Abstract:
The Anthurium andraeanum `Kaumana' flower growth and development before and after emergence was studied. The process before emergence was long and slow. A tiny flower bud, about 0.3 cm long was formed 80 days before its emergence. The whole period before emergence was divided into three phases: cell division phase, slow growth phase and elongation phase. The characteristic of each phase was studied.The leaf which bears the flower bud at its petiole base is called subtending leaf. Its growth had a significant influence on the flower bud growth at its petiole base. Detaching the young subtending

Abstract:
In the experiment conducted in the greenhouse, the different doses of UV-B radiation applied to the two species Avena fatua and Setaria viridis induced changes in leaf and plant morphology. It was a decrease of plant height, fresh mass of leaves, shoots and roots as well as leaf area. Besides, it caused the leaf curling in both of the species. The significant differences between Avena fatua and Setaria viridis in the studied traits were mainly due to the tillering ability of the species. The content of chlorophyll varied considerably.

Abstract:
Leaf shape in cotton is regulated by the developmental age of the shoot and by several major genes that affect leaf lobing. The effect of these factors was investigated by allometric analysis, cell lineage analysis, and by studying the expression of the leaf shape mutation, Okra, in genetic mosaics. Allometric analysis of leaf growth suggests that leaf shape is determined during the initiation of the primordium rather than during the expansion phase of leaf growth. Clonal analysis demonstrates that both the rate and duration of cell division are fairly uniform throughout the leaf. Cells in the

Data on leaf plastochron, flower growth and bud abortion in greenhouse-grown A. andreanum were collected from a commercial nursery throughout the year, and additional data were obtained from growers. The leaf plastochron duration was fairly constant from Mar. until Sep. at an average of 72 days. Around 10 Oct. the duration was more than doubled. It then decreased linearly to 72 days again, resulting in high leaf production around Apr. Leaf plastochron seemed to be related to radiation but daylength was probably not involved, as leaf emergence continued during winter. The longest period between

NI plants had greater leaf and stem dry weights and leaf area at 72 days; however, only stem dry weights differed at 86 days. The leaf : stem and leaf area : leaf dry weight ratios were always greater for SI than for NI plants, but NI plants produced twice

ABSTRACT: Formation of organ shape is an intriguing yet largely unanswered question in developmental biology. Shapes arise as a result of tightly controlled spatial variation in the rates and directions of tissue expansion over the course of development; therefore, quantifying these growth patterns could provide information about the underlying mechanisms of morphogenesis. Here we present a novel technique and computational tools for quantifying growth and shape changes in developing leaves, with a few unique capabilities.

The composition of the Earth’s atmosphere is changing. Such changes can largely be attributed either directly or indirectly to anthropogenic activities. However, the effects that these changes will have on terrestrial vegetation in the future, represents an area of great uncertainty. The results that have been published in the literature have generally concluded that elevated atmospheric carbon dioxide concentration ([eCO2]) causes increased above- and below-ground biomass compared to ambient conditions.

Optimum nutritional levels for most commercial hardwoods of eastern Canada are unknown. This thesis dealt with the development of a method to determine nutritional standards using within site variation in tree growth and foliar chemistry. To this end, sugar maple (n = 87) and red maple (n = 39) trees were sampled in summer 2001 at the Station de biologie des Laurentides. Leaves were sampled for nutrients (N, P, K, Ca, Mg and Mn) and tree stems were measured for determination of basal area growth (BAG). Similar measurements for trees sampled annually during 1995--2001 were also used to m

Abstract:
The size and shape of plant leaves are extremely diverse within and among species, and are also sensitive to growth conditions. Compound leaves, such as those of tomato, maintain morphogenetic activity during early stages of their development, enabling them to elaborate lateral appendages such as leaflets. The aim of the research project was to understand the interaction between the plant hormone auxin, the putative auxin response inhibitor ENTIRE (E, SlIAA9) and the NAM/CUC transcription factor GOBLET (GOB) in compound-leaf development in tomato (Solanum lycopersicum).

Abstract:
Postharvest leaf senescence contributes to quality losses in flowers and leafy vegetables. The general goal of this research project was to investigate the regulatory mechanisms involved in dark-induced leaf senescence. The regulatory system involved in senescence induction and control is highly complex and possibly involves a network of senescence promoting pathways responsible for activation of the senescence-associated genes. Pathways involving different internal signals and environmental factors may have distinctive importance in different leaf senescence systems. Darkness is known to have

Abstract:
Background and objectives: Manipulation of plant organ growth is one of the primary reasons for the success of mankind allowing increasing amounts of food for human and livestock consumption. In contrast with the successful selection for desirable growth characteristics using plant breeding, transgenic manipulations with single genes has met limited success. While breeding is based on accumulation of many small alterations of growth, usually arise from slight changes in expression patterns, transgenic manipulations are primarily based on drastic, non-specific up-regulation or knock down of gen

Abstract:
Background to the topic: Early tomato fruit development is executed via extensive cell divisions followed by cell expansion concomitantly with endoreduplication. The signals involved in activating the different modes of growth during fruit development are still inadequately understood. Addressing this developmental process, we identified SlFSM1 as a gene expressed specifically during the cell-division dependent stages of fruit development. SlFSM1 is the founder of a class of small plant specific proteins containing a divergent SANT/MYB domain (Barg et al 2005). Before initiating this project,

Abstract:
Tomato yellow leaf curl geminivirus (TYLCV) is a major pathogen of cultivated tomato, causing up to 100% crop loss in many parts of the world. In Israel, where TYLCV epidemics have been recorded since the 1960' s, this viral disease is well known and has been of economic significance ever since. In recent years, TYLCV outbreaks also occurred in the "New World" - Cuba, The Dominican Republic, and in the USA, in Florida, Georgia and Louisiana. Thus, TYLCV substantially hinders tomato growth throughout the world. Surprisingly, however, little is known about the molecular mechanisms of TYLCV inter

Abstract:
In broilers, the immediate post-hatch handling period exposes chicks to cold or hot thermal stress, with potentially harmful consequences to product quantity and quality that could threaten poultry meat marketability as a healthy, low-fat food. This lower performance includes adverse effects on muscle growth and damage to muscle structure (e.g., less protein and more fat deposition). A leading candidate for mediating the effects of thermal stress on muscle growth and development is a unique group of skeletal muscle cells known as adult myoblasts (satellite cells). Satellite cells are multipote

Abstract:
Natural resources are an important source for development, and Latin America is one of the regions with the highest endowment. This calls for a reconsideration of resource-based development. Ambitious countries are moving toward high-value activities and more diversified economies to continue moving up the development ladder. In this sense, the resurgence of industrial policy can correct market failures and lead to the implementation of mission-oriented policies.
