Flowering dynamics and pollinator visitation of oilseed echium (Echium plantagineum).

Numai utilizatorii înregistrați pot traduce articole

Echium (Echium plantagineum L.) is an alternative oilseed crop in summer-wet temperate regions that provides floral resources to pollinators. Its seed oil is rich in omega-3 fatty acids, such as stearidonic acid, which is desired highly by the cosmetic industry. Seeds were sown in field plots over

Endophytic Beauveria bassiana promotes drought tolerance and early flowering in corn.

Numai utilizatorii înregistrați pot traduce articole

Beauveria bassiana (Bals.) Vuillemin (B. bassiana) is an entomopathogenic fungus that establishes endophytic symbiosis with plants. In the present study, the effects of B. bassiana strains colonization in growing Zea mays L. (Z. mays), crop production, and drought tolerance were evaluated. Z. mays

ZmCCA1a on Chromosome 10 of Maize Delays Flowering of Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

Maize (Zea mays) is a major cereal crop that originated at low latitudes, and thus photoperiod sensitivity is an important barrier to the use of tropical/subtropical germplasm in temperate regions. However, studies of the mechanisms underlying circadian regulation in maize are at an early

Validation of Dwarf8 polymorphisms associated with flowering time in elite European inbred lines of maize (Zea mays L.).

Numai utilizatorii înregistrați pot traduce articole

The timing of transition from vegetative growth to flowering is important in nature as well as in agriculture. One of several pathways influencing this transition in plants is the gibberellin (GA) pathway. In maize (Zea mays L.), the Dwarf8 (D8) gene has been identified as an orthologue of the

Epigenetic signatures of stress adaptation and flowering regulation in response to extended drought and recovery in Zea mays.

Numai utilizatorii înregistrați pot traduce articole

During their lifespan, plants respond to a multitude of stressful factors. Dynamic changes in chromatin and concomitant transcriptional variations control stress response and adaptation, with epigenetic memory mechanisms integrating environmental conditions and appropriate developmental programs

Enhancement of development of larval Anopheles arabiensis by proximity to flowering maize (Zea mays) in turbid water and when crowded.

Numai utilizatorii înregistrați pot traduce articole

To determine whether proximity to flowering maize enhances the development of larval anopheline mosquitoes breeding in turbid water and when crowded, we evaluated the development of larval Anopheles arabiensis under various conditions of turbidity, larval density, and proximity to pollen-shedding

Dual functions of ZmNF-YA3 in photoperiod-dependent flowering and abiotic stress responses in maize.

Numai utilizatorii înregistrați pot traduce articole

Nuclear factor-Y (NF-Y) transcription factors are important regulators of several essential biological processes, including embryogenesis, drought resistance, meristem maintenance, and photoperiod-dependent flowering in Arabidopsis. However, the regulatory mechanisms of NF-Ys in maize (Zea mays) are

Apoplastic infusion of sucrose into stem internodes during female flowering does not increase grain yield in maize plants grown under nitrogen-limiting conditions.

Numai utilizatorii înregistrați pot traduce articole

Nitrogen (N) limitation reduces leaf growth and photosynthetic rates of maize (Zea mays), and constrains photosynthate translocation to developing ears. Additionally, the period from about 1 week before to 2 weeks after silking is critical for establishing the reproductive sink capacity necessary to

[Reaction of the seedlings of flowering plants to the effects of imino-di-(paradimethylaminophenyl)-methane-aurine-00].

Numai utilizatorii înregistrați pot traduce articole

The influence of auramine-00 on seedlings of three species of plants - Cucurbita pepo L., Helianthus annuus L., Zea mays L.-was investigated. Auramine was added in agar-agar, on which the seedlings were growing. Two concentrations of auramine were used--0.001%. Besides the delay in growth, also the

Proteome profile of maize (Zea Mays L.) leaf tissue at the flowering stage after long-term adjustment to rice black-streaked dwarf virus infection.

Numai utilizatorii înregistrați pot traduce articole

Maize rough dwarf disease (MRDD) is a viral disease and causes great yield loss. To better understand the effects of MRDD on plant growth and metabolism, comparative proteomic analysis of leaves from virus-infected and normal plants was performed. In order to eliminate the interference of

ZmCOL3, a CCT gene represses flowering in maize by interfering with the circadian clock and activating expression of ZmCCT.

Numai utilizatorii înregistrați pot traduce articole

Flowering time is a trait vital to the adaptation of flowering plants to different environments. Here, we report that CCT domain genes play an important role in flowering in maize (Zea mays L.). Among the 53 CCT family genes we identified in maize, 28 were located in flowering time quantitative

Is Change in Ovary Carbon Status a Cause or a Consequence of Maize Ovary Abortion in Water Deficit during Flowering?

Numai utilizatorii înregistrați pot traduce articole

Flower or grain abortion causes large yield losses under water deficit. In maize (Zea mays), it is often attributed to a carbon limitation via the disruption of sucrose cleavage by cell wall invertases in developing ovaries. We have tested this hypothesis versus another linked to the expansive

Functional mechanisms of drought tolerance in subtropical maize (Zea mays L.) identified using genome-wide association mapping.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Earlier studies were focused on the genetics of temperate and tropical maize under drought. We identified genetic loci and their association with functional mechanisms in 240 accessions of subtropical maize using a high-density marker set under water stress. RESULTS Out of 61 significant

Effects of ethylenediurea (EDU) on regulatory proteins in two maize (Zea mays L.) varieties under high tropospheric ozone phytotoxicity

Numai utilizatorii înregistrați pot traduce articole

Rising tropospheric ozone is a major threat to the crops in the present climate change scenario. To investigate the EDU induced changes in proteins, two varieties of maize, the SHM3031 and the PEHM5, (hereafter S and P respectively) were treated with three EDU applications (0= control, 50 and 200

MaizeNet: a co-functional network for network-assisted systems genetics in Zea mays.

Numai utilizatorii înregistrați pot traduce articole

Maize (Zea mays) has multiple uses in human food, animal fodder, starch and sweetener production and as a biofuel, and is accordingly the most extensively cultivated cereal worldwide. To enhance maize production, genetic factors underlying important agricultural traits, including stress tolerance
