This first pan-Mediterranean analysis of genetic diversity in wild narrow-leafed lupin revealed strong East-West genetic differentiation of populations, an historic eastward migration, and signatures of genetic adaptation to climatic variables. Most grain crops suffer from a narrow genetic base, which limits their potential for adapting to new challenges such as increased stresses associated with climate change. Plant breeders are returning to the wild ancestors of crops and their close relatives to broaden the genetic base of their crops...

We proudly present the first organic/inorganic hybrid pullulan/SeNPs hybrid microflower material obtained using a simple and bio-inspired strategy. The chemical structures of pullulan, folic acid decorated cationic pullulan (FA-CP) were designed for stabilizing selenium nanoparticles (SeNPs). SeNPs stabilized by FA-CP hybrid microflowers were observed after the addition of a cysteine hydrochloride solution into the solution mixture of Na2SeO3 and FA-CP. We suggested that the concentrations of cysteine and FA-CP were the key factors for the formation of flower-like structure...

Background and Aims: The evolution of selfing from outcrossing may be the most common transition in plant reproductive systems and is associated with a variety of ecological circumstances and life history strategies. The most widely discussed explanation for these associations is the reproductive assurance hypothesis - the proposition that selfing is favoured because it increases female fitness when outcross pollen receipt is limited. Here an alternative explanation, the time limitation hypothesis, is addressed, one scenario of which proposes that selfing may evolve as a correlated response to selection for a faster life cycle in seasonally deteriorating environments...

Metal contaminated soils are increasing worldwide. Metal-tolerant plants growing on metalliferous soils are fascinating genetic and microbial resources. Seeds can vertically transmit endophytic microorganisms that can assist next generations to cope with environmental stresses, through yet poorly understood mechanisms. The aims of this study were to identify the core seed endophyte microbiome of the pioneer metallophyte Crotalaria pumila throughout three generations, and to better understand the plant colonisation of the seed endophyte Methylobacterium sp...

Species flower production and flowering phenology vary from year to year due to extrinsic factors. Inter-annual variability in flowering patterns may have important consequences for attractiveness to pollinators, and ultimately, plant reproductive output. To understand the consequences of flowering pattern variability, a community approach is necessary because pollinator flower choice is highly dependent on flower context. Our objectives were: 1) To quantify yearly variability in flower density and phenology; 2) To evaluate whether changes in flowering patterns result in significant changes in pollen/nectar composition...

Vernalization is one of the pivotal ways for plants to flower. As one of the major cereal crops, wheat is widely planted in the world. In the present study, we applied two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectrometry (MALDI-TOF/TOF MS) to analyze the changes in protein expression profiles in responding to vernalization in leaves of wheat seedling before (0d) and after (30d) of vernalization. The results indicated that among the 68 differentially expressed proteins that were successfully identified under vernalization, 36 were up-regulated whereas 32 were down-regulated at 0 d, respectively...

Vernalization is an important process that regulates the floral transition in plants. MiRNAs are endogenous non-coding sRNA molecules that function in plant growth and development. Despite that miRNAs related to flowering have previously been characterized, miRNAs roles in response to vernalization in Pak-choi (Brassica rapa ssp. chinensis) has never been studied. Here, two sRNA libraries from Brassica rapa leaves (vernalized and non-vernalized plants) were constructed and sequenced. 208 known and 535 novel miRNAs were obtained, of which 20 known and 66 new miRNAs were significantly differentially expressed and considered as vernalization-related miRNAs...

Rapid biosynthesis of abscisic acid (ABA) in the leaf, triggered by a decrease in cell volume, is essential for a functional stomatal response to vapour pressure deficit (VPD) in angiosperms. However, it is not known whether rapid biosynthesis of ABA is triggered in other plant tissues as well. Through the application of external pressure to flower, root and leaf tissues, we test whether a reduction in cell volume can trigger rapid increases in ABA levels across plant body in two species Solanum lycopersicum and Passiflora tarminiana...

