Background and Aims Specific leaf area (SLA), a key element of the ‘worldwide leaf economics spectrum’, is the preferred ‘soft’ plant trait for assessing soil fertility. SLA is a function of leaf dry matter content (LDMC) and leaf thickness (LT). The first, LDMC, defines leaf construction costs and can be used instead of SLA. However, LT identifies shade at its lowest extreme and succul…

Komentar Bagikan
Kent J. BradfordHiroyuki Nonogaki

The formation, dispersal, and germination of seeds are crucial stages in the life cycles of gymnosperm and angiosperm plants. The unique properties of seeds, particularly their tolerance to desiccation, their mobility, and their ability to schedule their germination to coincide with times when environmental conditions are favorable to their survival as seedlings, have no doubt contributed s…

Edible insects: future prospects for food and feed security
Komentar Bagikan
Arnold van Huis [et.al.]

Insects are often considered a nuisance to human beings and mere pests for crops and animals. Yet this is far from the truth. Insects provide food at low environmental cost, contribute positively to livelihoods, and play a fundamental role in nature. However, these benefits are largely unknown to the public. Contrary to popular belief, insects are not merely “famine foods” eaten in time…

Komentar Bagikan
Susan E. HartleyMihail GarbuzovStefan Reidinger

Background and Aims The herbivore defence system of true grasses (Poaceae) is predominantly based on silicon that is taken up from the soil and deposited in the leaves in the form of abrasive phytoliths. Silicon uptake mechanisms can be both passive and active, with the latter suggesting that there is an energetic cost to silicon uptake. This study assessed the effects of plant-available soil …

Cristina PignocchiJohn H. Doonan

Background and Aims The cell cycle-regulated protein ENDOSPERM DEFECTIVE 1 (EDE1) is a novel plant microtubule-associated protein essential for plant cell division and for microtubule organization in endosperm. EDE1 is only present on microtubules at mitosis and its expression is highly cell cycle regulated both at the protein and the transcript levels. Methods To search for EDE1-interacting …

Insights into a hydration regulating system in Cupressus pollen grains
Komentar Bagikan
R. Danti [et.al.]

Background and Aims Hydration, rupture and exine opening due to the sudden and large expansion of intine are typical of taxoid-type pollen grains. A hemispheric outgrowth external to the exine was observed on Cupressus and Juniperus pollen grains before the intine swelling and exine release. However, the actual existence of this permanent or temporary structure and its precise role in pollen hy…

Aure´lie C. M. Vialette-Guiraud [et.al.]

Background and Aims The closely related NAC family genes NO APICAL MERISTEM (NAM) and CUPSHAPED COTYLEDON3 (CUC3) regulate the formation of boundaries within and between plant organs. NAM is post-transcriptionally regulated by miR164, whereas CUC3 is not. To gain insight into the evolution of NAM and CUC3 in the angiosperms, we analysed orthologous genes in early-diverging ANA-grade angiospe…

John A. BryantStephen J. Aves

Background The initiation of DNA replication is a very important and highly regulated step in the cell division cycle. It is of interest to compare different groups of eukaryotic organisms (a) to identify the essential molecular events that occur in all eukaryotes, (b) to start to identify higher-level regulatory mechanisms that are specific to particular groups and (c) to gain insights into th…

M. Arro´niz-Crespo [et.al.]

Background and Aims Anthropogenic depletion of stratospheric ozone in Arctic latitudes has resulted in an increase of ultraviolet-B radiation (UV-B) reaching the biosphere. UV-B exposure is known to reduce aboveground biomass and plant height, to increase DNA damage and cause accumulation of UV-absorbing compounds in polar plants. However, many studies on Arctic mosses tended to be inconclusive…

Masahiro M. Kanaoka [et.al.]

Background and Aims During sexual reproduction in higher angiosperms, the pollen tubes are directed to the ovules in the pistil to deliver sperm cells. This pollen tube attraction is highly species specific, and a group of small secreted proteins, TfCRPs, are necessary for this process in Torenia fournieri. Methods A candidate pollen tube attractant protein in Torenia concolor, a related spec…

Romain Barillot [et.al.]

Background and Aims Most studies dealing with light partitioning in intercropping systems have used statistical models based on the turbid medium approach, thus assuming homogeneous canopies. However, these models could not be directly validated although spatial heterogeneities could arise in such canopies. The aim of the present study was to assess the ability of the turbid medium approach to …

Background and Scope In eukaryotes, chromatin remodelling complexes are shown to be responsible for nucleosome mobility, leading to increased accessibility of DNA for DNA binding proteins. Although the existence of such complexes in plants has been surmised mainly at the genetic level from bioinformatics studies and analysis of mutants, the biochemical existence of such complexes has remained …

Maaike De Ridder [et.al.]

Background and Aims Density is a crucial variable in forest and wood science and is evaluated by a multitude of methods. Direct gravimetric methods are mostly destructive and time-consuming. Therefore, faster and semito non-destructive indirect methods have been developed. Methods Profiles of wood density variations with a resolution of approx. 50 mm were derived from one-dimensional resistanc…
