Caracterización morfoanatómica en diferentes aspectos de la biología reproductiva del género Gymnocalycium Pfeiff. ex Mittler (cactaceae)

, 2023
Gymnocalycium es el género de Cactaceae más numeroso de Argentina, donde se distribuye alrededor del 80% del total de sus especies. A pesar de ello, poco se han explorado los caracteres morfoanatómicos florales asociados a la biología reproductiva del ...

Influence of change in the proportion of H1 histone variants on microsporogenesis and development of male gametophyte in transgenic plants of tobacco (Nicotiana tabacum L.)

Acta Societatis Botanicorum Poloniae, 2011
As continuation of investigations in to the mechanism of the role of the H1 histone, which is a crucial protein component chromosomes of all eukaryotes, transgenic tobacco plants with different levels of the H1 histone variants were examined. Tobacco has

OsALKBH9‐mediated m6A demethylation regulates tapetal PCD and pollen exine accumulation in rice

Plant Biotechnology Journal, Volume 22, Issue 9, Page 2410-2423, September 2024.
Summary The N6‐methyladenosine (m6A) mRNA modification is crucial for plant development and stress responses. In rice, the male sterility resulting from the deficiency of OsFIP37, a core component of m6A methyltransferase complex, emphasizes the significant role of m6A in male fertility. m6A is reversible and can be removed by m6A demethylases. However,

Microsporogenesis and the biosynthesis of floral small interfering RNAs in coffee have a unique pattern among eudicots, suggesting a sensitivity to climate changes

Plant Direct
Recently, the siRNAs pathways, and especially reproductive phasiRNAs, have attracted attention in eudicots since their biological roles are still unknown and their biogenesis took different evolutionary pathways compared to monocots.

SCSBRS126 Dueto: irrigated rice variety resilient to cold and heat at reproductive stage

Crop Breeding and Applied Biotechnology, 2023
SCSBRS126 Dueto is a late-maturing high yield performing cultivar released by Epagri/Embrapa/Udesc. It has high tillering capacity, but poor resistance to lodging, medium resistance to blast, with long, slender grains and good sensory/cooking traits, and

High-temperature injury and auxin biosynthesis in microsporogenesis.

Frontiers in Plant Science, 2013
Plant reproductive development is more sensitive than vegetative growth to many environmental stresses. With global warming, in particular, plant high temperature injury is becoming an increasingly serious problem.

Heat shock protein 101 safeguards meiotic thermotolerance of male germlines in rice and Arabidopsis

Crop Journal
Heat stress induces severe meiotic defects in plants, leading to significant male sterility and substantial yield losses in crops. However, few genes involved in meiotic thermotolerance have been characterized.

Polyamines in pollen: from microsporogenesis to fertilization

Frontiers in Plant Science, 2016
The entire pollen life span is driven by polyamine (PA) homeostasis, achieved through fine regulation of their biosynthesis, oxidation, conjugation, compartmentalization, uptake, and release.
