Priming Bean Seedlings to Boost Natural Plant Defenses Against Common Bacterial Wilt: Leaf Architecture, Leaf area, Foliage Water Content, and Plant Biomass Results (Part 3)

Water stress of sugarbeet as related to leaf and canopy temperatures and to leaf Water content

Bacterial anoxygenic photosynthesis on plant leaf surfaces.

The aerial surface of plants, the phyllosphere, is colonized by numerous bacteria displaying diverse metabolic properties that enable their survival in this specific habitat. Recently, we reported on the presence of microbial rhodopsin harbouring bacteria on the top of leaf surfaces. Here, we report on the presence of additional bacterial populations capable of harvesting light as a means of su...

Airborne induction and priming of plant defenses against a bacterial pathogen.

Herbivore-induced plant volatiles affect the systemic response of plants to local damage and hence represent potential plant hormones. These signals can also lead to "plant-plant communication," a defense induction in yet undamaged plants growing close to damaged neighbors. We observed this phenomenon in the context of disease resistance. Lima bean (Phaseolus lunatus) plants in a natural popula...

Plant Leaf Recognition

Research on automatic leaf classification has been active since 2000. Lots of hand-crafted features have been proposed, ranging from shape based, to statistical texture and margin related [2] [3] [1]. Also generic computer vision object recognition features, such SIFT[32] and HOG[33], are studied for this problem. Most of such manually engineered features achieve excellent accuracy on clean ima...
