Lettuce (Lactuca sativa 'Salinas') seeds fail to germinate when imbibed at temperatures above 25 degrees C to 30 degrees C (termed thermoinhibition). However, seeds of an accession of Lactuca serriola (UC96US23) do not exhibit thermoinhibition up to 37 degrees C in the light. Comparative genetics, physiology, and gene expression were analyzed in these genotypes to determine the mechanisms gover...

The aim of this paper was to map the scientific research on soybean physiology by usingbibliographic review and analyses of papers indexed up to July 31, 2014 in the web of sciencedatabase. A total of 1682 non-redundant bibliographic records were curated. The soybeanphysiology research experienced two major periods. The first period was from 1943 when thefirst soybean paper was published to 198...

Winter chilling is of central importance in the phenology of temperate annual and perennial plants. Chilling accelerates flowering through the process of vernalization and breaks both bud and seed dormancy, permitting the onset of growth in the spring. The quantitative effects of chilling in floral promotion in winter annual Arabidopsis accessions are well-documented, but very little is known a...

Dietary elements, commonly known as dietary minerals are chemical elements required by living organisms other than the elements present in the common organic molecules. Dietary fibre and minerals are important for healthy functioning of the human body. The mineral nutrition is an important aspect and its pivotal role in human life provides healthy growth. The present study was undertaken to ana...

Reactive Oxygen Species (ROS) play a key role in various events of seed life. In orthodox seeds, ROS are produced from embryogenesis to germination, i.e., in metabolically active cells, but also in quiescent dry tissues during after ripening and storage, owing various mechanisms depending on the seed moisture content. Although ROS have been up to now widely considered as detrimental to seeds, r...

Seed mass in species-rich moist tropical forests often varies over six or more orders of magnitude (Foster, 1982; Foster and Janson, 1985; Hammond and Brown, 1995). Most of these species, including some with the minutest seeds (Metcalfe, 1996; Metcalfe and Grubb, 1997), can be classified as ‘shade-tolerant’ with the ability to establish beneath a closed canopy. Seeds of the shade-tolerators var...

background: psoriasis is a common chronic and relapsing skin disease with unknown etiology being observed at any age and any gender, having a 1. 5-3% prevalence rate among the general population. psoriatic lesions consist of pruritic and scaling papules, residing on an erythematous base, which are more commonly found on the scalp, extensor surfaces, palms and soles, and the nails. the conventio...

The effect of exposing Amaranthus hypochondriacus plants to different levels photosynthetic photon flux densities (PPFD) duringdevelopment was analyzed in this work. Mature exposed full sunlight (38.8 mol m-2 d-1) had higher instantaneous rates net CO2 uptake (An), reducing sugars content and thicker leaves, but lower chlorophyll leaf number per plant than those developed under reduced PPFD (19...
