Above-ground parts of white grapevine Vitis vinifera cv. Furmint share core members of the fungal microbiome.

Environ Microbiol Rep 2021 May 5. Epub 2021 May 5.

Department of Plant Anatomy, Institute of Biology, Eötvös Loránd University, Pázmány Péter sétány 1/C, Budapest, 1117, Hungary.

Grapevine (Vitis vinifera) is a reservoir of fungal endophytes that may affect its growth, health status and grape production. Although there is growing interest in comparing fungal communities of mainly red grape varieties across various factors using only high-throughput sequencing, the small-scale mycobiome variations in geographically close vineyards need further examination. We aimed to characterize the fungal microbiome of the above-ground tissues of V. Read More

Is "Esterhazy II", an Old Walnut Variety in the Hungarian Gene Bank, the Original Genotype?

Plants (Basel) 2021 Apr 23;10(5). Epub 2021 Apr 23.

Forest Research Institute, University of Sopron, Várkerület 30/A, 9600 Sárvár, Hungary.

The old walnut ( L.) genotype called "Esterhazy II" was well-known in the Austro-Hungarian Monarchy before World War II, and it can still be found in the Austrian, German and Swiss backyard gardens today. Unfortunately, nowadays, vegetatively propagated progenies of the original "Esterhazy II" are not available anymore around the world because walnut grafting started later than this genotype had become well-known.

Genetic Relationships Among Physiological Processes, Phenology, and Grain Yield Offer an Insight Into the Development of New Cultivars in Soybean ( L. Merr).

Front Plant Sci 2021 9;12:651241. Epub 2021 Apr 9.

Department of Agronomy, Purdue University, West Lafayette, IN, United States.

Soybean grain yield has steadily increased during the last century because of enhanced cultivars and better agronomic practices. Increases in the total biomass, shorter cultivars, late maturity, and extended seed-filling period are frequently reported as main contributors for better soybean performance. However, there are still processes associated with crop physiology to be improved. Read More

Improved performance of the eastern spruce budworm on black spruce as warming temperatures disrupt phenological defences.

Glob Chang Biol 2021 Apr 19. Epub 2021 Apr 19.

Natural Resources Canada, Canadian Forest Service, Sainte-Foy, QC, Canada.

Phenological shifts, induced by global warming, can lead to mismatch between closely interacting species. The eastern spruce budworm, Choristoneura fumiferana, an important outbreaking insect defoliator in North America, mainly feeds on balsam fir, Abies balsamea, which has historically been well synchronized with the insect. But as climate change pushes the northern range limit of the budworm further north into the boreal forest, the highly valuable black spruce, Picea mariana, historically protected against the budworm by its late budburst phenology, is suffering increased defoliation during the current outbreak.

Ethylene involvement in the regulation of heat stress tolerance in plants.

Plant Cell Rep 2021 Mar 13. Epub 2021 Mar 13.

Department of Botany, Jamia Hamdard, New Delhi, India.

Because of the rise in global temperature, heat stress has become a major concern for crop production. Heat stress deteriorates plant productivity and alters phenological and physiological responses that aid in precise monitoring and sensing of mild-to-severe transient heat stress. Plants have evolved several sophisticated mechanisms including hormone-signaling pathways to sense heat stimuli and acquire heat stress tolerance. Read More

Foliar application of 3-hydroxy-4-pyridinone Fe-chelate [Fe(mpp) ] induces responses at the root level amending iron deficiency chlorosis in soybean.

Physiol Plant 2021 Feb 25. Epub 2021 Feb 25.

REQUIMTE, LAQV, Instituto de Ciências Biomédicas de Abel Salazar, Universidade do Porto, Porto, Portugal.

Iron (Fe) deficiency chlorosis (IDC) affects the growth of several crops, especially when growing in alkaline soils. The application of synthetic Fe-chelates is one of the most commonly used strategies in IDC amendment, despite their associated negative environmental impacts. In a previous work, the Fe-chelate tris(3-hydroxy-1-(H)-2-methyl-4-pyridinonate) iron(III) [Fe(mpp) ] has shown great potential for alleviating IDC in soybean (Glycine max) in the early stages of plant development under hydroponic conditions.

Department of Plant Biology and Ecology, University of the Basque Country (UPV/EHU), Apdo., Bilbao, Spain.

Nitrate (NO3-) and ammonium (NH4+) are the main inorganic nitrogen sources available to plants. However, exclusive ammonium nutrition may lead to stress characterized by growth inhibition, generally associated with a profound metabolic reprogramming. In this work, we investigated how metabolism adapts according to leaf position in the vertical axis of tomato (Solanum lycopersicum cv. Read More

Larval tolerance to food limitation is stronger in an exotic barnacle than in its native competitor.

Zoology (Jena) 2021 Apr 17;145:125891. Epub 2020 Dec 17.

School of Ocean Sciences, Bangor University, Askew Street, LL59 5AB, Anglesey, Wales, United Kingdom; Marine Station of Helgoland, Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Ostkaje 1118, DE-27498, Helgoland, Germany. Electronic address:

A critical question in marine ecology is understanding how organisms will cope with environmental conditions under climate change. Increasing temperatures not only have a direct effect on marine organisms but may also lead to food limitation through for example trophic mismatches, or by the increased metabolic demands imposed by developing at high temperatures. Using barnacles from a population of North Wales, we studied the combined effect of temperature and food density on the survival, settlement success, developmental time and body size of larvae of the native barnacle Semibalanus balanoides and its exotic competitor, the barnacle Austrominius modestus.

The potential of resilient carbon dynamics for stabilizing crop reproductive development and productivity during heat stress.

Plant Cell Environ 2021 Feb 4. Epub 2021 Feb 4.

Division of Plant & Crop Science, University of Nottingham, Leicestershire, UK.

Impaired carbon metabolism and reproductive development constrain crop productivity during heat stress. Reproductive development is energy intensive, and its requirement for respiratory substrates rises as associated metabolism increases with temperature. Understanding how these processes are integrated and the extent to which they contribute to the maintenance of yield during and following periods of elevated temperatures is important for developing climate-resilient crops.
