Protein-Carbohydrate Interactions as Part of Plant Defense and Animal Immunity

Molecules, 2015
The immune system consists of a complex network of cells and molecules that interact with each other to initiate the host defense system. Many of these interactions involve specific carbohydrate structures and proteins that specifically recognize and ...

Structure of HrcQ(B)-C, a conserved component of the bacterial type III secretion systems [PDF]

, 2003
Type III secretion systems enable plant and animal bacterial pathogens to deliver virulence proteins into the cytosol of eukaryotic host cells, causing a broad spectrum of diseases including bacteremia, septicemia, typhoid fever, and bubonic plague in ...

Plant/animal interactions during the upper carboniferous

The Botanical Review, 1983
This paper discusses evidence for plant/animal relationships in the Upper Carboniferous. Close interactions are examined from the study of fossil plants and animals preserved in coal swamp and coastal plain environments. Evidence for plant/animal interactions is in the form of: (1) animal morphology, including both vertebrates and invertebrates.

The Strength and Drivers of Bird-Mediated Selection on Fruit Crop Size: A Meta-Analysis

Frontiers in Ecology and Evolution, 2018
In seed-dispersal mutualisms, the number of fruit a plant displays is a key trait, as it acts as a signal for seed dispersers that entails fruit removal and exportation of reproductive units (fruit crop size hypothesis).

Shrubs indirectly increase desert seedbanks through facilitation of the plant community [PDF]

, 2019
The mechanisms supporting positive ecological interactions are important. Foundation species can structure desert biodiversity by facilitating seedbanks of annual plants, but the direct and indirect mechanisms of shrub effects on seedbank have not been ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Spitting Seeds From the Cud: A Review of an Endozoochory Exclusive to Ruminants

Frontiers in Ecology and Evolution, 2019
Given their strong masticatory system and the powerful microbial digestion inside their complex guts, mammalian ruminants have been frequently considered seed predators rather than seed dispersers.

A functional study of AUXILIN-LIKE1 and 2, two putative clathrin uncoating factors in Arabidopsis [PDF]

, 2018
Clathrin-mediated endocytosis (CME) is a cellular trafficking process in which cargoes and lipids are internalized from the plasma membrane into vesicles coated with clathrin and adaptor proteins. CME is essential for many developmental and physiological

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Plant-Animal Interactions: Exciting but Neglected Topic [PDF]

Evolution, 1989
measurement of physiological rates for animals in the wild). Various possibilities exist for overcoming these difficulties, and some, including the use of models, are considered in this book. The discussion of modeling as a means of providing "structured propositions" to be addressed by experiment is of interest but is not comprehensive.
