The Long Journey of Pollen Tube in the Pistil
In non-cleistogamous plants, the male gametophyte, the pollen grain is immotile and exploits various agents, such as pollinators, wind, and even water, to arrive to a receptive stigma. The complex process of pollination involves a tubular structure, i.e.,

Friables and embryogenic callus induction from embryo, ovule and style of citrus rootstocks : [P97] [PDF]
The incorporation of new technologies such as in vitro selection and protoplast fusion methods into citrus improvement programs offers new opportunities to facilitate, expedite, and fully utilize germplasm variability for both scion and rootstock ...

The Cinderella tree, Quillaja saponaria – A soap story
Our current understanding of plants has been shaped by the entwining of different cultures. The Chilean soapbark tree, traditionally valued as a source of natural soap, was shown by serendipitous research in France in the 1900s to produce compounds that can boost the immune response to vaccines.

The experiment was carried out in a three unheated plastic tunnels in 1998-2000. The aim of this study was to estimate the effects of flower's heterostyly and two methods of flower pollination (self-pollination and using bumble-bee) as well as flower ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract It is widely documented that many crops depend on animal—and primarily insect—pollination, but the degree to which pollinators limit yield in comparison with other factors is poorly understood.

Molecular Research Progress on Gametophytic Self-Incompatibility in Rosaceae Species
Self-incompatibility (SI) is a complex mechanism that prevents plants from self-fertilizing to preserve and promote genetic variability. The angiosperm species have developed two different SI systems, the sporophytic (SSI) and the gametophytic (GSI ...

ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.

The wheat mutant line three-pistil (TP) exhibits three pistils per floret. As TP normally has two or three seeds in each of the florets on the same spike, there is the possibility of increasing the number of grains per spike.

THESEUS1 is a component of the receptor complex for establishing polytubey block in Arabidopsis
THESEUS1 (THE1) is a component of the CrRLK1L‐RALF signaling complex specifically responsible for establishing the polytubey block at the Arabidopsis septum. Genetic and biochemical analyses demonstrate that THE1, together with FERONIA, ANJ and HERK1, forms a receptor complex that senses pollen tube‐derived RALF peptides, thereby establishing a barrier
