Molecular factors involved in the formation of secondary vascular tissues and lignification in higher plants [PDF]

open access: yes, 2003
The formation of secondary vascular tissues involves complex processes and many steps, a number of which have been examined in detail in this study. A novel CuZn-SOD, with a high pI and thus denoted hipI-SOD, was identified and characterized in Pinus ...

GeARF5/GeIAA33‐GeSWEET14 module balances the secondary metabolic biosynthesis to increase the yield and quality in Gastrodia elata

open access: yesJournal of Integrative Plant Biology, EarlyView.
Auxin signaling regulates the formation of vegetative propagation corms in Gastrodia elata by regulating sugar‐acid interconversion, which in turn regulates polysaccharide and starch biosynthesis as well as biosynthesis of the bioactive metabolite gastrodin.

The maize mitogen‐activated protein kinase kinase kinase gene ZmMAPKKK45 is associated with multiple disease resistance

open access: yesNew Phytologist, EarlyView.
Summary Southern leaf blight (SLB), caused by the necrotrophic fungus Cochliobolus heterostrophus, is a major foliar disease of maize (Zea mays) world‐wide. A genome‐wide association study was performed to dissect the genetic basis of SLB resistance in maize. Functional validation was performed using mutant and transgenic analyses.

Low abundance of phytophagous nematodes under invasive exotic Pinus elliottii – enemy release and plant–soil feedbacks

open access: yesNew Phytologist, EarlyView.
Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

Fruit respiration: putting alternative pathways into perspective

open access: yesNew Phytologist, EarlyView.
Summary Over the past century, research has significantly advanced our understanding of fruit respiration, from (eco)physiological processes to molecular mechanisms. This review focuses on the functional relevance and regulatory roles of mitochondrial alternative respiratory pathways (ARPs) during fruit growth and ripening.

Root tip excision‐induced exodermis lignification impacts lateral root emergence in Brachypodium distachyon

open access: yesNew Phytologist, EarlyView.
Summary The mechanisms controlling lateral root emergence in monocots, particularly the role of the exodermis, are poorly understood. We investigated how natural variation in the Brachypodium distachyon stress response shapes root system architecture by modulating cell wall dynamics.

Quiescence of postharvest pathogens: a fungal inhibition process or an immune response of the unripe host fruit?

open access: yesNew Phytologist, EarlyView.
Summary Postharvest pathogens can infect fresh produce both before and after harvest, by direct or wound‐enhanced penetration, remaining quiescent until ripening. Biotrophic‐like postharvest pathogens persist beneath host cells and can remain in a state of quiescence.

Metabolo‐Transcriptomics Analyses Reveal Alfalfa Adaptation to Combined Saline‐Alkali and Low‐Temperature Stress in the Field

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Alfalfa (Medicago sativa L.) is known as the ‘King of Forage’ because of its high protein content and excellent palatability. Alfalfa productivity is adversely affected in cold regions with saline‐alkali soils. However, the mechanisms underlying the response of alfalfa to combined saline‐alkali and low‐temperature stress under field conditions
