To grow or not to grow: a stressful decision for plants.
Progress in improving abiotic stress tolerance of crop plants using classic breeding and selection approaches has been slow. This has generally been blamed on the lack of reliable traits and phenotyping methods for stress tolerance. In crops, abiotic stress tolerance is most often measured in terms of yield-capacity under adverse weather conditions. "Yield" is a complex trait and is determined ...
متن کاملTo grow or not to grow: nutritional control of development during Caenorhabditis elegans L1 arrest.
It is widely appreciated that larvae of the nematode Caenorhabditis elegans arrest development by forming dauer larvae in response to multiple unfavorable environmental conditions. C. elegans larvae can also reversibly arrest development earlier, during the first larval stage (L1), in response to starvation. "L1 arrest" (also known as "L1 diapause") occurs without morphological modification but...

Aurora B puts chromosomes in their place mall molecule inhibitors of Aurora B activity, characterized by Hauf et al. (page 281) and Ditchfield et al. (page 267), reveal that the mammalian kinase and its budding yeast counterpart, Ipl1, have similar functions. Without Aurora B, mistakes in kinetochore–chromosome interactions go uncorrected. Early evidence of a function for the Aurora family in c...
متن کاملCell growth: How to grow and where to grow
Root hairs provide a model system for studying tip growth in plants. The recent cloning of genes required for tip growth has shed new light on the link between ionic regulation, cell wall assembly and the cytoskeleton in cell growth.
متن کاملWill an Asymptomatic Meningioma Grow or Not Grow? A Meta-analysis.
BACKGROUND The treatment strategy for patients with an asymptomatic meningioma is still controversial. Key to an optimal decision is a careful evaluation of the growth possibilities of the meningioma by taking the patient's clinicoradiologic factors into consideration. However, previous studies have disagreed about the risk factors relating to tumor growth. METHODS A comprehensive search of P...
