Desiccation tolerance
-
Trehalose-6-phosphate synthase (TPS) serves important functions in plant desiccation tolerance and response to environmental stimuli. At present, a comprehensive analysis, i.e. functional classification, molecular evolution, and expression patterns of this gene family are still lacking in Solanum tuberosum (potato).

The annual killifish Austrofundulus limnaeus inhabits ephemeral ponds in northern Venezuela, South America, and is an emerging extremophile model for vertebrate diapause, stress tolerance, and evolution. Embryos of A. limnaeus regularly experience extended periods of desiccation and anoxia as a part of their natural history and have unique metabolic and developmental adaptations. Currently, there are limited genomic resources available for gene expression and evolutionary studies that can take advantage of A. limnaeus as a unique model system.

Tardigrades are renowned for their ability to enter cryptobiosis (latent life) and endure extreme stress, including desiccation and freezing. Increased focus is on revealing molecular mechanisms underlying this tolerance.

During maturation seeds acquire several physiological traits to enable them to survive drying and disseminate the species. Few studies have addressed the regulatory networks controlling acquisition of these traits at the tissue level particularly in endospermic seeds such as tomato, which matures in a fully hydrated environment and does not undergo maturation drying.

Desiccation tolerant Selaginella species evolved to survive extreme environmental conditions. Studies to determine the mechanisms involved in the acquisition of desiccation tolerance (DT) have focused on only a few Selaginella species.

Filmy-ferns (Hymenophyllaceae) are poikilohydric, homoiochlorophyllous desiccation-tolerant (DT) epiphytes. They can colonize lower and upper canopy environments of humid forest.

Water shortage is a major factor that harms agriculture and ecosystems worldwide. Plants display various levels of tolerance to water deficit, but only resurrection plants can survive full desiccation of their vegetative tissues.

Pyropia haitanensis, distributes in the intertidal zone, can tolerate water losses exceeding 90%. However, the mechanisms enabling P. haitanensis to survive harsh conditions remain uncharacterized.

An attempt was made to isolate and characterize the desiccation tolerant rhizobacteria from arid regions of Karnataka. A total of nine desiccation tolerant rhizobacteria were isolated from soil samples collected from arid regions of Chitradurga, Gadag and Koppal districts. These isolates were further subjected to morphological and biochemical studies. The Gram staining study of the nine isolates revealed thatCHI-1, CHI-2, CHI-3, and CHI-5 are Gram negative. The other isolates viz., CHI-4, GAD-1, GAD-2, KOP-1 and KOP-2 are Gram positive.

This first exploratory study on the seed physiology of Acer trautvetteri, a broadleaved tree found in Caucasia and northern Turkey, demonstrated that A. trautvetteri seeds exhibit physiological dormancy and require about 3 months of chilling for complete dormancy loss.

Why consider the role of place in Milton’s poetry? A few years ago, while attending a seminar conducted by Diane McColley on the relation of nature to culture in the literary history of the natural world, I found myself returning again and again to the same question: what happens when culture is privileged over place? No mere academic question, as the last acres of the place my family had farmed for generations had given way to bulldozers the year before, I found myself feeling that I had somehow lost my place in the world....

Diversity of plant form and life history and their distribution onto different habitats suggest that plant functions should underlie this diversity, providing tools to successfully and differentially thrive in every habitat. The knowledge of these functions is then the key to understand community and ecosystem structure and functioning, something that attracted the interest and effort of many plant ecologists trying to establish patterns of adaptive specialization in plants.

Over the past decade, our understanding of plant adaptation to environmental stress, including both constitutive and inducible determinants, has grown con- siderably. This book focuses on stress caused by the inanimate components of the environment associated with climatic, edaphic and physiographic factors that substantially limit plant growth and survival. Categorically these are abiotic stresses, which include drought, salinity, non-optimal temperatures and poor soil nutrition.
