Morphology and viability of pollen grains from passion fruit species (Passiflora spp.)

Acta Botânica Brasílica, 2013
The characterization and viability of pollen grains are useful tools to guide crosses in breeding programs. The objective of this study was to describe the morphological patterns and viability of pollen grains from five accessions of Passiflora edulis f.

ERF Transcription Factor NaERFIDOG Regulates JA‐Induced Defence and Growth Inhibition in Nicotiana attenuata Upon Alternaria alternata Infection

Plant Biotechnology Journal, EarlyView.
ABSTRACT Jasmonate (JA) regulates defence responses in plants. However, JA‐induced defence often results in growth inhibition. This process is largely mediated by MYC2, the master regulator of JA signalling. Nevertheless, the underlying molecular mechanisms have not yet been fully uncovered.

GhTTLL12 Coordinates With Transcriptional Regulators GhMML3 and GhMYB86 to Orchestrate Cotton Fibre Development Through Modulating Microtubule Dynamics

Plant Biotechnology Journal, EarlyView.
ABSTRACT Microtubules (MTs) are crucial for cell division, growth, development and morphogenesis in plants. Cotton fibres are single‐celled trichomes that originate from the epidermal cells of the ovule, making them an excellent model for studying plant cell differentiation and rapid elongation.

Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

Plant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

Root trait dynamics of historical canola varieties under low and high nitrogen supply

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Nitrogen fertilizer is a major input cost in crop production, making it crucial to enhance nitrogen use efficiency (NUE) to reduce fertilizer dependence without compromising yields. Root system architecture (RSA) is a key determinant of nutrient acquisition, particularly under nutrient‐limited conditions.

Weak Static and Extremely Low Frequency Magnetic Fields Affect In Vitro Pollen Germination

The Scientific World Journal, 2011
This study concerns the effects of a weak static magnetic field (MF) at 10 μT oriented downward, combined with a 16-Hz sinusoidal MF (10 μT), on in vitro pollen germination of kiwifruit (Actinidia deliciosa).
