrecht E. Melchinger, K. Ulrich Posselt
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... hiện toàn bộ
Veery wheats carry an allele of Vrn‐A1 that has implications for freezing tolerance in winter wheats Tập 130 Số 4 - Trang 413-418 - 2011
H. A. Eagles, Karen Cane, Ben Trevaskis
With 1 figure and 5 tables AbstractTwo winter alleles of Vrn‐A1 were recently
found in wheat cultivars adapted to the Great Plains of the USA. Using a
diagnostic marker for a single‐nucleotide polymorphism (SNP) in exon 4, which
distinguishes the alleles, the allele in the Great Plains cultivar ‘Jagger’ was
common in Australian and CIMMYT cultivars, but ‘Veery’ cultivars carried the
alternate alle... hiện toàn bộ
