Symbiosis‐associated UMAMIT transporters required for establishing efficient nitrogen fixation in Medicago truncatula

New Phytologist, EarlyView.
Summary To address a critical gap in understanding amino acid transport in legume–Rhizobium symbiosis, we investigated the role of symbiosis‐associated USUALLY MULTIPLE ACIDS MOVE IN AND OUT TRANSPORTERS (UMAMITs) in Medicago truncatula nodulation.

Strain, procedures, and tools for reproducible genetic transformation and genome editing of the emerging plant model Spirodela polyrhiza

New Phytologist, EarlyView.
Summary Duckweeds (Lemnaceae) have excellent potential for fundamental and applied research due to ease of cultivation, small size, and continuous fast clonal growth. However, their usage as model organisms and platforms for biotechnological applications is often limited by the lack of universal genetic manipulation methods necessary for transgene ...

MITOGEN‐ACTIVATED PROTEIN KINASE9 fine‐tunes hypoxia signaling by phosphorylating ERF‐VII transcription factors in Arabidopsis

New Phytologist, EarlyView.
Summary In plants, hypoxia sensing is controlled by the stabilization of group VII ethylene response factors (ERF‐VIIs), which are post‐translationally activated by the mitogen‐activated protein kinases (MAPKs) MPK3 and MPK6. However, how plants fine‐tune the MPK3/MPK6‐mediated phosphorylation of ERF‐VIIs to maintain cellular homeostasis remains ...

When wuthering winds create fluttering fields: structural and biomechanical properties determine canopy light fluctuation properties of 10 wheat cultivars

New Phytologist, EarlyView.
Summary Wind‐driven plant movement generates rapid light fluctuations (windflecks), which can impact canopy photosynthesis. Targeting crop photosynthesis in dynamic light provides a potential path towards boosting yield. Here, we quantified how plant architecture and biomechanics modulate such windflecks across 10 high‐yielding cultivars of winter ...

Identification of molecular markers associated to new sources of resistance to the root-knot nematode in cotton : S02T04 [PDF]

, 2013
The root-knot nematode (RKN) Meloidogyne incognita is a major constraint in cotton (Gossypium hirsutum L.) production in numerous countries. Control of RKN has been hampered by the lack of options for crop rotation and even more, by the lack of high ...

Epigenetic regulation of mycorrhizal symbioses: from plastic responses to transgenerational legacies

New Phytologist, EarlyView.
Summary Mycorrhizal symbioses represent one of the most widespread and ecologically significant plant–microbe interactions, shaping plant nutrition, stress resilience, and ecosystem functioning. Beyond their role in nutrient exchange and systemic defense, growing evidence suggests that these symbioses also influence plant plasticity within and across ...

Avaliação da germinação e dormência de sementes de arroz vermelho e branco

Revista de Ciências Agroveterinárias, 2014
As sementes de arroz branco possuem dormência, porém de intensidade menor que as de arroz vermelho. Entretanto, já foram observados alguns genótipos de arroz vermelho com dormência de intensidade semelhante à de sementes de arroz branco.
