Role of autophagy in plant growth and adaptation to salt stress.

Planta

January 2025

Biological and Geological Sciences Department, Faculty of Education, Ain Shams University, Cairo, 11341, Egypt.

Under salt stress, autophagy regulates ionic balance, scavenges ROS, and supports nutrient remobilization, thereby alleviating osmotic and oxidative damage. Salt stress is a major environmental challenge that significantly impacts plant growth and agricultural productivity by disrupting nutrient balance, inducing osmotic stress, and causing the accumulation of toxic ions like Na. Autophagy, a key cellular degradation and recycling pathway, plays a critical role in enhancing plant salt tolerance by maintaining cellular homeostasis and mitigating stress-induced damage.

Background: Glyphosate is an extensively employed herbicide in agriculture, specifically for sugarcane cultivation. The situation is different with the extensive physiological and genetic effects exerted by this herbicide on a range of plant species, including sugarcane, whose model basis is still poorly characterized, although its primary mode of action, which acts on the EPSPS enzyme in the shikimic acid pathway, is completely elucidated. The current study was aimed at investigating the stability of glyphosate formulation, molecular interactions of glyphosate formulation with rbcL enzyme associated with chlorophyll metabolism, and its effects on varieties of sugarcane.

Background: The peroneal artery is known to give branches to the anterior and posterior tibial arteries. Scattered reports in the literature over the last decade failed to provide solid evidence as to the optimum strategy for below-knee targeted revascularization in limited-option patients with critical limb-treating ischemia (CLTI). We sought to determine the benefit of performing single peroneal tibial artery angioplasty revascularization compared with single non-peroneal angiosome-targeted tibial artery angioplasty revascularization for patients presented with CLTI.

Introduction: Marie-Unna hereditary hypotrichosis (MUHH) is an autosomal dominant disorder characterized by a specific pattern of hair loss. Initially described in 1925 by Marie-Unna in a German family spanning over seven generations, MUHH represents a previously unidentified form of congenital hypotrichosis. It typically presents as sparse hair at birth with a coarse texture, followed by regrowth during childhood then, finally, gradual hair loss at puberty, resembling pattern of androgenetic alopecia.

Objective: The purpose of this study was to evaluate the effect of different preparation depths (0, 2 and 4 mm) of different restoration designs (classic endocrown design versus overlay design) on marginal adaptation of restorations fabricated of two different restorative materials (lithium disilicate and PEEK).

Materials And Methods: Sixty mandibular natural molars were collected as abutments for the restorations of this study, and grouped in three main groups of different cavity depths (0, 2 and 4). Each group was divided into two subgroups according to material of fabrication to (L) for lithium disilicate (IPS emax CAD, Ivoclar vivadent, Switzarland) and (P) for PEEK (Bio-hpp, Bredent, Germany).

Arrhythmia is a common and serious global health problem, contributing to cardiovascular morbidity and mortality. The cardiac muscle is susceptible to ischemia-reperfusion (I/R) injury, which can lead to fatal arrhythmias during open-heart surgery. We investigated the potential prophylactic effect of angiotensin 1-7 (Ang 1-7) using an in vivo rat model of I/R injury and examined the underlying mechanisms.
