Terniopsis chanthaburiensis (Podostemaceae), a new record for China and its complete plastid genome

Nordic Journal of Botany, EarlyView.
The genus Terniopsis consists of plants that have not been thoroughly studied, with many species remaining taxonomically unresolved. In this study, Terniopsis chanthaburiensis is reported as a new record of China based on morphological traits. Then, we assembled and annotated its chloroplast genome based on genome skimming data.

Induction of Semi-Dwarf Trait to a Three Pistil Tall Mutant Through Breeding With Increased Grain Numbers in Wheat

Frontiers in Genetics, 2022
Multi-ovary wheat (three pistil) is a unique germplasm for the seed production of hybrid wheat. The purpose of the present study was to transfer the multi-ovary trait to semi-dwarf plants to increase the production of grains in wheat crops.

A pistil-expressed pectin methylesterase confers cross-incompatibility between strains of Zea mays

Nature Communications, 2019
A central problem in speciation is the origin and mechanisms of reproductive barriers that block gene flow between sympatric populations. Wind-pollinated plant species that flower in synchrony with one another rely on post-pollination interactions to ...

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

Nordic Journal of Botany, EarlyView.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

Functional analysis of SlNCED1 in pistil development and fruit set in tomato (Solanum lycopersicum L.)

Scientific Reports, 2019
Abscisic acid (ABA) is an important regulator of many plant developmental processes, although its regulation in the pistil during anthesis is unclear. We investigated the role of 9-cis-epoxycarotenoid dioxygenase (SlNCED1), a key ABA biosynthesis enzyme,

The effect of sheltered load on reproduction in Solanum carolinense, a species with variable self-incompatibility [PDF]

, 2009
In previous studies, we have investigated the strength of self-incompatibility (SI) in Solanum carolinense, a highly successful weed with a fully functional SI system that inhabits early successional and other disturbed habitats.

Proteomics Advances in the Understanding of Pollen–Pistil Interactions

Proteomes, 2014
The first key point to the successful pollination and fertilization in plants is the pollen-pistil interaction, referring to the cellular and molecular levels, which mainly involve the haploid pollen and the diploid pistil.

Pollen-pistil interactions and the endomembrane system [PDF]

Journal of Experimental Botany, 2010
The endomembrane system offers many potential points where plant mating can be effectively controlled. This results from two basic features of angiosperm reproduction: the requirement for pollen tubes to pass through sporophytic tissues to gain access to ovules and the physiology of pollen tube growth that provides it with the capacity to do so.
