Differences between nitrogen-tolerant and nitrogen-susceptible sweetpotato cultivars in photosynthate distribution and transport under different nitrogen conditions. [PDF]

PLoS ONE, 2018
To characterize the differences in photosynthate distribution and transport between nitrogen(N)-tolerant and N-susceptible sweetpotato cultivars under different N conditions, three N levels, including 0 (N0), 120 (N120), and 240 kg ha-1 (N240), were used

Long‐term effects of clear‐cutting forestry on ectomycorrhizal fungi in boreal forest

New Phytologist, EarlyView.
Summary Clear‐cutting is detrimental to ectomycorrhizal fungi in a short time perspective, but long‐term effects on species richness and community composition are uncertain. To evaluate ecological sustainability of rotation forestry, we examined to what extent communities similar to those in old forests develop within the time frame of a rotation ...

Photosynthate partitioning and morphoanatomical aspects of photomorphogenic mutants of tomato

Bioscience Journal, 2013
The aim of this study was to analyze photosynthate partitioning in tomato photomorphogenic mutants at the ends of the vegetative (40 days after emergence [DAE]) and reproductive (69 DAE) stages and to determine its interaction with morphoanatomical ...

Endophytic and ectomycorrhizal, an overlooked dual ecological niche? Insights from natural environments and Russula species

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EcMF) are key components of temperate ecosystems, and recent studies suggest that they can also inhabit non‐EcM plant roots as endophytes. We aimed to (1) provide new evidence of EcMF colonization of non‐EcM hosts, (2) offer direct microscopic confirmation of such endophytism and (3) assess factors influencing ...

P-proteins in Arabidopsis are heteromeric structures involved in rapid sieve tube sealing

Frontiers in Plant Science, 2013
Structural phloem proteins (P-proteins) are characteristic components of the sieve elements in all dicotyledonous and many monocotyledonous angiosperms.

Selective organic matter preservation in "burn-down" turbidites on the Madeira Abyssal Plain [PDF]

, 2003
Oxidized intervals of five organic-rich Madeira Abyssal Plain (MAP) turbidites deposited during the Miocene, Pliocene, and Pleistocene all displayed comparable major loss of total organic carbon (TOC) (84 ± 3.1%) accompanied by a negative isotopic (δ13C)

Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

New Phytologist, EarlyView.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

The ZmCOP1s–ZmCOL3 Module Enhances Late Flowering, Grain Yield and Grain Quality in Maize

Plant Biotechnology Journal, EarlyView.
ABSTRACT Flowering time is a key determinant of yield and regional adaptation in crops and is largely controlled by light signalling. In this study, we identified two maize orthologs of Arabidopsis CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), designated ZmCOP1a and ZmCOP1b, which activate light signalling and reduce plant height. Loss‐of‐function mutants of

Global climate change and tree nutrition: effects of elevated CO2 and temperature [PDF]

, 2010
Although tree nutrition has not been the primary focus of large climate change experiments on trees, we are beginning to understand its links to elevated atmospheric CO2 and temperature changes. This review focuses on the major nutrients, namely N and P,
