CsREV-CsTCP4-CsVND7 module shapes xylem patterns differentially between stem and leaf to enhance tea plant tolerance to drought.

Cultivating drought-tolerant tea varieties enhances both yield and quality of tea plants in northern China. However, the mechanisms underlying their drought tolerance remain largely unknown. Here we identified a key regulator called CsREV, which differentially regulates xylem patterns between leaves and stems, thereby conferring drought tolerance in tea plants.

CkREV regulates xylem vessel development in in response to drought.

Drought stress poses severe threat to the development and even the survival status of plants. Plants utilize various methods responding to drought, among which the forming of more well-developed xylem in leaf vein in woody plants deserves our attention. Herein, we report a transcription factor CkREV from HD-ZIP III family in , which possesses significant functions in drought response by regulating xylem vessel development in leaf vein.

A Missing Link in Radial Ion Transport: Ion Transporters in the Endodermis.

In higher plants, roots have important functions, such as the acquisition of water and ions, as well as transportation into the aerial parts of the plant via the xylem vessels. Radial ion transport in the root is strongly regulated in the endodermis, which is characterized by the presence of the Casparian strip (CS) and suberin lamellae. Although tremendous progress has been made with regard to the ion transporters and endodermal cells, little is known about the relationship between the ion transporters in the endodermis and ion homeostasis in aboveground tissues.

SOS1, HKT1;5, and NHX1 Synergistically Modulate Na Homeostasis in the Halophytic Grass .

is a typical salt-excluding halophytic grass with excellent salt tolerance. Plasma membrane Na/H transporter SOS1, HKT-type protein and tonoplast Na/H antiporter NHX1 are key Na transporters involved in plant salt tolerance. Based on our previous research, we had proposed a function model for these transporters in Na homeostasis according to the expression of and Na, K levels in responding to salt stress.

Assessment of Stress Tolerance, Productivity, and Forage Quality in T Transgenic Alfalfa Co-overexpressing and from .

Salinization, desertification, and soil nutrient deprivation are threatening the production of alfalfa ( L.) in northern China. We have previously generated T transgenic alfalfa co-overexpressing and genes with enhanced salt and drought tolerance.
