Blue-light-receptor cryptochrome (CRY), which mediates cotyledon expansion, increased accumulation of anthocyanin, and inhibition of hypocotyl elongation, was first identified in Arabidopsis. Two Arabidopsis cryptochromes (AtCRY1 and AtCRY2) have been reported to be localized to the nucleus. However, there is no information on the cryptochromes in monocotyledons. In this study, we isolated two ...

Many angiosperms, both monocotyledons and dicotyledons, heavily impregnate their vegetative and reproductive organs with solid particles of silicon dioxide (SiO(2)) known as opaline phytoliths. The underlying mechanisms accounting for the formation of phytoliths in plants are poorly understood, however. Using wild and domesticated species in the genus Cucurbita along with their F(1) and F(2) pr...

BACKGROUND It is imperative to have reliable and timely methodologies for analysis and monitoring of seed plants in order to determine climate-related plant processes. Moreover, impact of environment on plant fitness is predominantly based on studies of female functions, while the contribution of male gametophytes is mostly ignored due to missing data on pollen quality. We explored the use of i...

A large number of studies Cistus ladanifer highlight this Mediterranean shrub as a source the phenolic compounds responsible for allelopathic potential species. There are few present in C. that have not yet been studied. The objective work was to evaluate activity estragole and 2-isopropylphenol on filter paper soil monocotyledons (Allium cepa) dicotyledons (Lactuca sativa). results showed when...

Benzoxazinoids (BXs) are phytochemicals that exert plant-protecting, allelopathic, and human-health-promoting effects. Here, we present a data-dependent acquisition-mass spectrometry based method to locate annotate BX-conjugates in different fractions of plant extract. This allows for isolation compounds much smaller percentage than common natural products yet still sufficient subsequent identi...

Background: Pakistan has a unique biodiversity of monocotyledon flora and due to its climatic condition huge number medicinal plants are distributed in the area. Ethnobotany plays crucial role understanding dynamic relationships between biological diversity social cultural systems. However, studies about ethnomedicinal significance monocot taxa very limited. Methods: This study documented indig...

The objective was to evaluate weed phytosociology and similarities between crop management systems in the Chapadões region. experiment conducted at agricultural area located municipality of Chapadão do Sul, MS, during 2016/17 harvest. Three managements strategies were used: (1) cotton/soybean/Urochloa, (2) millet/soybean/millet (3) millet/soybean/crotalaria. A phytosociological survey weeds car...

Aim We expand on community phylogenetic approaches to Darwin's Naturalization Conundrum by considering scale, comprised of grain and extent. assess relatedness between invasive, non-native native plant species at multiple depths in the phylogeny (i.e. grain) across clades extents) regional local spatial scales highly fragmented, critically imperilled pine rockland ecosystem. Location Miami-Dade...

The mitogen-activated protein kinase (MAPK) phosphatases (MKPs) are negative regulators of MAPKs. In dicotyledons such as Arabidopsis and tobacco, MKPs have been shown to play pivotal roles in abiotic stress responses, hormone responses and microtubule organization. However, little is known about the role of MKPs in monocotyledons such as rice. Database searches identified five putative MKPs in...

Early studies on seagrass photosynthesis (e.g. Drew 1978) usually began by explaining that seagrasses are relatively primitive monocotyledons, closely related to freshwater plants but able to live in the marine environment. Presently, many introductions start by highlighting the importance of seagrasses in overall marine productivity and their subsequent economical importance (e.g. Duarte & Ceb...
