Pollen: A Potential Explant for Genetic Transformation in Wheat (Triticum aestivum L.)

Agronomy, 2022
The use of biotechnology for the genetic improvement of wheat (Triticum aestivum L.) has been hampered by its recalcitrance to standard transformation and regeneration protocols. Male gametes present a potentially useful option for introducing gene edits

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.

The OsWRKY15‐OsSUT3 Regulatory Module Enhances Rice Pollen Fertility by Mediating Sucrose Allocation to Anthers

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sucrose transport and starch accumulation are crucial carbohydrate metabolic processes in rice, playing essential roles during late pollen development to ensure pollen maturation, fertility and high grain production. However, the molecular mechanisms regulating sucrose transport and starch accumulation during rice pollen development remain ...

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.

The Arabidopsis KINβγ Subunit of the SnRK1 Complex Regulates Pollen Hydration on the Stigma by Mediating the Level of Reactive Oxygen Species in Pollen.

PLoS Genetics, 2016
Pollen-stigma interactions are essential for pollen germination. The highly regulated process of pollen germination includes pollen adhesion, hydration, and germination on the stigma. However, the internal signaling of pollen that regulates pollen-stigma

Pollen Viability, Germination and Tube Elongation Responses to Heat Stress During the Reproductive Stage in Maize

Journal of Agronomy and Crop Science, Volume 212, Issue 5, September 2026.
ABSTRACT Climate change‐induced heat stress increasingly threatens crop production, particularly when high temperatures occur during the sensitive flowering stage. In maize, successful fertilization depends on viable pollen, successful pollen germination and subsequent pollen tube elongation reaching the ovule.
