Plants have evolved intricate strategies to withstand attacks by herbivores and pathogens. Although it is known that plants change their primary and secondary metabolism in leaves to resist and tolerate aboveground attack, there is little awareness of the role of roots in these processes. This is surprising given that plant roots are responsible for the synthesis of plant toxins, play an active...

The principles of plant physiology are best learned in an environment where students are directly engaged in the process of scientific inquiry. Working from this assumption, we have developed a two-stage approach to laboratory instruction that fosters student-directed research within an undergraduate plant physiology course. During the first 10 weeks of a 16week semester, students develop compe...

knowledge of the relation between agronomical traits with economical yield is very important in crop improvement and breeding. in order to study of genetic diversity and identifying yield components, 568 kabuli type germplasm and 390 desi type chickpea germplasm that were available in pulses collection of faculty of agriculture, university of tehran, was investigated in this research in 2009 in...

objective: yield components and genetic contribution have the most important in final yield and breeding programs of crop plants. for this purpose, 20 varieties of grapevines with russia origin were evaluated in urmia and takestan research station (under full irrigation and drought stress). methods: twenty grapevine genotypes were evaluated in urmia and takestan research station (under full irr...

in order to study the effects of planting date and plant density on yield and its components in three chickpea (cicer arietinum l.) cultivars in rainfed conditions of ilam, a field experiment was carried out using split plot design as factorial by complete randomized block design with three replications at shirvan-chardavol agriculture research station during 2008-2009. sowing dates were assign...

Like the skeleton of any vertebrate animal, the cytoskeleton plays a major role in detennining the three-dimensional form of a cell. However, in plants the cytoskeleton is probably more analogous to a scaffold, being directly involved in the establishment of cell morphology and less involved in the maintenance of cell shape once the relatively rigid cell walls are in place. The term "skeleton" ...

This paper completes the proof of the Lp-boundedness of bilinear operators associated to nonsmooth symbols or multipliers begun in Part I, our companion paper [8], by establishing the corresponding Lp-boundedness of time-frequency paraproducts associated with tiles in phase plane. The affine invariant structure of such operators in conjunction with the geometric properties of the associated pha...
