Fitness consequences of a clock pollinator filter in Nicotiana attenuata flowers in nature [PDF]

Journal of Integrative Plant Biology, 2017
SummaryNicotiana attenuata flowers, diurnally open, emit scents and move vertically to interact with nocturnal hawkmoth and day‐active hummingbird pollinators. To examine the fitness consequences of these floral rhythms, we conducted pollination trials in the plant's native habitat with phase‐shifted flowers of plants silenced in circadian clock genes.

Modulation of Free Amino Acid Metabolism in Carrots Under Postharvest Wounding and Water Stress

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.
Amino acids play a fundamental role in plant metabolism, acting as building blocks for proteins and participating in stress responses as osmolytes and signaling molecules. Carrots (Daucus carota) are widely consumed root vegetables rich in bioactive compounds, including amino acids, which contribute to their nutritional value.

Indirect plant defense may provide economically important pest suppression in sorghum

Pest Management Science, Volume 81, Issue 11, Page 7478-7488, November 2025.
Laboratory measures of sorghum direct and indirect plant resistance traits aligned with natural enemy recruitment and pest suppression in the field. Abstract BACKGROUND A promising strategy to optimize biological control of insect pests is selecting crop varieties with indirect defense traits.

Effects of down-regulating ornithine decarboxylase upon putrescine-associated metabolism and growth in Nicotiana tabacum L.

, 2016
Transgenic plants of Nicotiana tabacum L. homozygous for an RNAi construct designed to silence ornithine decarboxylase (ODC) had significantly lower concentrations of nicotine and nornicotine, but significantly higher concentrations of anatabine ...

The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae) [PDF]

, 2015
Background and Aims: We investigate whether changes in floral colour accompany polyploid and homoploid hybridisation, important processes in angiosperm evolution. Potentially, changes in floral colour can facilitate speciation through pollinator shifts.

CmSGT1, Transcriptionally Regulated by CmWRKY21 and CmWRKY31, Improves Powdery Mildew Resistance in Cucurbita moschata

Plant Direct, Volume 9, Issue 10, October 2025.
ABSTRACT Powdery mildew (PM), mainly caused by Podosphaera xanthii, is a severe destructive disease that threatens the production of cucurbit crops globally. Heterologous transformation has shown that the CmSGT1 gene (suppressor of the G2 allele of skp1) improved PM resistance in tobacco.

Overexpression of miR399d impairs arbuscular mycorrhizal symbiosis in tomato

Plant Biotechnology Journal, Volume 23, Issue 10, Page 4381-4394, October 2025.
Summary Arbuscular mycorrhizal symbiosis (AMS) is a pervasive mutualistic interaction that is prevalent among fungi and the majority of terrestrial plant species. AMS host plants possess an alternative phosphate (Pi) acquisition pathway via arbuscular mycorrhizal fungi (AMF) in addition to direct Pi uptake by the root epidermis.

Tomato prosystemin gene in other Solanaceae [PDF]

, 2009
Systemin, an octadeca-peptide isolated from tomato, is a signalling molecule involved in local and systemic wound response. It regulates the activation of more than twenty defensive genes in tomato plants in response to herbivore attacks.

Development of chloroplast transformation for five species in the genus Nicotiana

The Plant Journal, Volume 124, Issue 2, October 2025.
SUMMARY Technologies for the stable genetic transformation of the plastid (chloroplast) genome are currently restricted to a small number of species. The development of highly efficient tissue culture, regeneration, and selection procedures represents the major hurdle that needs to be overcome to extend the species range of the transplastomic ...

Rapid modification of the insect elicitor N-linolenoyl-glutamate via a lipoxygenase-mediated mechanism on Nicotiana attenuata leaves

BMC Plant Biology, 2010
Background Some plants distinguish mechanical wounding from herbivore attack by recognizing specific constituents of larval oral secretions (OS) which are introduced into plant wounds during feeding.
