Plant genome size variation: bloating and purging DNA.
Plant genome size variation is a dynamic process of bloating and purging DNA. While it was thought plants were on a path to obesity through continual DNA bloating, recent research supports that most plants activity purge DNA. Plant genome size research has greatly benefited from the cataloguing of genome size estimates at the Kew Plant DNA C-values Database, and the recent availability of over ...
متن کاملBiophysical and size-dependent perspectives on plant evolution.
Physical laws and processes have profoundly influenced plant evolution. Their effects are invariably size dependent and thus subject to scaling as well as biophysical analyses even though these effects differ depending upon the fluid (water or air) in which plants evolve. Although organisms cannot obviate the effects of physical laws and processes, the consequences of these effects can be alter...
متن کاملSize Variation in Streptococcal
Streptococcal M protein, the fibrillar molecule on the surface of the group A streptococcus, is considered to be one of the major factors responsible for the ability of this human pathogen to cause disease (1). Though type-specific opsonic antibodies directed towards the M molecule enable the infected host to clear the invading streptococcus (1, 2), the ability of this organism to vary its anti...
متن کاملCell-size dependent progression of the cell cycle creates homeostasis and flexibility of plant cell size
Mean cell size at division is generally constant for specific conditions and cell types, but the mechanisms coupling cell growth and cell cycle control with cell size regulation are poorly understood in intact tissues. Here we show that the continuously dividing fields of cells within the shoot apical meristem of Arabidopsis show dynamic regulation of mean cell size dependent on developmental s...
متن کاملChanges in size and form in the dominant phytoplankton species in the southern Caspian Sea
Due to the recent destructive pressures on the Caspian environment, an effect on phytoplankton communities is expected in different aspects such as cell size and form. This paper aims to survey the size and form in the dominant phytoplankton species in the years of 1996, 2001, 2006, 2009, 2011 and 2012 in the Iranian coast of the Caspian Sea. Results of current study showed that the dominant sp...
