Book excerpt: Spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. Spores thus differ from gametes, which are reproductive cells that must fuse in pairs in order to give rise to a new individual. Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction. Spores are produced by bacteria, fungi, algae, and plants.Bacterial spores serve largely as a resting, or dormant, stage in the bacterial life cycle, helping to preserve the bacterium through periods of unfavourable conditions. Spore production is particularly common among Bacillus and Clostridium bacteria, several species of which are disease-causing. Many bacterial spores are highly durable and can germinate even after years of dormancy.Bacillus megaterium, an endospore-forming bacterium. The nearly mature spore is visible within the mother cell (magnified about 17,000 times).Among the fungi, spores serve a function analogous to that of seeds in plants. Produced and released by specialized fruiting bodies, such as the edible portion of the familiar mushrooms, fungal spores germinate and grow into new individuals under suitable conditions of moisture, temperature, and food availability.Many larger algae reproduce by spores and are also capable of sexual reproduction. A number of red algae species produce monospores (walled nonflagellate spherical cells) that are carried by water currents and form a new organism upon germination. Some green algae produce nonmotile spores, called aplanospores, whereas others produce motile zoospores, which lack true cell walls and bear one or more flagella. The flagella allow zoospores to swim to a favourable environment in which to develop, whereas monospores and aplanospores must rely on passive transport by water currents.Among plants-all of which have a life cycle characterized by alternating generations of asexually and sexually reproducing individuals-spores are the reproductive agents of the asexual generation. Produced by the sporophyte (i.e., spore-bearing) generation, plant spores give rise to the haploid gametophyte (i.e., gamete-bearing) generation. Spores are most conspicuous in the non-seed-bearing plants, including liverworts, hornworts, mosses, and ferns. In these lower plants, as in fungi, the spores function much like seeds. In general, the parent plant sheds the spores locally; the spore-generating organs are frequently located on the undersides of leaves. The spores of plants that inhabit the edges of bogs or lakes are frequently shed into the water or are carried there by rain and are preserved in the sediments. Wind dispersal is a factor in plants that shed their spores explosively.Among the seed-bearing plants-the gymnosperms and the angiosperms-the haploid spores are far less conspicuous. They are not released from the parent plant, but rather they germinate into microscopic gametophyte individuals that are entirely dependent upon the diploid sporophyte plant. Gymnosperms and angiosperms form two kinds of spores: microspores, which give rise to male gametophytes, and megaspores, which produce female gametophytes.

Available in PDF, EPUB and Kindle. Book excerpt: The Study of Plants in a Whole New Light “Matt Candeias succeeds in evoking the wonder of plants with wit and wisdom.” ―James T. Costa, PhD, executive director, Highlands Biological Station and author of Darwin's Backyard #1 New Release in Nature & Ecology, Plants, Botany, Horticulture, Trees, Biological Sciences, and Nature Writing & Essays In his debut book, internationally-recognized blogger and podcaster Matt Candeias celebrates the nature of plants and the extraordinary world of plant organisms. A botanist’s defense. Since his early days of plant restoration, this amateur plant scientist has been enchanted with flora and the greater environmental ecology of the planet. Now, he looks at the study of plants through the lens of his ever-growing houseplant collection. Using gardening, houseplants, and examples of plants around you, In Defense of Plants changes your relationship with the world from the comfort of your windowsill. The ruthless, horny, and wonderful nature of plants. Understand how plants evolve and live on Earth with a never-before-seen look into their daily drama. Inside, Candeias explores the incredible ways plants live, fight, have sex, and conquer new territory. Whether a blossoming botanist or a professional plant scientist, In Defense of Plants is for anyone who sees plants as more than just static backdrops to more charismatic life forms. In this easily accessible introduction to the incredible world of plants, you’ll find: • Fantastic botanical histories and plant symbolism • Passionate stories of flora diversity and scientific names of plant organisms • Personal tales of plantsman discovery through the study of plants If you enjoyed books like The Botany of Desire, What a Plant Knows, or The Soul of an Octopus, then you’ll love In Defense of Plants.

Available in PDF, EPUB and Kindle. Book excerpt: Part A and Part B of the fifth of twelve volumes of The Mycota deal with the mechanisms of interactions between fungi and plants and consider pathogenic as well as mutualistic associations. Nobody involved in the manipulation of plant populations can afford to ignore the fungi, so pervasive and important are fungus/plant interactions for the well-being of plant communities, both managed and natural. Consequently, these volumes will be of interest to a broad range of professionals involved in agriculture, forestry, horticulture, and conservation as well as plant pathology, mycology, ecology, and evolution.
Download or read book Diagnosing Hemp and Cannabis Crop Diseases written by Shouhua Wang and published by CABI. This book was released on 2021-08-18 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hemp and cannabis, both belonging to Cannabis sativa, have emerged as some of the most valuable crops because of their multiple functionalities - industrial, medicinal, and recreational uses. Like all other crops, they are at risk of diseases and pests. In certain cases, an entire hemp field can fail due to unexpected disease. As a new and highly regulated crop, research on Cannabis crop diseases is scarce, and the science of plant diagnostics is not well covered in the literature. Taking hemp/cannabis as a model crop, the book illustrates how to diagnose a disease problem and how to manage it effectively. It presents real disease cases encountered during crop production, and explains methods of diagnosis, both in the field and in the lab, in order to find out the cause(s).
