large-scale project to convert the rice plant to the C4 mechanism. Around a dozen genes are required for the process, a few of which have already been transferred to the rice plant. The bigger challenge, however, lies in the fact that the anatomy of the leaves has to be adapted to keep the initial carbon fixation reaction separated from the RuBisCO reaction. This might still take a while. Simil...

A prerequisite for reliable hydraulic measurements is an accurate collection of the plant material. Thereby, the native hydraulic state of the sample has to be preserved during harvesting (i.e., cutting the plant or plant parts) and preparation (i.e., excising the target section). This is particularly difficult when harvesting has to be done under transpiring conditions. In this article, we pre...

Although this study aims to develop an improved method for the preservation of reserve lipids in plant tissues for different uses in plant anatomy, it mostly aims to develop an improved method for the identification of lipid reserves where synthesis or storage occurs. The proposed procedures entail only the utilization of (2-hydroxyethyl)-methacrylate (HEMA) as a dehydration agent. One of the p...

Sida acuta Burm.f. (Fam. Malvaceae) is used in Siddha system of medicine and in folk medical practice in Tamil Nadu under the names Arivalmooku pachilai or vattatiruppi. The leaves of this plant are used for their diuretic, demulcent, anthelmintic and wound healing properties. The present paper discusses the anatomy of petiole leaf and stem, microscopic constants, physico-chemical standards and...

The general Markov plus invariable sites (GM+I) model of biological sequence evolution is a two-class model in which an unknown proportion of sites are not allowed to change, while the remainder undergo substitutions according to a Markov process on a tree. For statistical use it is important to know if the model is identifiable; can both the tree topology and the numerical parameters be determ...

Despite the introduction of likelihood-based methods for estimating phylogenetic trees from phenotypic data, parsimony remains the most widely-used optimality criterion for building trees from discrete morphological data. However, it has been known for decades that there are regions of solution space in which parsimony is a poor estimator of tree topology. Numerous software implementations of l...