The Dof transcription factor (TF) family belongs to a class of plant-specific TFs, and is involved in plant growth, development, and response to abiotic stresses. However, there are only very limited reports on the characterization of Dof TFs in moso bamboo. In the present research, PheDofs showed specific expression profiles based on RNA-seq data analyses. The co-experssion network indicated that PheDof12, PheDof14 and PheDof16 might play vital roles during flower development. Cis-regulatory element analysis of these PheDof genes suggested diverse functions...

High temperature during flowering in rice causes spikelet sterility and is a major threat to rice productivity in tropical and subtropical regions, where hybrid rice development is increasingly contributing to sustain food security. However, the sensitivity of hybrids to increasing temperature and physiological responses in terms of dynamic fertilization processes are unknown. To address these questions, several promising hybrids and inbreds were exposed to control and high day-time temperature (HDT) in Experiment 1 and hybrids having contrasting heat tolerance were selected for Experiment 2 for further physiological investigation under high day and night temperature treatments...

BACKGROUND: It is predicted that climate change may increase the risk of local droughts, with severe consequences for agricultural practices. METHODS: Here we report the influence of drought on alfalfa yields and nutritional composition, based on artificially induced drought conditions during two field experiments. Two types of alfalfa cultivars were compared, Gold Queen and Suntory. The severity and timing of drought periods were varied, and the crop was harvested either early during flowering, or late at full bloom...

CONSTANS (CO) is a master regulator of flowering time, although the mechanisms underlying its role as a transcriptional regulator are not well understood. The DNA-binding domain of CO shares homology with that of NUCLEAR FACTOR YA (NF-YA), a subunit of the CCAAT-binding trimer NF-Y. Recent publications indicate that CO and its rice homolog HEADING DATE 1 (Hd1) form heterotrimers with the histone-fold subunits of NF-Y to efficiently bind promoter elements in the florigen genes. Differences in the DNA-binding specificities of NF-Y and NF-CO can be conceptualized based on our knowledge of the 3D structure of the NF-Y/CCAAT complex...

Lodging is a factor that negatively affects yield, seed quality, and harvest ability in winter rapeseed (Brassica napus L.). In this study, we quantified the lodging-induced yield losses, changes in fatty acid composition, and oil quality in rapeseed under different nitrogen application rates and planting densities. Field experiments were conducted in 2014-2017 for studying the effect of manually-induced lodging angles (0°, 30°, 60°, and 90°), 10, 20 and 30 d post-flowering at different densities and nitrogen application rates...

The temporal expression of the field bean (Dolichos lablab) galactose specific lectin, DLL-II, during germination, post-germination and seed development was evaluated using Native-PAGE followed by activity staining, immunodetection and quantitative Real Time PCR (qPCR). A rapid and steep decline in the polyphenol oxidase (PPO) and hemagglutinating activity during the initial stages of germination, which did not correlate with the slow decline in total protein was observed. During post germination period, PPO and hemagglutination activities were negligible, whereas a rapid resorption of the protein was evident...

Essential oils from flowers and leaves of Grindelia integrifolia DC. were investigated for the first time in terms of chemical composition and antimicrobial activity. The GC-FID/MS analysis allowed for the identification of 58 and 72 volatiles, comprising 92.4 and 90.1% of the oils, respectively. The major components of the flower oil were α-pinene (34.9%) and limonene (13.1%), while myrcene (16.9%), spathulenol (12.3%), β-eudesmol (11.9%) and limonene (10.1%) dominated among the leaf volatiles. The antimicrobial activity, evaluated against 12 selected bacteria and fungus, was found moderate, with the strongest effect of both oils observed against C...

Climate projections forecast more extreme interannual climate variability over time, with an increase in the severity and duration of extreme drought and rainfall events. Based on bioclimatic envelope models, it is projected that changing precipitation patterns will drastically alter the spatial distributions and density of plants and be a primary driver of biodiversity loss. However, many other underlying mechanisms can impact plant vital rates (i.e., survival, growth, and reproduction) and population dynamics...
