Microsatellite Development and Application in Pigeonpea (Cajanus cajan (L.) Millsp.)
(2006)
Pigeonpea is a major legume crop grown in the semi-arid tropics but has been relatively neglected in terms of genomic research. This study aimed at developing molecular markers as a basic requirement towards initiating ...
Forest fragmentation and plant-pollinator interactions in Western Kenya
(2006)
Rain forest fragmentation can affect plant-pollinator interactions and the reproductive success of plant species. Understanding these consequences is a crucial component of conserving vulnerable ecosystems.
In this ...

Molecular evolution, phylogenetics and biogeography in southern hemispheric bryophytes with special focus on Chilean taxa
(2005)
Researchers have long been fascinated by disjunct distribution patterns of plant and animal species. Especially the disjunctly distributed species occurring in the temperate Chilean and New Zealand rainforests of the ...
Molecular and physiological characterization of transgenic Arabidopsis plants expressing different aldehyde dehydrogenase (ALDH) genes
(2005)
Various reactive molecules such as aldehydes and their intermediates accumulate in plants exposed to environmental stress conditions. These molecules are highly toxic and can cause peroxidation of cellular lipids, protein ...
Untersuchungen zu den Auswirkungen atmosphärischer Stickstoffeinträge auf epiphytische Flechten und Moose im Hinblick auf die Bioindikation
(2004)
In unterschiedlich stark belasteten Regionen Nordrhein-Westfalens wurde die Epiphytenflora erfasst. Das Vorkommen und die Häufigkeit einiger Arten sind eng mit der Stickstoffbelastung der Standorte korreliert. Landesweit ...
Untersuchungen zur Wirkung ausgewählter Akzeleratoren auf die Mobilität nichtionischer Wirkstoffe unterschiedlicher Polarität in isolierten Kutikularmembranen
(2004)
Die pflanzliche Kutikularmembran (CM) ist eine mit dem Wachs imprägnierte asymmetrische heterogene Barrieremembran (Polymermembran). An der morphologischen Außenseite der pflanzlichen CM ist eine sehr dünne, partiell ...
Molecular analysis of the plastid-targeted gene and protein (CpPTP-1) associated with desiccation tolerance in the resurrection plant Craterostigma plantagineum
(2021-01-28)
Water scarcity causes drought stress and enormous losses in agricultural production, and consequently this leads to a worldwide food crisis. Craterostigma plantagineumis one of the best studied resurrection plants that is ......
Characterization of drought stress regulator CBF/DREB genes in Hordeum vulgare: Expression analysis in ten different barley cultivars
(2013-07-08)
Improving crop yield under water deficit environments is an urgent task for crop breeding worldwide. Many efforts have been made to identify key regulators of plant drought stress responses. Most of these studies have been ......
Vegetation and climate history of the southern Levant during the last 30,000 years based on palynological investigation
(2013-07-09)
Paleo-vegetation of northern Israel is reconstructed from palynological data over the Late Pleistocene and Holocene, and related to climate variation in the Levant, as well as anthropogenic impact on vegetation. Being ...
Die pflanzlichen Biopolyester Kutin und Suberin: Chemische Zusammensetzung und Biosynthese
(2013-05-15)
Ziel meiner Arbeit war es, anhand ausgewählter Lipidstoffwechsel-Mutanten Rückschlüsse auf die Beteiligung der untersuchten Gene an der Polyesterbildung von Kutin und Suberin zu ziehen. Untersucht wurden die Polyesterzus ......
