Orientation of biological cells using plane-polarized Gaussian beam optical tweezers [PDF]

Journal of Modern Optics 50(10), 1581-1590 (2003), 2003
Optical tweezers are widely used for the manipulation of cells and their internal structures. However, the degree of manipulation possible is limited by poor control over the orientation of trapped cells. We show that it is possible to controllably align or rotate disc shaped cells - chloroplasts of Spinacia oleracea - in a plane polarised Gaussian ...

Neophytadiene, a Plant Specialized Metabolite, Mediates the Virus‐Vector‐Plant Tripartite Interactions

Advanced Science, EarlyView.
Tomato chlorosis virus (ToCV) infection induces production of neophytadiene, a volatile resulting from chlorophyll degradation that is highly attractive to whiteflies. OBP2, an odorant‐binding protein from insect vector B. tabaci, exhibits a strong binding affinity for neophytadiene.

Management‐induced shifts in rhizosphere bacterial communities contribute to the control of pathogen causing citrus greening disease

Journal of Sustainable Agriculture and Environment, Volume 1, Issue 4, Page 275-286, December 2022., 2022
Abstract Introduction Citrus greening (aka Huanglongbing, HLB) caused primarily by the bacterial pathogen Candidatus Liberibacter asiaticus (CLas) has devastating effects on the global citrus industry. Agricultural management‐induced changes in microbial communities are hypothesised to contribute toward HLB resistance by reducing pathogen titre and ...

Leaf Senescence: The Chloroplast Connection Comes of Age

Plants, 2019
Leaf senescence is a developmental process critical for plant fitness, which involves genetically controlled cell death and ordered disassembly of macromolecules for reallocating nutrients to juvenile and reproductive organs.

Upper Rhine Valley: A migration crossroads of middle European oaks [PDF]

Forest Ecology and Management 304 (2013): pp. 89-98, 2013
The indigenous oak species (Quercus spp.) of the Upper Rhine Valley have migrated to their current distribution range in the area after the transition to the Holocene interglacial. Since post-glacial recolonization, they have been subjected to ecological changes and human impact. By using chloroplast microsatellite markers (cpSSRs), we provide detailed

Manipulating the Light Systemic Signal HY5 Greatly Improve Fruit Quality in Tomato

Advanced Science, EarlyView.
This study establishes that HY5, activated by low‐dose light, acts as a systemic signal to enhance tomato fruit quality by directly promoting carotenoid synthesis and sugar metabolism. These findings demonstrate HY5's mobility from leaves to fruits and its application potential through nighttime LED lighting, offering a practical strategy for crop ...

How a simple chloroplast psbA gene mutation changed world agriculture [PDF]

arXiv, 2023
Atrazine as a weed control tactic profoundly changed world agriculture. Long-term use revealed resistant biotypes, R, with a single base pair mutation of the chloroplast psbA gene. The R phenotype emerged from a sequential cascade of pleiotropic effects from the plastid to the whole plant.

Autophagosome development and chloroplast segmentation occur synchronously for piecemeal degradation of chloroplasts

eLife
Plants distribute many nutrients to chloroplasts during leaf development and maturation. When leaves senesce or experience sugar starvation, the autophagy machinery degrades chloroplast proteins to facilitate efficient nutrient reuse.

Genome hybridization: A universal way for the origin and diversification of organelles as well as the origin and speciation of eukaryotes [PDF]

arXiv, 2023
The origin of organelles (mitochondrion, chloroplast and nucleus) remains enigmatic. The endosymbiotic hypothesis that chloroplasts, mitochondria and nuclei descend from the endosymbiotic cyanobacterium, bacterium and archaebacterium respectively is dominant yet uncompelling, while our discovery of de novo organelle biogenesis in the cyanobacterium ...
