Interactions with local animal species influence the invasion success of plants
This problem is considered from several perspectives that are described over three chapters. Chapter one concerns seed packaging and addresses three topics: What are the differences in fruit packaging traits such as within-fruit seed distribution, fruit shape, and fruit wall strength? Are there differences in the type and quantity of damage inflicted by the granivore on the fruits? Is…

Misleading results due to multiple mapping locations for the same sequence might occur
In A. squamosa, for example, the beginning of fowering of adult plants, originated from seeds, under specific cultivation conditions, would take at least three years until the characterization of the fruits, limiting the number of genotypes that can be studied, which makes the breeding process slow and expensive. The PCR assay using a combination of the primers…

Studies have shown similarity in morphology between leaves and fruits
Additionally, many free‐ending veins were observed in bip0663 and ‘Lukullus’ leaves , which can promote sugar export . Leaf veins, similar to leaf shapes, also have a remarkable diversity in architecture within and across species. Numerous studies on mutant phenotypes have shown auxin signaling networks play an important role in patterning leaf vasculature . Polar…

Tomato is by far the most widely grown vegetable crop worldwide
Seventeen of these modules had significant Gene Ontology enrichment with each module consisting of transcript abundance pat- terns either predominately regulated by cis- or trans- eQTL . To determine which IL’s are important for module regulation, the median transcript abundance value of module genes for each IL was calculated and used to identify IL’s with significantly altered…

Time had less impact than phenology on beta diversity across all communities
Exploitation of different food resources during periods of resource scarcity, as well differences in foraging heights, may allow these closely related primates to live in sympatry. Tutin and Fenandez compared the diets of sympatric chimpanzees and gorillas at Lope, Gabon and found a high degree of dietary overlap, particularly for fruits. Importantly, they found that…

The function of anthocyanin in the biology of the pomegranate tree is not yet fully understood
Total lipid content in the seeds was 18.1–21.5% and 0.2–0.3% in the non-seed fraction. Punicic acid was the predominant fatty acid in the seed lipids and linoleic acid was the major fatty acid in the non-seed fraction. All the varieties had the same saturated/unsaturated fatty acids ratio of 0.1 for the seeds and 0.5 for…

Fruits and vegetables host distinct bacterial assemblages on various plant organs
Organized by Allison Carruth and Rachel Lee,“The Cultural Politics of Seeds” symposium will look at how gender, ethnicity, and race shape contemporary cultural and political movements related to seeds. Conceived as a forum for integrating research, policy, activism, and art practice, this event will include day-long event with 3 panels and two keynote talks and…

Ethylene has roles in climacteric fruit ripening and in plant stress response
Tomato suffers from PCI: storage at 0–12 °C followed by returning the fruit to room temperature can lead to a range of symptoms, varying from mild e.g. lack of favor and poor texture, to severe i.e. development of surface lesions, discoloration, accelerated softening, failure of fruit to ripen and higher susceptibility to post harvest decay. Numerous…

SA and JA signaling pathways are generally considered antagonistic
In Arabidopsis leaves infected with the bacterial pathogen Pseudomonas syringae, the ET response factors EIN3 and EIL1 appear to negatively regulate plant immune responses by disrupting the pathogen-induced accumulation of SA . Thus, the decrease in LeEIL4 and LeEIL43 expression during fruit infection may represent a plant strategy to modulate the intensity of the ET…

Proanthocyanidins are colorless phenolic polymers that show brown coloration upon oxidation
As for our third question regarding the effect of species removal on plant reproductive success, the loss of the migratory hummingbird is associated with negative effects in California and positive effects in Mexico . In the case of California, Ribes sanguineum shows decreased fruit set after the loss of the migratory hummingbird , and all…
