The role of auxin in nitrogen-modulated shoot branching. | LitMetric

The role of auxin in nitrogen-modulated shoot branching.

Published: April 2021

Shoot branching is determined by axillary bud formation and outgrowth and remains one of the most variable determinants of yield in many crops. Plant nitrogen (N) acquired mainly in the forms of nitrate and ammonium from soil, dominates plant development, and high-yield crop production relies heavily on N fertilization. In this review, the regulation of axillary bud outgrowth by N availability and forms is summarized in plant species. The mechanisms of auxin function in this process have been well characterized and reviewed, while recent literature has highlighted that auxin export from a bud plays a critical role in N-modulating this process.

Branching architecture affects genetic diversity within an individual tree.

J Theor Biol

March 2025

Department of Biology, Faculty of Science, Kyushu University, 744 Motooka, Nishi-ku, Fukuoka 819-0395, Japan.

While a tree grows over many years, somatic mutations accumulate and form genetic variation among branches within an individual. Trees can transmit such mutations to subsequent generations, potentially enhancing the genetic diversity of the population. We study a mathematical model to understand the relationship between within-individual genetic variation and branching architecture.

Stable plastid transformation in kiwifruit ().

aBIOTECH

March 2025

State Key Laboratory of Biocatalysis and Enzyme Engineering, School of Life Sciences, Hubei University, Wuhan, 430062 China.

Unlabelled: Plastid transformation offers valuable benefits in plant biotechnology, such as high-level transgene expression and the absence of gene silencing. Here we describe the first protocol of a plastid transformation system for a woody vine (liana) kiwifruit (). The transgenic DNA carries a spectinomycin-resistance gene () cassette and a green fluorescent protein () reporter gene cassette, flanked by two adjacent kiwifruit plastid genome sequences, thereby allowing targeted insertion between the and genes.

Background And Aims: With ongoing climate change, the impact of droughts of increasing intensity on forest functioning is of critical concern. While the adverse effects of drought on tree secondary growth have been largely documented both at the tree and stand scales, our understanding of how primary growth morphological traits, which control crown development, respond to drought remains limited - especially in the long term.

Methods: Based on 14 years of monitoring of four primary growth morphological traits (e.

Characterization of nitrate use efficiency in tea plant () based on leaf chlorate sensitivity.

Hortic Res

April 2025

Key Laboratory of Biology, Genetics and breeding of Special Economic Animals and Plants, Ministry of Agriculture and Rural Affairs, 310008, No.9 Meiling South Road, Hangzhou, Xihu District, Zhejiang ProvinceP.R.China.

Nitrate (NO ), a key form of inorganic nitrogen (N) in soils, is typically lost in tea gardens through leaching. However, NO utilization efficiency (NiUE) and its characteristic mechanism in tea plants remain unclear. This study screened contrastive genotypes of NiUE using leaf chlorate sensitivity and explored the potential genes that regulate this process.
