Decomposition analysis on soybean productivity increase under elevated CO2 using 3-D canopy model reveals synergestic ef...
Published in Annals of botany
Understanding how climate change influences crop productivity helps in identifying new options to increase crop productivity. Soybean is the most important dicotyledonous seed crop in terms of planting area. Although the impacts of elevated atmospheric [CO2] on soybean physiology, growth and biomass accumulation have been studied extensively, the c...
Contrasting phenotypes emerging from stable rules: A model based on self-regulated control loops captures the dynamics o...
Published in Annals of botany
The dynamics of plant architecture is a central aspect of plant and crop models. Most models assume that whole shoot development is orchestrated by the leaf appearance rate, which follows a thermal time schedule. However, leaf appearance actually results from leaf extension and taking it as an input hampers our ability to understand shoot construct...
Seed coat development in explosively dispersed seeds of Cardamine hirsuta.
Published in Annals of botany
Seeds are dispersed by explosive coiling of the fruit valves in Cardamine hirsuta. This rapid coiling launches the small seeds on ballistic trajectories to spread over a 2 m radius around the parent plant. The seed surface interacts with both the coiling fruit valve during launch and subsequently with the air during flight. We aim to identify featu...
Identification of salicylic acid-independent responses in an Arabidopsis phosphatidylinositol 4-kinase beta double mutan...
...Published in Annals of botany
We have recently shown that an Arabidopsis thaliana double mutant of type III phosphatidylinositol-4-kinases (PI4Ks), pi4kβ1β2, constitutively accumulated a high level of salicylic acid (SA). By crossing this pi4kβ1β2 double mutant with mutants impaired in SA synthesis (such as sid2 impaired in isochorismate synthase) or transduction, we demonstrat...
Extensin arabinosylation is involved in root response to elicitors and limits oomycete colonization.
...Published in Annals of botany
Extensins are hydroxyproline-rich glycoproteins thought to strengthen the plant cell wall, one of the first barriers against pathogens, through intra- and intermolecular cross-links. The glycan moiety of extensins is believed to confer the correct structural conformation to the glycoprotein, leading to self-assembly within the cell wall that helps ...
The SAUR41 subfamily of SMALL AUXIN UP RNA genes is abscisic acid inducible to modulate cell expansion and salt toleranc...
...Published in Annals of botany
Most primary auxin response genes are classified into three families: AUX/IAA, GH3 and SAUR genes. Few studies have been conducted on Arabidopsis thaliana SAUR genes, possibly due to genetic redundancy among different subfamily members. Data mining on arabidopsis transcriptional profiles indicates that the SAUR41 subfamily members of SMALL AUXIN UP...
Overexpression of PtHMGR enhances drought and salt tolerance of poplar.
Published in Annals of botany
Soil salinization and aridification are swiftly engulfing the limited land resources on which humans depend, restricting agricultural production. Hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) is important in the biosynthesis of terpenoids, which are involved in plant growth, development and responses to environmental stresses. This study aim...
Using the CODIT model to explain secondary metabolites of xylem in defence systems of temperate trees against decay fung...
Published in Annals of botany
In trees, secondary metabolites (SMs) are essential for determining the effectiveness of defence systems against fungi and why defences are sometimes breached. Using the CODIT model (Compartmentalization of Damage/Dysfunction in Trees), we explain defence processes at the cellular level. CODIT is a highly compartmented defence system that relies on...
Exploring evolutionary theories of plant defence investment using field populations of the deadly carrot.
Published in Annals of botany
There are a number of disparate models predicting variation in plant chemical defences between species, and within a single species over space and time. These can give conflicting predictions. Here we review a number of these theories, before assessing their power to predict the spatial-temporal variation of thapsigargins between and within populat...
