William Morris (1834-1896) was a famous artist and designer in Europe the 19th century, founder of Arts Crafts movement father modern design, with pivotal position design world. The patterns he designed take animals plants nature as elements integrate them into his own pattern design. Through regular arrangement, created vivid elegant patterns, which influenced designers from generation to gene...

Plants perceive microbial invaders using pattern recognition receptors that recognize microbe-associated molecular patterns. In this study, we identified RESPONSIVENESS TO BOTRYTIS POLYGALACTURONASES1 (RBPG1), an Arabidopsis (Arabidopsis thaliana) leucine-rich repeat receptor-like protein, AtRLP42, that recognizes fungal endopolygalacturonases (PGs) and acts as a novel microbe-associated molecu...

In general, plants and arbuscular mycorrhizal (AM) fungi exchange photosynthetically fixed carbon for soil nutrients, but occasionally nonphotosynthetic plants obtain carbon from AM fungi. The interactions of these mycoheterotrophic plants with AM fungi are suggested to be more specialized than those of green plants, although direct comparisons are lacking. We investigated the mycorrhizal inter...

In nature, plants constantly have to face pathogen attacks. However, plant disease rarely occurs due to efficient immune systems possessed by the host plants. Pathogens are perceived by two different recognition systems that initiate the so-called pattern-triggered immunity (PTI) and effector-triggered immunity (ETI), both of which are accompanied by a set of induced defenses that usually repel...

β-glucans are cell wall constituents of bacteria, yeast, fungi, and plants. They are not expressed in mammalian cells, but they are recognized by mammalian cells as pathogen-associated molecular patterns by pattern recognition receptors and thus act as biological response modifiers. This review summarizes data on the hematopoiesis-stimulating effects of β-glucans, as well as on their ability to...

ALTERATIONS IN BIOCHEMICAL COMPONENTS IN MESTA PLANTS: Yellow vein mosaic disease of mesta (kenaf, Hibiscus cannabinus L.; and roselle, H. sabdariffa L.) is a new entrant to the disease scenario and it is associated with a novel monopartite Begomovirus. Changes in different biochemical parameters in diseased mesta plants were observed as compared to healthy ones. Isozyme pattern and assays of d...

Winter survial during an annual cycle of temperateand boreal-zone woody perennials is a multicomponent response. Two of these components are: (1) the timing, rate, and extent of cold acclimation (CA; Box 1), and (2) plants’ ability to sufficiently maintain its freezing tolerance (FT) until the danger of killing frosts is passed which is determined by, among other factors, plants’ ability to res...

The goal of this tutorial is to provide an overview of recent systematic constructions to deal with plants having redundant actuators. For these plants, the presence of multiple actuators with overlapping features presents an interesting allocation problem, typically encompassing a suitable performance goal that pertains the selected input pattern. Within the tutorial we plan to cover a number ...

We demonstrate how phyllotaxis (the arrangement of leaves on plants) and the ribbed, hexagonal, or parallelogram planforms on plants can be understood as the energy-minimizing buckling pattern of a compressed sheet (the plant's tunica) on an elastic foundation. The key idea is that the elastic energy is minimized by configurations consisting of special triads of periodic deformations. We study ...

Like animals, plants use asymmetric cell divisions to create pattern and diversity. Due to a rigid cell wall and lack of cell migrations, these asymmetric divisions incur the additional constraints of being locked into their initial orientations. How do plants specify and carry out asymmetric divisions? Intercellular communication has been suspected for some time and recent developments identif...
