The Impact of Different Long‐Term Storage Conditions on the Viability of Lichen‐Forming Ascomycetes and their Green Algal Photobiont, Trebouxia spp.
Plant Biology - Tập 5 Số 3 - Trang 324-330 - 2003
Abstract: Lichen‐forming ascomycetes and their green algal photobionts
completely die off within approximately 3 years of storage at room temperature.
Macroscopically this is recognizable as a colour change, the green shades of the
chlorophylls being lost. In fluorescent light microscopy preparations an
increase in fungal autofluorescence and a significant decrease in chlorophyll
autofluorescence ...
Emerging concept for the role of photorespiration as an important part of abiotic stress response
Plant Biology - Tập 15 Số 4 - Trang 713-722 - 2013
AbstractWhen plants are exposed to stress, generation of reactive oxygen species
(ROS) is often one of the first responses. In order to survive, cells attempt to
down‐regulate the production of ROS, while at the same time scavenging ROS.
Photorespiration is now appreciated as an important part of stress responses in
green tissues for preventing ROS accumulation. Photorespiratory reactions can
diss...
Natural hybridisation betweenQuercus petraea(Matt.) Liebl. andQuercus pubescensWilld. within an Italian stand as revealed by microsatellite fingerprinting
Plant Biology - Tập 11 Số 5 - Trang 758-765 - 2009
EST Sequencing, Annotation and Macroarray Transcriptome Analysis Identify Preferentially Root‐Expressed Genes in Sugar Beet
Plant Biology - Tập 4 Số 6 - Trang 700-710 - 2002
Abstract: An integrated approach involving EST sequencing, data mining and
multiparallel expression profiling by macroarray analysis was established to
classify sugar beet gene products with respect to their expression in three
different organs. The DNA sequences of 2996 ESTs derived from young sugar beet
plants specified 2048 unique gene products with putative functions in primary
and secondary m...
Adaptability of winter wheat Dongnongdongmai 1 (Triticum aestivum L.) to overwintering in alpine regions
Plant Biology - Tập 23 Số 3 - Trang 445-455 - 2021
Abstract Long winters led to a one‐crop‐a‐year cultivation system until the
winter wheat Dongnongdongmai 1 (Dn1) was successfully cultivated in northeast
China. This crop variety is resistant to extremely low temperatures (−35 °C). To
better understand the adaptability of winter wheat Dn1 to low temperatures, gas
chromatography time‐of‐flight mass spectrometry (GC‐TOF/MS) and metabolomics
analysis...
Pollinator‐independent orchid attracts biotic pollinators due the production of lipoidal substances
Plant Biology - Tập 20 Số 2 - Trang 182-190 - 2018
Abstract Flowering plants often depend on the attraction of biotic pollinators
for sexual reproduction. Consequently, the emergence and maintenance of selected
floral attributes related to pollinator attraction and rewarding are driven by
pollinator pressure. In this paper we explore the effect of pollinators,
rainfall, temperature and air humidity on the reproduction of a Brazilian
terrestrial or...
Reciprocal style polymorphisms are not easily categorised: the case of heterostyly inLithodoraandGlandora(Boraginaceae)
Plant Biology - Tập 13 Số s1 - Trang 7-18 - 2011
AbstractInterest in reciprocal floral polymorphisms, such as heterostyly, has
increased in recent decades because they can be used as suitable model systems
to study mechanisms of outbreeding and disassortative mating in plants.
Heterostylous plants are characterised by the presence of discrete morphs that
differ in sex organ position and in some other ancillary traits. As regards sex
organ deploy...
Gas Exchange and Growth Responses of Ectomycorrhizal Picea mariana, Picea glauca, and Pinus banksiana Seedlings to NaCl and Na2SO4
Plant Biology - Tập 8 Số 5 - Trang 646-652 - 2006
Abstract: Black spruce (Picea mariana), white spruce (Picea glauca), and jack
pine (Pinus banksiana) seedlings were inoculated with Hebeloma crustuliniforme
or Laccaria bicolor and subjected to NaCl and Na2SO4 treatments. The effects of
ectomycorrhizas on salt uptake, growth, gas exchange, and needle necrosis varied
depending on the tree and fungal species. In jack pine seedlings,
ectomycorrhizal ...
Fungal carbohydrate support in the ectomycorrhizal symbiosis: a review
Plant Biology - Tập 12 Số 2 - Trang 292-301 - 2010
AbstractEctomycorrhizal (ECM) symbiosis is a mutualistic interaction between
certain soil fungi and fine roots of perennial plants, mainly forest trees, by
which both partners become capable of efficiently colonising nutrient‐limited
environments. The success of this interaction is reflected in the dominance of
ECM forest ecosystems in the Northern hemisphere. Apart from their economic
importance ...
Effect of Ammonium and Nitrate Nutrition On Some Physiological Processes in Higher Plants ‐ Growth, Photosynthesis, Photorespiration, and Water Relations
Plant Biology - Tập 9 Số 1 - Trang 21-29 - 2007
Abstract: Ammonium and nitrate as different forms of nitrogen nutrients impact
differently on some physiological and biochemical processes in higher plants.
Compared to nitrate, ammonium results in small root and small leaf area, which
may contribute to a low carbon gain, and an inhibition on growth. On the other
hand, due to (photo)energy saving, a higher CO2 assimilation rate per leaf area
was o...
