Herein, we sought to explore the contribution of cellulose biosynthesis to the shape and morphogenesis of hexagonal seed coat cells in Arabidopsis (Arabidopsis thaliana). Consistent with seed preferential expression of CELLULOSE SYNTHASE9 (CESA9), null mutations in CESA9 caused no change in cellulose content in leaves or stems, but caused a 25% reduction in seeds. Compositional studies of cesa9...

One hitherto intractable problem in studying mast seeding (synchronous intermittent heavy flowering by a population of perennial plants) is determining the relative roles of weather, plant reserves, and evolutionary selective pressures such as predator satiation. We parameterize a mechanistic resource-based model for mast seeding in Chionochloa pallens (Poaceae) using a long-term individually s...

Depletable storage systems use media such as NAND flash that has a limited lifetime, which decreases with more usage. Such systems treat write cycles, in addition to space, as a constrained resource of the system. Depletable storage systems must be equipped to monitor writes, attribute depletion to appropriate applications, and even control the rate of depletion. We outline the new functionalit...

In order to identify the effects of different levels of nitrogen fertilizer on seed yield and seed growth indices of some bread and durum wheat genotypes, a field experiment was conducted in 2013-2014 in Khuzestan Agricultural and Natural Resource Research Center. The experiment was designed as a split plot with three replications. Nitrogen application rates (50, 100 and 150 kg N.ha-1) were ass...

Across six field and lab experiments, we found that impaired self-control fosters compliance with charitable requests. Experiments 1 and 2 showed that self-regulatory resource depletion was induced when participants yielded to the initial requests of a foot-in-the-door script aimed at procuring volunteer behavior. Experiment 3 demonstrated that self-regulatory resource depletion mediated the ef...

This paper presents a resource-light acquisition of morphological paradigms and lexicon for fusional languages. It builds upon Paramor [10], an unsupervised system, by extending it: (1) to accept a small seed of manually provided word inflections with marked morpheme boundary; (2) to handle basic allomorphic changes acquiring the rules from the seed and/or from previously acquired paradigms. Th...

Context-dependency in species interactions is widespread and can produce concomitant patterns of context-dependent selection. Masting (synchronous production of large seed crops at irregular intervals by a plant population) has been shown to reduce seed predation through satiation (reduction in rates of seed predation with increasing seed cone output) and thus represents an important source of ...

It has been consistently demonstrated that people tend to perform more poorly on subsequent self-control tasks after completing an initial task that requires them to exert self-control (Hagger et al., 2010; Hagger and Chatzisarantis, 2014). The predominant explanation of such depletion effect claims that self-control taxes a limited resource that becomes drained with use (Muraven and Baumeister...

The widespread production and utilization of plastic products have become ingrained in our society, resulting a staggering amount waste, severe environmental challenges, resource depletion.
