DNA from soil mirrors plant taxonomic and growth form diversity.
Ecosystems across the globe are threatened by climate change and human activities. New rapid survey approaches for monitoring biodiversity would greatly advance assessment and understanding of these threats. Taking advantage of next-generation DNA sequencing, we tested an approach we call metabarcoding: high-throughput and simultaneous taxa identification based on a very short (usually <100 bas...
متن کاملOn the growth and form of shoots.
Growing plant stems and shoots exhibit a variety of shapes that embody growth in response to various stimuli. Building on experimental observations, we provide a quantitative biophysical theory for these shapes by accounting for the inherent observed passive and active effects: (i) the active controllable growth response of the shoot in response to its orientation relative to gravity, (ii) prop...
متن کاملOn Growth and Form of Narrative Structures
Narrative is firstly a formal organization, but it is a form that interprets the events giving them meaning. Starting from a reinterpretation of the classical Morphology of the Folktale by Vladimir Propp, we can now note how narrative form and cultural meanings interact with each other. Thus, we remove the “formal” dimension from its traditional segregation to a universe of insubstantial non-th...
متن کاملPlant Development: Differential Growth Rates in Distinct Zones Shape an Ancient Plant Form
A long-standing question in biology is how a group of primordial cells can give rise to complex organs. A new study finds that, in an ancient land plant, growth rate variation patterned by meristematic cells primarily determines shape.
متن کاملEffect of plant growth regulators, fruit thinning, boron and calcium on growth indexs and seed yield of watermelon nuts
Watermelon nuts is widely cultivated in Khorasan Razavi for its edible seed production. Two experiments were therefore, conducted to increase seed production in Bahonar University of Kerman Research Station in 2013 and 2014. In first year, the effects of gibberellic acid (0 and 50 mg/l) and fruit number (1, 2 and 3 fruits /plant) were studied in 4 populations. In second year, the effects of 24-...
