Abstract:
... MADS-box is the important transcription factor involved in the process of nutritional and reproductive growth of plants. To explore the information of MADS-box transcription factors in carrots (Daucus carota L.), we conducted a genome-wide identification and characteristic analysis of MADS-box in carrot. A total of 104 MADS-box factors were identified, and 48 Type Ⅰ MADS-box factors were classifie ...
... Xanthoceras sorbifolium Bunge is an important woody oilseed tree in north China. However, its yield is severely restricted by a low ratio of female to male flowers, and little is known about the physiological and molecular mechanisms underlying the sex differentiation of flowers. Therefore, carrying out the research in its sex differentiation regulation mechanism is the basis of increasing seed yi ...
... Accessible chromatin regions (ACRs) are tightly associated with gene expressions in the genome. Conserved non-coding cis-regulatory elements, such as transcription factor binding motifs, are usually found in ACRs, indicating an essential regulatory role of ACRs in the plant genome architecture. However, there have been few studies on soybean ACRs, especially those focusing on specific tissues. Hen ...
... Four arbutin derivatives were isolated from the buds of Vaccinium dunalianum in which 4-hydroxyphenyl-6′-(3''-O-β-D-glucopyranosyl-4''-hydroxycinnamoyl)-O-β-D-glucopyranoside (1) was a new compound. The structure of the new compound was determined on the basis of NMR and HR-ESI-MS data. All the arbutin derivatives were subjected to the MS/MS analyses from which the MS/MS spectrometric fragmentatio ...

Abstract:
... Aluminum (Al)-accumulating plants are distributed worldwide. In the Cerrado vegetation in South America, these plants occur as few woody species from Melastomataceae, Rubiaceae, Syplocaceae and Vochysiaceae. Nevertheless, Al assessments are usually limited to their leaves. In this field study, we measured the Al concentration in different vegetative and reproductive structures of Miconia albicans ...

Abstract:
... Herbaceous peony is a kind of perennial herbaceous flowering plant and most varieties are highly dependent on ramet propagation. Some varieties, such as Paeonia × ‘Coral Charm’, have characteristics of relatively easy root cutting propagation. However, underlying adventitious buds of root cutting, the molecular mechanisms are still not completely understood. Here, we collected four key stages of a ...

Abstract:
... Forecasting bud physiologic conditions can help ‘Fuji’ apple farmers manage their orchards more efficiently. Being able to determine the nature of a bud before bud burst is one such forecast that could be of use to these ‘Fuji’ growers. The aim of this research project was to determine if a device, a visible/near-infrared spectrometer, could be employed to determine whether a bud is a flower or no ...

Abstract:
... The effect of average daily temperature (ADT) on flower bud development and subsequent time to flower was investigated on hybrid impatiens (Impatiens ×hybrida) cultivars Compact Electric Orange, Compact Hot Coral, and Compact Orchid Blush. Plants with a visible flower bud measuring 2 mm in width were placed in one of the four greenhouses with temperature setpoints ranging from 16 to 28 °C. Flower ...
flower buds, etc ; acclimation; agronomy; cotton; genotype; heat stress; mesophyll; photosynthesis; temperature; Show all 9 Subjects
Abstract:
... Cotton is often exposed to high temperatures during the reproductive stage, which can negatively affect its productivity. The objectives were to: i) test whether heat stress impacts during the reproductive stage on photosynthesis are due to instant temperature effects or to acclimation produced during the heat stress period, ii) evaluate the role of stomatal and mesophyll conductance on net photos ...

Abstract:
... Plants provide extrafloral nectar, which is a food resource taken by ants, especially aggressive species that may act as plant guards. To our knowledge, no study has been conducted to concurrently investigate the fluctuation of plant fitness over its whole reproductive season, recording and comparing both short periods (different samplings during the plant’s reproductive season) and the season/poo ...

Abstract:
... This study examines the means of reducing the damage to the branches of Camellia oleifera in the process of vibration picking and solving the problems of low equipment-development efficiency and slow product renewal caused by using traditional test methods to determine vibration picking parameters. In this study, the optimal vibration parameters were determined by using the self-response (branch a ...
