Fitness consequences of altering floral circadian oscillations forNicotiana attenuata [PDF]
Journal of Integrative Plant Biology, 2017 AbstractEcological interactions between flowers and pollinators are all about timing. Flower opening/closing and scent emissions are largely synchronized with pollinator activity, and a circadian clock regulates these rhythms. However, whether the circadian clock increases a plant's reproductive success by regulating these floral rhythms remains ...

An Endophytic Trichoderma Strain Promotes Growth of Its Hosts and Defends Against Pathogen Attack
Frontiers in Plant Science, 2020 Plants host numerous endophytic microbes which promote plant performance, in particular under stress. A new endophytic fungus was isolated from the leaves of a deciduous wood tree Leucas aspera.

Native bacterial endophytes promote host growth in a species-specific manner; phytohormone manipulations do not result in common growth responses. [PDF]
PLoS ONE, 2008 BackgroundAll plants in nature harbor a diverse community of endophytic bacteria which can positively affect host plant growth. Changes in plant growth frequently reflect alterations in phytohormone homoeostasis by plant-growth-promoting (PGP ...

Antimicrobial peptide expression in a wild tobacco plant reveals the limits of host-microbe-manipulations in the field [PDF]
, 2019 Plant-microbe associations are thought to be beneficial for plant growth and resistance against biotic or abiotic stresses, but for natural ecosystems, the ecological analysis of microbiome function remains in its infancy.

Consistency of Nicotiana attenuata's Herbivore- and Jasmonate-Induced Transcriptional Responses in the Allotetraploid Species Nicotiana quadrivalvis and Nicotiana clevelandii [PDF]
Plant Physiology, 2004 Abstract We examined the consistency of the native diploid Nicotiana attenuata (Na)'s herbivore-induced transcriptional changes in the two allotetraploid natives, Nicotiana clevelandii (Nc) and Nicotiana quadrivalvis (Nq), which are thought to be derived from hybridizations with an ancestral Na. An analysis of nuclear-encoded chloroplast-

Evolution of a novel and adaptive floral scent in wild tobacco
, 2020 Many plants emit diverse floral scents that mediate plant-environment interactions and attain reproductive success. However, how plants evolve novel adaptive floral volatiles remains unclear. Here, we show that in the wild tobacco, Nicotiana attenuata, a

Priming of anti-herbivore defence in Nicotiana attenuata by insect oviposition: herbivore-specific effects [PDF]
, 2016 Oviposition by Spodoptera exigua on Nicotiana attenuata primes plant defence against its larvae that consequently suffer reduced performance. To reveal whether this is a general response of tobacco to insect oviposition or species-specific, we ...
