Optimization of In Vitro Pecan Pollen Germination [PDF]

open access: yesHortScience, 2011
Storage of pollen from 1 year to the next is often needed to enable desired crosses to be made in a pecan [ Carya illinoinensis (Wangenh.) K. Koch] breeding program. Stored pollen is usually tested for viability through the use of in vitro germination tests.

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

open access: yesAllergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Studies on in vitro manipulation of male and female reproductive systems of flowering plants [PDF]

open access: yes, 1993
The overall aim of this research project is to investigate the possibility of using pollen as a vector for transporting extracellular substances to the site of gamete fusion in the embryo sac.

Pollen production, viability and in vitro pollen germination of different litchi (Litchi chinensis) genotypes

open access: yesThe Indian Journal of Agricultural Sciences, 2018
Litchi (Litchi chinensis Sonn.) is one of the important commercial fruits of the subtropical region. Its short flowering period couple with narrow genetic base serves as the major constraints in litchi genetic improvement.

De novo stolon organogenesis in potato leaf callus elicited by Agrobacterium tumefaciens stimulus

open access: yesJournal of Integrative Plant Biology, EarlyView.
Agrobacterium tumefaciens triggers stolon regeneration from potato leaf callus independent of T‐DNA insertion, suggesting a strategy to reprogram callus identity and expand the potential of tissue regeneration. ABSTRACT Plant cells can undergo cellular reprogramming, enabling pluripotent callus formation from excised leaves.

Pollen physiology and fertilisation in Vicia Faba L [PDF]

open access: yes, 1990
In many legume crop species, early-formed fruits or those located closest to the photosynthate are more likely to mature than other fruits. This is so in the Vicia faba crop.

Pentatricopeptide repeat proteins in crops: Advances in functional mechanisms and breeding applications

open access: yesJournal of Integrative Plant Biology, EarlyView.
Pentatricopeptide repeat proteins coordinate nucleus‐organelle communication by modulating RNA metabolism within chloroplasts and mitochondria. This review highlights how they control critical processes like photosynthesis, seed development, fertility restoration, and stress survival in crops, and explores their potential as programmable tools for RNA ...

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

open access: yesAgronomy, 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

HSP101‐encoding NEO‐TETRAPLOID RICE FERTILITY GENE 1 regulates tapetum development through interaction with SAPK2 in polyploid rice

open access: yesJournal of Integrative Plant Biology, EarlyView.
In neo‐tetraploid rice, the NTRF1–SAPK2 heat shock protein–kinase module coordinates abscisic acid signaling with reactive oxygen species homeostasis to ensure timely tapetal programmed cell death and subsequent pollen maturation, providing a resource for the genetic improvement of polyploid rice.
