ani increased leucocytosis (probablv from its close relationship to nucleic acicl), and on this account may increase the incidence of empyrema. To Professor Titherlv is due the identificationi, as allantoin, of the active priinciple of comfrey root, also its complete investigation. If the continued and extendedl use of comfrev coinfirms the authior's results, he will have performed a notable se...
The evolutionary history of gains and losses of vegetative reproductive propagules (soredia) in Porpidia s.l., a group of lichen-forming ascomycetes, was clarified using Bayesian Markov chain Monte Carlo (MCMC) approaches to monophyly tests and a combined MCMC and maximum likelihood approach to ancestral character state reconstructions. The MCMC framework provided confidence estimates for the r...
Annual plants grow vegetatively at early developmental stages and then transition to the reproductive stage, followed by senescence in the same year. In contrast, after successive years of vegetative growth at early ages, woody perennial shoot meristems begin repeated transitions between vegetative and reproductive growth at sexual maturity. However, it is unknown how these repeated transitions...
1. A fundamental trade-off among vascular plants between traits inferring rapid resource acquisition and those leading to conservation of resources has now been accepted broadly, but is based on empirical data with a strong bias toward leaf traits. Here we test whether interspecific variation in traits of different plant organs obeys this same trade-off and whether within-plant trade-offs are c...
Traits Associated For Adaptation To Water Limited Environment Of Cereal Crops A Review Of Literature
Cereal crops mainly cultivated as a rainfed crops, where grain yield is often limited by terminal drought stress. Therefore, ability of plants to withstand drought is an important aspect of crop production in water limited conditions. In this context grain yield is closely related to post-anthesis water availability. Hence, grain yield can be increased by restricting pre anthesis water use to m...
Previously, the GRF-INTERACTING FACTOR1 (GIF1)/ANGUSTIFOLIA3 (AN3) transcription coactivator gene, a member of a small gene family comprising three genes, was characterized as a positive regulator of cell proliferation in lateral organs, such as leaves and flowers, of Arabidopsis (Arabidopsis thaliana). As yet, it remains unclear how GIF1/AN3 affects the cell proliferation process. In this stud...
Small Shorea stenoptera Burck. (Dipterocarpaceae) trees of reproductive age growing in an arboretum in west Java were studied to determine the pattern of vegetative shoot development, the time and method of floral initiation and the effect of paclobutrazol on floral enhancement. Vegetative buds were enclosed by two stipules between which was a leaf primordium, a small axillary vegetative bud an...
Positron emission tomography (PET) techniques represent a useful tool to better understand the residual brain function in vegetative state patients. It has been shown that overall cerebral metabolic rates for glucose are massively reduced in this condition. However, the recovery of consciousness from vegetative state is not always associated with substantial changes in global metabolism. This f...
quality are influenced by many factors, including climatic conditions and production practices. In subtropical climates, the temperature usually falls below 70°F for several months during winter. This period of cool temperatures causes growth to cease and citrus trees to become dormant for about three months. The cool temperatures during this dormant period promote floral induction. When warm s...
