Polymorphisms and gene expression in the almond IGT family are not correlated to variability in growth habit in major commercial almond cultivars.

PLoS ONE, 2021
Almond breeding programs aimed at selecting cultivars adapted to intensive orchards have recently focused on the optimization of tree architecture. This multifactorial trait is defined by numerous components controlled by processes such as hormonal ...

Involvement of the Vacuoles of the Endodermis in the Early Process of Shoot Gravitropism in Arabidopsis [PDF]

The Plant Cell, 2002
The endodermal cells of the shoot are thought to be the gravity-sensing cells in Arabidopsis. The amyloplasts in the endodermis that sediment in the direction of gravity may act as statoliths. Endodermis-specific expression of SGR2 and ZIG using the SCR promoter could complement the abnormal shoot gravitropism of the sgr2 and zig mutants, respectively.

Cellular and physiological functions of SGR family in gravitropic response in higher plants

Journal of Advanced Research
Background: In plants, gravity directs bidirectional growth; it specifies upward growth of shoots and downward growth of roots. Due to gravity, roots establish robust anchorage and shoot, which enables to photosynthesize.

Overexpression of the protein phosphatase 2A regulatory subunit a gene ZmPP2AA1 improves low phosphate tolerance by remodeling the root system architecture of maize. [PDF]

PLoS ONE, 2017
Phosphate (Pi) limitation is a constraint for plant growth and development in many natural and agricultural ecosystems. In this study, a gene encoding Zea mays L.

Gibberellins and Gravitropism in Maize Shoots [PDF]

Plant Physiology, 1987
[3H]Gibberellin A20 (GA20) of high specific radioactivity (49.9 gigabecquerel per millimole) was applied equilaterally in a ring of microdrops to the internodal pulvinus of shoots of 3-week-old gravistimulated and vertical normal maize (Zea mays L.), and to a pleiogravitropic (prostrate) maize mutant, lazy (la).

Interaction with gravitropism, reversibility and lateral movements of phototropically stimulated potato shoots [PDF]

Journal of Plant Research, 2016
Phototropic (PT) and gravitropic (GT) bending are the two major tropic movements that determine the spatial position of potato shoots. We studied PT bending of potato plantlets grown under long-day photoperiods in several prearranged position setups providing different interactions with the GT response.

Ammonium inhibits primary root growth by reducing the length of meristem and elongation zone and decreasing elemental expansion rate in the root apex in Arabidopsis thaliana.

PLoS ONE, 2013
The inhibitory effect of ammonium on primary root growth has been well documented; however the underlying physiological and molecular mechanisms are still controversial. To avoid ammonium toxicity to shoot growth, we used a vertical two-layer split plate

Root Cap Cuticles Confer a Transient, Penetration‐Optimised Phase During Early Seedling Establishment

Plant, Cell &Environment, EarlyView.
ABSTRACT Roots emerging from seeds encounter substantial mechanical resistance during soil entry. A transient root cap cuticle (RCC) forms early in development, yet its contribution to root tip function during this mechanically challenging transition remains unclear.

Regulation of tiller angle by gravity-sensing genes in rice

Crop Journal
Endodermal cells and starch-accumulating amyloplasts are well-known gravity sensors initiating shoot gravitropism in Arabidopsis thaliana. The transcription factors SHR and SGR1 regulate endodermal cell formation, while PGM has been demonstrated to ...
