The effects of rising atmospheric carbon dioxide on shoot-root nitrogen and water signaling. [PDF]
, 2013 Terrestrial higher plants are composed of roots and shoots, distinct organs that conduct complementary functions in dissimilar environments. For example, roots are responsible for acquiring water and nutrients such as inorganic nitrogen from the soil ...

Effect of Dicamba and 2,4 dichlorophenoxiacetic acid on sugarcane somatic embryogenesis
Revista Colombiana de Biotecnología, 2015 In order to conserve sugarcane germplasm, produce microbial disease-free material, detect resistance to diseases and pests, etc., in vitro propagation of sugarcane has been established in many commercial varieties. In this sense, the aim of this work was

A mathematical model integrates diverging PXY and MP interactions in cambium development [PDF]
, 2022 The cambium is a meristematic tissue in plant stems. Here, cell divisions occur that are required for radial growth of plant stems. Daughters of cell divisions within the cambium differentiate into woody xylem cells towards the inside of the stem, or phloem towards the outside. As such, a pattern of xylem-cambium-phloem is present along the radial axis

Artificial Seed Production from Encapsulated Microshoots of Cauliflower (Brassica oleraceae var botrytis) [PDF]
, 2012 A cost effective protocol for the production of cauliflower microshoots suitable for encapsulation was designed. Microshoots were encapsulated in sodium chloride matrices. The use of 2% of sodium alginate and 15 g/L of dehydrate calcium chloride produced

The Arabidopsis Book, 2014 lndole-3-acetic acid (IAA), the most important natural auxin in plants, is mainly synthesized from the amino acid tryptophan (Trp). Recent genetic and biochemical studies in Arabidopsis have unambiguously established the first complete Trp-dependent auxin biosynthesis pathway.

Auxin and Cellular Elongation [PDF]
Plant Physiology, 2016 Auxin is a crucial growth regulator in plants. However, a comprehensive understanding of how auxin induces cell expansion is perplexing, because auxin acts in a concentration- and cell type-dependent manner. Consequently, it is desirable to focus on certain cell types to exemplify the underlying growth mechanisms.

High auxin stimulates callus through SDG8‐mediated histone H3K36 methylation in Arabidopsis
Journal of Integrative Plant Biology, Volume 64, Issue 12, Page 2425-2437, December 2022., 2022 Callus induction, which results in cell fate transition, is considered as first and key step for plant regeneration. During the process, high auxin activates SET DOMAIN GROUP8 (SDG8) expression through TIR1/AFB‐based transcriptional regulation. SDG8 then deposits H3K36me3 modifications on the loci of callus‐related and cell proliferation‐related genes,

ACS Chemical Biology, 2007 Indole-3-acetic acid (IAA or auxin) is essential throughout the life cycle of a plant. It controls diverse cellular processes, including gene expression. The hormone is perceived by a ubiquitin protein ligase (E3) and triggers the rapid destruction of repressors, called Aux/IAA proteins.
